FEATURES OF CR510 The CR510 is programmed in the same way as the CR500 and executes existing CR500 programs. The CR510 has a clock and memory backed by an internal battery. This keeps the time and data while the CR510 is not connected to external power. GENERAL INTERNAL FLASH PROGRAM STORAGE Several programs can be stored in the CR510 Flash Memory and later recalled and run using the ∗D Mode. (Section 1.
This is a blank page.
SELECTED OPERATING DETAILS 1. Storing Data - Data are stored in Final Storage only by Output Processing Instructions and only when the Output Flag (Flag 0) is set. (Sections OV4.1.1 and 3.7.1) 5. Floating Point Format - The computations performed in the CR510 use floating point arithmetic. CSI's 4 byte floating point numbers contain a 23 bit binary mantissa and a 6 bit binary exponent. The largest and smallest numbers that can be stored 18 -19 and processed are 9 x 10 and 1 x 10 , respectively. (Section 2.
CAUTIONARY NOTES 1. Damage will occur to the analog input circuitry if voltages in excess of ±16 V are applied for a sustained period. Voltages in excess of ±5 V will cause errors and possible overranging on other analog input channels. 5. Voltage pulses can be counted by CR510 Pulse Counters configured for High Frequency Pulses. However, when the pulse is actually a low frequency signal (below about 10 Hz) AND the positive voltage excursion exceeds 5.
CR510 DATALOGGER OVERVIEW The CR510 is a fully programmable datalogger/controller with non-volatile memory and a battery backed clock in a small, rugged module. The combination of reliability, versatility, and telecommunications support make it a favorite choice for networks and single logger applications. Campbell Scientific Inc. provides four aids to operating the CR510: 1. 2. 3. 4.
CR510 OVERVIEW OV1.2 EXCITATION OUTPUTS The terminals labeled E1, and E2 are precision, switched excitation outputs used to supply programmable excitation voltages for resistive bridge measurements. DC or AC excitation voltages between -2500 mV and +2500 mV are user programmable (Section 9). OV1.3 PULSE INPUTS The terminals labeled P1, P2, and P3 are the pulse counter inputs for the CR510. P1 and P2 are programmable for high frequency pulse, low level AC, or switch closure (Section 9, Instruction 3).
CR510 OVERVIEW time when power is disconnected. The clock and Static Random Access Memory (SRAM) are powered by an internal lithium battery. OV2. MEMORY AND PROGRAMMING CONCEPTS OV2.1 INTERNAL MEMORY The standard CR510 has 128 K of Flash Electrically Erasable Programmable Read Only Memory (EEPROM) and 128 K Static Random Access Memory (SRAM). The Flash EEPROM stores the operating system and user programs. RAM is used for data and running the program.
CR510 OVERVIEW Flash Memory (EEPROM) Total 128 Kbytes Operating System (96 Kbytes) How it works: The Operating System is loaded into Flash Memory at the factory. System Memory is used while the CR510 is running calculations, buffering data and for general operating tasks. Any time a user loads a program into the CR510, the program is compiled in SRAM and stored in the Active Program areas. If the CR510 is powered off and then on, the Active Program is loaded from Flash and run.
CR510 OVERVIEW OV2.2 PROGRAM TABLES, EXECUTION INTERVAL AND OUTPUT INTERVALS The CR510 must be programmed before it will make any measurements. A program consists of a group of instructions entered into a program table. The program table is given an execution interval which determines how frequently that table is executed. When the table is executed, the instructions are executed in sequence from beginning to end.
CR510 OVERVIEW Each instruction in the table requires a finite time to execute. If the execution interval is less than the time required to process the table, an execution interval overrun occurs; the CR510 finishes processing the table and waits for the next execution interval before initiating the table. When an overrun occurs, decimal points are shown on either side of the G on the display in the LOG mode (∗0). Overruns and table priority are discussed in Section 1.1. OV2.2.2.
CR510 OVERVIEW INPUT/OUTPUT INSTRUCTIONS Specify the conversion of a sensor signal to a data value and store it in Input Storage. Programmable entries specify: (1) the measurement type (2) the number of channels to measure (3) the input voltage range (4) the Input Storage Location (5) the sensor calibration constants used to convert the sensor output to engineering units I/O Instructions also control analog outputs and digital control ports.
CR510 OVERVIEW OV3. COMMUNICATING WITH CR510 An external device must be connected to the CR510's Serial I/O port to communicate with the CR510. This may be either Campbell Scientific's CR10KD Keyboard Display or a computer/terminal. The CR10KD is powered by the CR510 and connects directly to the serial port via the SC12 cable (supplied with the CR10KD). No interfacing software is required. Computer communication and program editing is accomplished using Campbell Scientific's datalogger support software.
CR510 OVERVIEW TABLE OV3.
CR510 OVERVIEW OV4.1 PROGRAMMING SEQUENCE In routine applications, the CR510 measures sensor output signals, processes the measurements over some time interval and stores the processed results. A generalized programming sequence is: 1. Enter the execution interval. In most cases, the execution interval is determined by the desired sensor scan rate. 2. Enter the Input/Output instructions required to measure the sensors. 3.
CR510 OVERVIEW OV4.3 ENTERING A PROGRAM Programs are entered into the CR510 in one of three ways: 1. Keyed in using the CR10KD keyboard. 2. Loaded from a pre-recorded listing using the ∗D Mode. There are 2 types of storage/input: a. Stored on disk/sent from computer. b. Stored/loaded from Storage Module. 3. Loaded from internal Flash Memory or Storage Module upon power-up.
CR510 OVERVIEW there will be a 128 second delay before compiling and running the program. This can be used to edit or change the program before it starts running. To raise the ring line, press any key on the CR10KD keyboard display or call the CR510 with the computer during the power up sequence (i.e., while “HELLO” is displayed on the CR10KD).
CR510 OVERVIEW Wait a few seconds: 01:21.423 ∗ 2 8 1 A 6 A 1 0 A 7 A 0 01:0000 The CR510 has read the sensor and stored the result again. The internal temp is now 21.423 oC. The value is updated every 5 seconds when the table is executed. At this point the CR510 is measuring the temperature every 5 seconds and sending the value to Input Storage. No data are being saved. The next step is to have the CR510 send each reading to Final Storage. (Remember, the Output Flag must be set first.
CR510 OVERVIEW OV5.2 EDITING AN EXISTING PROGRAM When editing an existing program in the CR510, entering a new instruction inserts the instruction; entering a new parameter replaces the previous value. To insert an instruction, enter the program table and advance to the position where the instruction is to be inserted (i.e., P in the data portion of the display) key in the instruction number, and then key A.
CR510 OVERVIEW Instruction # (Loc.:Entry) Parameter (Par.#:Entry) 07: P73 01:1 02:10 03:2 08: P74 01:1 02:10 03:1 Description Maximize instruction One repetition Output time of daily maximum in hours and minutes Data source is Input Storage Location 1. Minimize instruction One repetition Output the time of the daily minimum in hours and minutes Data source is Input Storage Location 1. The program to make the measurements and to send the desired data to Final Storage has been entered.
CR510 OVERVIEW OV6. DATA RETRIEVAL OPTIONS There are several options for data storage and retrieval. These options are covered in detail in Sections 2, 4, and 5. Figure OV6.1-1 summarizes the various possible methods. Regardless of the method used, there are three general approaches to retrieving data from a datalogger. 1) On-line output of Final Storage data to a peripheral storage device.

SECTION 1. FUNCTIONAL MODES 1.1 DATALOGGER PROGRAMS - ∗1, ∗2, ∗3, AND ∗4 MODES Data acquisition and processing functions are controlled by user-entered instructions contained in program tables. Programming can be separated into 2 tables, each having its own user-entered execution interval. A third table is available for programming subroutines which may be called by instructions in Tables 1 or 2 or by a special interrupt. The ∗1 and ∗2 Modes are used to access Tables 1 and 2.
SECTION 1. FUNCTIONAL MODES 1.1.2 SUBROUTINES Table 3 is used to enter subroutines which may be called with Program Control Instructions in Tables 1 and 2 or other subroutines. The group of instructions which form a subroutine starts with Instruction 85, Label Subroutine, and ends with Instruction 95, End (Section 12). Subroutine 98 has the unique capability of being executed when port 2 goes high. This subroutine will interrupt Tables 1 and 2 (Section 1.1.3) when port 2 goes high.

SECTION 1. FUNCTIONAL MODES modes will return to the mode without recompiling. When the ∗0 or ∗B Mode is used to compile, all output ports and flags are set low, the timer is reset, and data values contained in Input and Intermediate Storage are reset to zero. When the ∗6 Mode is used to compile data values contained in Input Storage, the state of flags, control ports, and the timer (Instruction 26) are unaltered. Compiling always zeros Intermediate Storage. 1.
SECTION 1. FUNCTIONAL MODES Storage location 20, key in "*6 20 A". The ID portion of the display shows the last 2 digits of the location number. If the value stored in the location being monitored is the result of a program instruction, the value on the keyboard/display will be the result of the most recent scan and will be updated each time the instruction is executed. When using the ∗6 Mode from a remote terminal, a number (any number) must be sent before the value shown will be updated.
SECTION 1. FUNCTIONAL MODES memory is then displayed in K bytes. The size of memory can be displayed in the ∗B mode. histograms, etc. Intermediate Storage is not accessible by the user. Input Storage is used to store the results of Input/Output and Processing Instructions. The values stored in input locations may be displayed using the ∗6 Mode (Section 1.3). Each Input or Intermediate Storage location requires 4 bytes of memory. Each Final Storage location requires 2 bytes of memory.
SECTION 1. FUNCTIONAL MODES Flash Memory (EEPROM) Total 128 Kbytes Operating System (96 Kbytes) How it works: The Operating System is loaded into Flash Memory at the factory. System Memory is used while the CR510 is running for calculations, buffering data and general operating tasks. Any time a user loads a program into the CR510, the program is compiled in SRAM and stored in the Active Program areas. If the CR510 is powered off and then on, the Active Program is loaded from Flash and run.
SECTION 1. FUNCTIONAL MODES 1.5.2 ∗A MODE The ∗A Mode is used to 1) determine the number of locations allocated to Input Storage, Intermediate Storage, Final Storage Area 2, Final Storage Area 1, and Program Memory; 2) repartition this memory; 3) check the number of bytes remaining in Program memory; 4) erase Final Storage; and 5) to completely reset the datalogger. A second Final Storage area (Storage Area 2) can be allocated in the ∗A Mode.
SECTION 1. FUNCTIONAL MODES After repartitioning memory, the program must be recompiled. Compiling erases Intermediate Storage. Compiling with ∗0 erases Input Storage; compiling with ∗6 leaves Input Storage unaltered. If Intermediate Storage size is too small to accommodate the programs or instructions entered, the "E:04" ERROR CODE will be displayed in the ∗0, ∗6, and ∗B Modes. The user may remove this error code by entering a larger value for Intermediate Storage size.

SECTION 1. FUNCTIONAL MODES 1.7 ∗C MODE -- SECURITY The ∗C Mode is used to block access to the user's program information and certain CR510 functions. There are 3 levels of security, each with its own 4 digit password. Setting a password to a non-zero value "locks" the functions secured at that level. The password must subsequently be entered to temporarily unlock security through that level. Passwords are part of the program.
SECTION 1. FUNCTIONAL MODES program will be automatically loaded and run when the CR510 is powered up. (If a Storage Module with a program 8 is connected when the CR510 powers-up, the Storage Module program 8 will be loaded into the CR510 and become the active program.) Scrolling through the program names begins with the oldest program. "A" advances to the next newer program, "B" backs up to the next older program.

SECTION 1. FUNCTIONAL MODES This is a blank page.
SECTION 2. INTERNAL DATA STORAGE 2.1 FINAL STORAGE AREAS, OUTPUT ARRAYS, AND MEMORY POINTERS Final Storage is the memory where final processed data are stored. Final Storage data are transferred to your computer or external storage peripheral. The size of Final Storage is expressed in terms of memory locations; one memory location is two bytes.
SECTION 2. INTERNAL DATA STORAGE Output Processing Instructions store data into Final Storage only when the Output Flag is set. The string of data stored each time the Output Flag is set is called an OUTPUT ARRAY. The first data point in the output array is a 3 digit OUTPUT ARRAY ID. This ID number is set in one of two ways: 1.
SECTION 2. INTERNAL DATA STORAGE seventh digit. For example, the resolution of 97,386,924 is better than 10. The resolution of 0.0086731924 is better than 0.000000001. 2.2 DATA OUTPUT FORMAT AND RANGE LIMITS Data are stored internally in Campbell Scientific's Binary Final Storage Format (Appendix B.2). Data may be sent to Final Storage in either LOW RESOLUTION or HIGH RESOLUTION format.
SECTION 2. INTERNAL DATA STORAGE another memory location may be entered, followed by the "A" key to jump to the start of the Output Array equal to or just ahead of the location entered. Whenever a location number is displayed by using the "#" key, the corresponding data point can be displayed by pressing the "C" key. TABLE 2.3-1. ∗7 Mode Command Summary Key A B # The same element in the next Output Array with the same ID can be displayed by hitting #A.
SECTION 3. INSTRUCTION SET BASICS The instructions used to program the CR510 are divided into four types: Input/Output (I/O), Processing, Output Processing, and Program Control. I/O Instructions are used to make measurements and store the readings in input locations or to initiate analog or digital port output. Processing Instructions perform mathematical operations using data from Input Storage locations and place the results back into specified Input Storage locations.
SECTION 3. INSTRUCTION SET BASICS Loop Index, allows the increment step to be changed. See Instructions 87 and 90, Section 12, for more details. To index an input location (4 digit integer), C or "-" is pressed after keying the value but before entering the parameter. Two minus signs (--) will be displayed to the right of the parameter. Voltages greater than 16 volts may permanently damage the CR510. NOTE: Voltages in excess of 5.5 volts applied to a control port can cause the CR510 to malfunction. 3.
SECTION 3. INSTRUCTION SET BASICS The instructions to output the average temperature every 10 minutes are in Table 2 which has an execution interval of 10 seconds. The temperature will be measured 600 times in the 10 minute period, but the average will be the result of only 60 of those measurements because the instruction to average is executed only one tenth as often as the instruction to make the measurement.

SECTION 3. INSTRUCTION SET BASICS 3.10 ERROR CODES There are four types of errors flagged by the CR510: Compile, Run Time, Editor, and ∗D Mode. Compile errors are errors in programming which are detected once the program is entered and compiled for the first time (∗0, ∗6, or ∗B Mode entered). If a programming error is detected during compilation, an E is displayed with the 2 digit error code.
SECTION 3.
SECTION 4. EXTERNAL STORAGE PERIPHERALS External data storage devices are used to provide a data transfer medium that the user can carry from the test site to the lab and to supplement the internal storage capacity of the CR510, allowing longer periods between visits to the site. The standard data storage peripheral for the CR510 is the Storage Module (Section 4.4). Output to a printer or related device is also possible (Section 4.3).
SECTION 4. EXTERNAL STORAGE PERIPHERALS Instruction 96 has a single parameter which specifies the peripheral to send output to. Table 4.1-1 lists the output device codes. connector becomes available, each device in the queue gets its turn. Code Device An output request is not put in the queue if the same device is already in the queue. The data contained in the queue (and which determine a unique entry) are the device, baud rate (if applicable), and the Final Storage Area.
SECTION 4. EXTERNAL STORAGE PERIPHERALS 4.2 MANUALLY INITIATED DATA OUTPUT - ∗8 MODE Data transfer to a peripheral device can be manually initiated in the ∗8 Mode. This process requires that the user have access to the CR510 through a terminal or the CR10KD. The ∗8 Mode allows the user to retrieve a specific block of data, on demand, regardless of whether or not the CR510 is programmed for on-line data output.
SECTION 4. EXTERNAL STORAGE PERIPHERALS FIGURE 4.3-1. Example of CR510 Printable ASCII Output Format 4.3.2 COMMA SEPARATED ASCII Comma Separated ASCII strips all IDs, leading zeros, unnecessary decimal points and trailing zeros, and plus signs. Data points are separated by commas. Arrays are separated by Carriage Return Line Feed. Comma Separated ASCII requires approximately 6 bytes per data point. Example: 1,234,1145,23.65,-12.26,625.9 1,234,1200,24.1,-10.98,650.3 4.
SECTION 4. EXTERNAL STORAGE PERIPHERALS Storage Module with the lowest address that is not full (fill and stop configuration only) and addresses it. In other words, if a single Storage Module is connected, and it is not full, address 1 will address that Storage Module regardless of the address that is assigned to the Module. Address 1 would be used with Instruction 96 if several Storage Modules with different addresses were connected to the CR510 and were to be filled sequentially.
SECTION 4. EXTERNAL STORAGE PERIPHERALS TABLE 4.5-1. ∗9 Commands for Storage Module COMMAND DISPLAY DESCRIPTION 1 01: 0000 3 01: XX 03: 01 4 04: XX RESET, enter 248 to erase all data and programs. While erasing, the SM checks memory. The number of good chips is then displayed (6 for SM192, 22 SM716). INSERT FILE MARK, 1 indicates that the mark was inserted, 0 that it was not.
SECTION 5. TELECOMMUNICATIONS Telecommunications is used to retrieve data from Final Storage directly to a computer/terminal and to program the CR510. Any user communication with the CR510 that makes use of a computer or terminal instead of the CR10KD is through Telecommunications.
SECTION 5. TELECOMMUNICATIONS 4. An illegal character increments a counter and zeros the command buffer, returning a ∗. 5. CR to datalogger means "execute". 6. CRLF from datalogger means "executing command". 7. ANY character besides a CR sent to the datalogger with a legal command in its buffer causes the datalogger to abort the command sequence with CRLF∗ ∗ and to zero the command buffer. 8. All commands return a response code, usually at least a checksum. 9.
SECTION 5. TELECOMMUNICATIONS TABLE 5.1-1. Telecommunications Commands Command [F.S. Area]A Description SELECT AREA/STATUS - If 1 or 2 does not precede the A to select the Final Storage Area, the CR510 will default to Area 1. All subsequent commands other than A will address the area selected.
SECTION 5. TELECOMMUNICATIONS 3142J K TOGGLE FLAGS AND SET UP FOR K COMMAND - Used in the Monitor Mode and with the Heads Up Display. See Appendix C for details. CURRENT INFORMATION - In response to the K command, the CR510 sends datalogger time, user flag status, the data at the input locations requested in the J command, and Final Storage Data if requested by the J command. Used in the Monitor Mode and with Heads Up Display. See Appendix B.
SECTION 6. 9-PIN SERIAL INPUT/OUTPUT 6.1 PIN DESCRIPTION All external communication peripherals connect to the CR510 through the 9-pin subminiature Dtype socket connector located on the front of the Terminal Strip (Figure 6.1-1). Table 6.1-1 shows the I/O pin configuration, and gives a brief description of the function of each pin. FIGURE 6.1-1. 9-pin Female Connector TABLE 6.1-1. Pin Description ABR = Abbreviation for the function name. PIN = Pin number. O = Signal Out of the CR510 to a peripheral.
SECTION 6. 9-PIN SERIAL INPUT/OUTPUT (ME) MODEM (COM200 RF95 SC32A) FIGURE 6.2-1. Hardware Enabled and Synchronously Addressed Peripherals 6.2 ENABLING AND ADDRESSING PERIPHERALS While several peripherals may be connected in parallel to the 9-pin port, the CR510 has only one transmit line (pin 9) and one receive line (pin 4, Table 6.1-1).
SECTION 6. 9-PIN SERIAL INPUT/OUTPUT Synchronously addressed peripherals include the CR10KD Keyboard Display, Storage Modules, SDC99 Synchronous Device Interface (SDC99), and RF95 RF Modem when configured as a synchronous device. The SDC99 interface is used to address peripherals which are normally pin enabled (Figure 6.2-1). 6.
SECTION 6. 9-PIN SERIAL INPUT/OUTPUT 6.5 MODEM/TERMINAL PERIPHERALS The CR510 considers any device with an asynchronous serial communications port which raises the Ring line (and holds it high until the ME line is raised) to be a modem peripheral. Modem/terminals include Campbell Scientific phone modems, and most computers, terminals, and modems using the SC32A Optically Isolated RS232 Interface or the SC932 RS232 DCE Interface. When a modem raises the Ring line, the CR510 responds by raising the ME line.
SECTION 6. 9-PIN SERIAL INPUT/OUTPUT State 2 requires all SDs to drop the Ring line and prepare for addressing. The CR510 then synchronously clocks 8 bits onto TXD using CLK/HS as a clock. The least significant bit is transmitted first and is always logic high. Each bit transmitted is stable on the rising edge of CLK/HS. The SDs shift in bits from TXD on the rising edge of CLK/HS provided by the CR510. The CR510 can only address one device per State 2 cycle.

An ASCII character is a binary digital code composed of a combination of seven "bits", each bit having a binary state of 1 (one) or 0 (zero).
SECTION 6. 9-PIN SERIAL INPUT/OUTPUT IF NOTHING HAPPENS If the CR510 is connected to the SC32A RS232 interface and a modem/terminal, and an "∗" is not received after sending carriage returns: 1. Verify that the CR510 has power AT THE 12V AND GROUND INPUTS, and that the cables connecting the devices are securely connected. 2. Verify that the port of the modem/terminal is an asynchronous serial communications port configured as DTE (see Table 6.7-2).
SECTION 7. MEASUREMENT PROGRAMMING EXAMPLES This section gives some examples of Input Programming for common sensors used with the CR510. These examples detail only the connections, Input, Program Control, and Processing Instructions necessary to perform measurements and store the data in engineering units in Input Storage. Output Processing Instructions are omitted (see Section 8 for some processing and program control examples).
SECTION 7. MEASUREMENT PROGRAMMING EXAMPLES CR510 FIGURE 7.2-1. Typical Connection for Active Sensor with External Battery Ground at the LI-6262 is 0.065 V higher than ground at the CR510. The LI-6262 can be programmed to output a linear voltage (0 to 100 mV) that is proportional to differential CO2, 100 µmol/mol full scale, or 1 µmol/mol/mV. If the output is measured with a single-ended voltage measurement, it is 0.065 V or 65 µmol/mol high.

Counts from long intervals will be used, as the final output desired is total rainfall (obtained with Instruction 72, Totalize).
SECTION 7. MEASUREMENT PROGRAMMING EXAMPLES Next solve for Vx: Vx = I(R1+Rs+Rf) = 2.21 V If the actual resistances were the nominal values, the CR510 would not over range with Vx = 2.2 V. To allow for the tolerances in the actual resistances, it is decided to set Vx equal to 2.1 volts (e.g., if the 10 kohms resistor is 5% low, then Rs/(R1+Rs+Rf)=115.54/9715.54, and Vx must be 2.102 V to keep Vs less than 25 mV). The result of Instruction 9 when the first differential measurement (V1) is not made on the 2.
SECTION 7. MEASUREMENT PROGRAMMING EXAMPLES 7.7 100 OHM PRT IN 3 WIRE HALF BRIDGE The temperature measurement requirements in this example are the same as in Section 7.8. In this case, a three wire half bridge, Instruction 7, is used to measure the resistance of the PRT. The diagram of the PRT circuit is shown in Fig. 7.7-1. As in the example in Section 7.8, the excitation voltage is calculated to be the maximum possible, yet allow the +25 mV measurement range.

SECTION 7. MEASUREMENT PROGRAMMING EXAMPLES Even with an excitation voltage (Vx) equal to 2500 mV, Vs can be measured on the +2.5 mV scale (40°C = 115.8 ohms = -2.006 mV, 60°C = 123.6 ohms = 1.714 mV). There is a change of approximately 2 mV from the output at 40°C to the output at 51°C, or 181 µV/°C. With a resolution of 0.33 µV on the 2.5 mV range, this means that the temperature resolution is 0.0018°C. The 5 ppm per °C temperature coefficient of the fixed resistors was chosen so that their 0.

SECTION 7. MEASUREMENT PROGRAMMING EXAMPLES of the bridge in the load cell is 350 ohms. The voltage drop across the load cell is equal to the voltage at the CR510 multiplied by the ratio of the load cell resistance, Rs, to the total resistance, RT, of the circuit. If Instruction 6 were used to measure the load cell, the excitation voltage actually applied to the load cell, V1, would be: V1 = Vx Rs/RT = Vx 350/(350+33) = 0.91 Vx Where Vx is the excitation voltage.
SECTION 7. MEASUREMENT PROGRAMMING EXAMPLES When the experiment is started, the water content of the soil in the lysimeter is approximately 25% on a volume basis. It is decided to use this as the reference (i.e., 0.25 x 1500 mm = 375 mm). The experiment is started at the beginning of what is expected to be a period during which evapotranspiration exceeds precipitation. Instruction 9 is programmed with the correct multiplier and no offset.

SECTION 8. PROCESSING AND PROGRAM CONTROL EXAMPLES The following examples are intended to illustrate the use of Processing and Program Control Instructions, flags, dual Final Storage, and the capability to direct the results of Output Processing Instructions to Input Storage. The specific examples may not be as important as some of the techniques employed, for example: Directing Output Processing to Input Storage is used in the Running Average and Rainfall Intensity examples (8.1 and 8.2).
SECTION 8. PROCESSING AND PROGRAM CONTROL EXAMPLES In the above example, all samples for the average are stored in input locations. This is necessary when an average must be output with each new sample. In most cases, averages are desired less frequently than sampling. For example, it may be necessary to sample some parameter every 5 seconds and output every hour an average of the previous three hours' readings. If all samples were saved, this would require 2160 input locations.

SECTION 13. CR510 MEASUREMENTS 13.1 FAST AND SLOW MEASUREMENT SEQUENCE The CR510 makes voltage measurements by integrating the input signal for a fixed time and then holding the integrated value for the analog to digital (A/D) conversion. The A/D conversion is made with a 13 bit successive approximation technique which resolves the signal voltage to approximately one part in 7500 of the full scale range on a differential measurement (e.g., 1/7500 x 2.5 V = 333 uV).
SECTION 13. CR510 MEASUREMENTS FIGURE 13.2-1. Timing of Single-Ended Measurement FIGURE 13.2-2. Differential Voltage Measurement Sequence 13.2 SINGLE-ENDED AND DIFFERENTIAL VOLTAGE MEASUREMENTS NOTE: Either the high or low side of a differential channel can be used for singleended measurements. Each side must be counted when numbering single-ended channels; e.g., the high and low sides of differential channel 1 are single-ended channels 1 and 2, respectively.
SECTION 13. CR510 MEASUREMENTS which both inputs of a differential measurement must lie in order for the differential measurement to be made. For example, if the high side of a differential input is at 2 V and the low side is at 1 V relative to CR510 ground, there is no problem; a measurement made on the +2.5 V range would indicate a signal of 1 V. However, if the high input is at 2.8 V and the low input is at 2 V, the measurement cannot be made because the high input is outside of the common mode range.
SECTION 13. CR510 MEASUREMENTS FIGURE 13.3-1. Input Voltage Rise and Transient Decay 13.3.1 THE INPUT SETTLING TIME CONSTANT The rate at which an input voltage rises to its full value or that a transient decays to the correct input level are both determined by the input settling time constant. In both cases the waveform is an exponential. Figure 13.3-1 shows both a rising and decaying waveform settling to the signal level, Vso. The rising input voltage is described by Equation 13.

Source Resistance Model for Half Bridge Connected to the CR510 DETERMINING SOURCE RESISTANCE The source resistance used to estimate the settling time constant is the resistance the CR510 input "sees" looking out at the sensor. For our purposes the source resistance can be defined as the resistance from the CR510 input through all external paths back to the CR510. Figure 13.

Resistive Half Bridge Connected to Single-Ended CR510 Input Ro, the source resistance, is not constant because Rb varies from 0 to 10 kohms over the 0 to 360 degree wind direction range. The source resistance is given by: Wind Direction Ro = Rd+(Rb(Rs-Rb+Rf)/(Rs+Rf)) = Rd+(Rb(20k-Rb)/20k) [13.3-12] Note that at 360 degrees, Ro is at a maximum of 6k (Rb=10k) and at 0 degrees, Ro is 1k (Rb=0).

SECTION 13. CR510 MEASUREMENTS source resistance at point P (column 5) is essentially the same as the input source resistance of configuration A. Moving Rf' out to the thermistor as shown in Figure 13.3-7C optimizes the signal settling time because it becomes a function of Rf and Cw only. Columns 4 and 7 list the signal voltages as a function of temperature using a 2000 mV excitation for configurations A and C, respectively.

Figure 13.4-1 shows the circuits that would typically be measured with these instructions.
SECTION 13. CR510 MEASUREMENTS integration as is normally the case (Section 13.2). The result stored is the voltage measured. Instruction 8 does not have as good resolution or common mode rejection as the ratiometric bridge measurement instructions. It does provide a very rapid means of making bridge measurements as well as supplying excitation to circuitry requiring differential measurements. This instruction does not reverse excitation.

SECTION 13. CR510 MEASUREMENTS Calculating the actual resistance of a sensor which is one of the legs of a resistive bridge usually requires the use of one or two Processing Instructions in addition to the bridge measurement instruction. Instruction 59 takes a value, X, in a specified input location and computes the value MX/(1-X), where M is the multiplier and stores the result in the original location. Instruction 42 computes the reciprocal of a value in an input location. Table 13.
SECTION 13. CR510 MEASUREMENTS 13.5 RESISTANCE MEASUREMENTS REQUIRING AC EXCITATION Some resistive sensors require AC excitation. These include the 207 Relative Humidity Probe, soil moisture blocks, water conductivity sensors, and wetness sensing grids. The use of DC excitation with these sensors can result in polarization, which will cause an erroneous measurement, and may shift the calibration of the sensor and/or lead to its rapid decay.
SECTION 13. CR510 MEASUREMENTS In Figure 13.5-2, Vx is the excitation voltage, Rf is a fixed resistor, Rs is the sensor resistance, and RG is the resistance between the excited electrode and CR510 earth ground. With RG in the network, the measured signal is: Rs V1 = Vx __________________ (Rs+Rf) + RsRf/RG adjusting the calibration coefficients the accuracy of the voltage measurements is maintained over the -25 to +50°C operating range of the CR510. Calibration is executed under four conditions: 1.
SECTION 13. CR510 MEASUREMENTS table WILL be overrun by the automatic calibration. If an overrun occurs every time calibration is executed, then 1 execution is skipped for every 512 times that the program table is executed. If the measurements are being averaged, the effect of the overrun is negligible. Program table overruns are indicated by the appearance of two decimals on either side of the sixth digit on the CR10KD and are also stored in memory (Section 1.7).
SECTION 14. INSTALLATION AND MAINTENANCE 14.1 PROTECTION FROM THE ENVIRONMENT The normal environmental variables of concern are temperature and moisture. The standard CR510 is designed to operate reliably from -25° to +50°C (-55° to +85°C, optional). Internal moisture damage is reduced with a water resistant conformal coating on the current board. Extra desiccant should also be placed in the enclosure to prevent corrosion. Campbell Scientific offers fiberglass enclosures for housing a CR510 and peripherals.
SECTION 14. INSTALLATION AND MAINTENANCE System operating time for the batteries can be determined by dividing the battery capacity (amp-hours) by the average system current drain. The CR510 draws <1 mA in the quiescent state, 13 mA while processing, and 46 mA during an analog measurement; the length of operating time for each datalogger instruction is listed in the programming section. Typical current requirements for common CR510 peripherals are given in Table 14.2-1. 14.

SECTION 14. INSTALLATION AND MAINTENANCE 14.7 GROUNDING 14.7.1 PROTECTION FROM LIGHTNING Primary lightning strikes are those where lightning hits the datalogger or sensors directly. Secondary strikes occur when the lightning strikes somewhere near the system and induces a voltage in the wires. The purpose of an earth ground is to minimize damage to the system by providing a low resistance path around the system to a point of low potential.
SECTION 14. INSTALLATION AND MAINTENANCE In the field, an earth ground may be created through a grounding rod. A 12 AWG or larger wire should be run between a Terminal Strip power ground (G) terminal and the earth ground. Campbell Scientific's CM10 and CM6 Tripods and UT3 Tower come complete with ground and lightning rods, grounding wires, and appropriate ground wire clamps. 14.7.

TABLE DATA ADDENDUM TD and PakBus Operating System Addendum for CR510, CR10X, and CR23X Manuals AD1 Major Differences Table Data (TD) operating systems have two major differences from the standard operating systems: First - the namesake - in the way data are stored internally and second, in the options available for transferring that data to external devices. The standard operating systems support both on site external storage (i.e., storage modules) that may be manually retrieved and telecommunications.
TABLE DATA ADDENDUM AD2 Overview of Data Storage Tables Within a data table, data is organized in records and fields. Each row in a table represents a record and each column represents a field. To understand the concept of tables it may be helpful to consider an example. A CR10-TD is to be used to monitor 3 thermocouples (TC). Each hour a temperature for each of the three TC is to be stored. The table has 4 fields : "DATE_TIME TEMP1 TEMP2 TEMP3". Each hour a new "record" would be added.
TABLE DATA ADDENDDUM • Check the Maximum and Minimum Instructions (Instructions 73 and 74) as there is only one option to store time with the value. • Edit Input Location labels removing all spaces and special characters. Only letters, numbers, and the “_” characters are allowed. Labels should start with a letter. • Add labels for the Final Storage values. Use the same character as are allowed for Input Location labels. See Section 2.1 AD3.
TABLE DATA ADDENDUM AD4 Summary of Differences from the Datalogger Manual: Section Overview Differences Section 1 Section 1.5 A Mode is replaced by addendum – the TD loggers allocate memory differently. Section 1.8 - *D Mode is replaced by TD Addendum – TD loggers do not support storeing multiple programs or Storage Modules. PakBus Settings are added to the *D Mode. Replaced entirely by TD Addendum. Section 3.7.1 does not apply to the TD operating system which does not use Output Flag 0. Table 3.

It is from Final Storage that data is transferred to your computer. With the TD datalogger, Final Storage is organized into Data Storage Tables. These data tables should not be confused with the program tables *1, *2, and *3 that contain the datalogger program.
TD ADDENDUM—SECTION 2. INTERNAL DATA STORAGE • The output interval is not an even multiple of the scan rate (table execution interval). • Table execution is such that Instruction 84 is not executed each scan. • Table overruns occur. • Watchdog errors (E08) occur. 2.1.2 RECORD NUMBERS In addition to a timestamp, each record has record number. The record numbers are unique within a data table. Record numbers are 4 byte unsigned numbers ranging from 0 to 4,294,967,296.
TD ADDENDUM—SECTION 2. INTERNAL DATA STORAGE The Timestamp and record number labels are added automatically. 2.2 DATA OUTPUT FORMAT AND RANGE LIMITS Data is stored internally in Campbell Scientific's Binary Final Storage Format (Appendix C.2). Data may be sent to Final Storage in either LOW RESOLUTION or HIGH RESOLUTION format. 2.2.1 RESOLUTION AND RANGE LIMITS Low resolution data is a 2 byte format with 4 significant digits and a maximum magnitude of +7999.
TD ADDENDUM—SECTION 2. INTERNAL DATA STORAGE TABLE 2.3-1. *7 Mode Command Summary KEY A ACTION "Advances" along a record, when the end of the record is reached the 'cursor' advances to the first field in the next record. B "Backs" up along a record, wraps to the last element in the previous record C "Climbs" up the table, toward the oldest data, stops on oldest record. D "Drops" down the table, toward the newest data, stops on newest record. # Enter Time Mode to display timestamp.
SECTION 3. INSTRUCTION SET BASICS Section 3.7.1 does not apply to the TD operating system which does not use Output Flag 0. Table 3.8-1 Valid Flag Commands are 11 – 19 to set high and 21- 29 to set low. Because the TD operating system does not use Flag 0, Commands 10 and 20 are not valid with the TD operating system. The following table replaces Table 3.10-1 for the TD operating system. TABLE 3.10-1.

TD ADDENDUM—SECTION 8. PROCESSING AND PROGRAM CONTROL EXAMPLES 8.5 SDM-A04 ANALOG OUTPUT MULTIPLEXER TO STRIP CHART This example illustrates the use of the SDMA04 4 Channel Analog Output Multiplexer to output 4 analog voltages to strip chart. While of questionable value because of current requirements and strip chart reliability, some archaic regulations require strip chart backup on weather data. The SDM-A04 may be used with the CR10 to provide analog outputs to strip charts.

SECTION 11. OUTPUT PROCESSING INSTRUCTIONS Instructions 73 – Maximum and 74 – Minimum have only one time option. (Time is output as a quoted string.) Instruction 80 – Set Active Storage Area, is not in the TD operating system. Its functions are included in Instruction 84 – Data Table. Instruction 84 is only in the TD operating system. *** 73 MAXIMUM *** FUNCTION This instruction stores the MAXIMUM value taken (for each input location specified) over a given output interval.
TD ADDENDUM—SECTION 11. OUTPUT PROCESSING INSTRUCTIONS records. If 0 is entered, records will be automatically allocated such that all automatic tables will be filled at the same time. If some tables specify the number of records and some tables are automatically allocated, the specified records will be allocated first, and then the remaining memory will be divided among the automatically allocated tables such that they will be filled at the same time.
Section 12. Program Control Instructions The TD operating system does not use the output Flag 0. Commands dealing with it are not valid. Instructions 96 – Serial Output, 98 – Send Character, and 111 – Load Program from Flash, are NOT in the TD operating system. The instructions described in this section are only in the PakBus operating system. Wireless Networks More recent CR10X, CR510, and CR23X dataloggers with the PakBus operating system use the PakBus communications protocol.
Section 12. Program Control Instructions TABLE 12-1. CR205/CR210/CR215 in PakBus Network General Description PRO CON/limitations PakBus Instructions used in Datalogger Programming 12-2 Stand Alone Datalogger CR205 is programmed as a stand alone datalogger.

Stand Alone SendGetData P190 Wireless Sensor P193 Datalogger Radio address, net address, and hop sequence must be the same in all CR2xxs and RF400s in the network. Because only one header length can be set for a radio, only one power cycling interval should be used in network; i.
Section 12. Program Control Instructions Notes: Edlog allocates only one of the input locations used in parameters 5 and 7 of this instruction. The additional input locations must be inserted manually using the Input Location Editor. If this instruction is used to retrieve a value or set a value in the remote datalogger's public (or input location) table (i.e., code 26 or 27 is used in parameter 3), Instruction 63 or 68 must follow this instruction to enter the variable name that will be accessed.
Section 12. Program Control Instructions PakBus Communication The unique address for the datalogger in the PakBus network that will be communicated with using this instruction. The Pakbus address is set in the datalogger's *D15 mode. Modbus Communication The unique address for the datalogger in a Modbus network that will be communicated with using this instruction (the slave device). The Modbus address is set in the datalogger's *D8 mode. The valid range of IDs for a Modbus slave device are 1 - 99.
Section 12. Program Control Instructions desirable to delay execution of subsequent instructions if those instructions perform further processing on the response from the remote. Security Enter the level 2 security code for the remote datalogger in the PakBus network that will be communicated with using this instruction when Command 22 is used for parameter 3 (send input location data to another datalogger).
Section 12. Program Control Instructions Remote Location PakBus Communication If data is being received from another datalogger in the PakBus network (Parameter 3 set to 21), this is the first input location in the remote datalogger from which to retrieve the data. If data is being sent to another datalogger in the PakBus network (Parameter 3 set to 22), this is the first input location in the remote datalogger in which to store the first data value.
Section 12. Program Control Instructions or unpacked with the least significant bit of the first byte, starting at this location. Incoming discrete values are set to -1.0 for ON and 0 for OFF. Outgoing discrete values are translated as 0.0 to OFF and non-zero to ON. For general information on input locations, see Input Locations. Result Code Location The input location in which to store the results of the data transfer.
Section 12. Program Control Instructions This instruction is not necessary in networks with wireless sensors and only one Master datalogger, because the Wireless Network Master (P193) and Wireless Network Remote (P196) instructions perform these functions automatically. This instruction can also be used to remove a datalogger from the PakBus network. 3: 1: 2: 3: PakBus - Send Message (P192) 00 Port 0000 Address 2 Clock Report Message Type Entry 2 13 Description Clock report; sends the current time.
Section 12. Program Control Instructions Edlog allocates only one of the input locations used in parameters 7, 9, and 10 of this instruction. The additional input locations must be inserted manually using the Input Location Editor. For information on manually inserting input locations, refer to Manually Inserting Input Locations Into Edlog. Number of Remotes The number of remote dataloggers/wireless sensors in the PakBus network that will be communicated with using this instruction.
Section 12. Program Control Instructions Example To set up the remotes for an hourly transmission at 15 minutes past the hour, the Time into Transmit Interval would be set at 900 and the Transmit Interval would be set at 3600. Transmit Delay Between Remotes The amount of delay, in seconds, between transmission from each remote. If this parameter is left at 0, the master datalogger will automatically assign the delay based on the routing table (usually about 3 seconds between remotes).
Section 12. Program Control Instructions For general information on input locations, see Input Locations. Swath to Send The number of data values that will be sent to each remote when data is transferred. First Location to Send The input location which holds the first value that should be sent to the dataloggers/wireless sensors in the group. The range of values sent to the remote(s) is determined by the Swath to Send parameter (parameter 8).
Section 12. Program Control Instructions Location with Seconds Until Transmit The input location in which to store the number of seconds until it is time to transmit to the host datalogger. Use Remote Clock Report (P195) A program control instruction that sets a remote datalogger's clock based on the clock value transmitted from the host (or master) datalogger specified by the address provided in parameter 1.
Section 12. Program Control Instructions Swath to Receive From Master The number of data values that will be received from the host (master) datalogger when data is transferred. If the host sends less than the number of values indicated by the swath, the remaining locations will be filled with an overrange value (-99999). If the host sends more than the number of data values indicated by the swath, the extra values will be discarded by the local datalogger.
Section 12. Program Control Instructions For general information on input locations, see Input Locations. Result Code Location The input location in which a code is stored to indicate the result of the data transfer. A 0 indicates the data transfer was successful; any number greater than 0 indicates a failure. A -2 indicates that communication was established with the datalogger at the specified address, but the datalogger was not programmed as a host (master) datalogger using Instruction 193.
Section 12. Program Control Instructions Result Location Result Code -1001 -1002 -1003 0 >1 Description The attempted setting is a read-only setting Out of space in the remote Syntax error Success Number of communication failures Routing Table Information (P199) A program control instruction that is used to store the datalogger's routing table information in a series of input locations. This instruction is used most often as a trouble-shooting tool.
Section 12.
Section 12. Program Control Instructions desired interval in the Communications Interval field. This option is the same as the datalogger's *D18 mode. In some networks, a beacon interval might interfere with regular communication in the PakBus network (such as in an RF network), since the beacon is broadcast to all devices within range.
