2... OMP-MODL System Base 2... OMP-MODL SYSTEM BASE SYSTEM BASE OVERVIEW System Base refers to the main data logger unit composed of a stack of two interconnected modules... the MLCPU-1 module and the MLAD-1 module. These two modules combined house the main microprocessor and support circuitry, memory, power supplies, A to D converter as well as 6 inputs (4 analog, 1 Cold Junction Compensation temperature and 1 digital) and 4 outputs.
2... OMP-MODL System Base unit. As modules are added to the stack, the connectors must be aligned and plugged together as the modules slide together. Four side retaining screws are then installed into the sides to securely hold the assembly together. Top Plate A flat metal plate is provided to cover the top end of the module stack in units not equipped with the ML-DISP Display and User button module (Refer to the ML-DISP module in Chapter 3).
2... OMP-MODL System Base TIP: For applications utilizing loggers equipped with a large number of Interface Modules, the stack can become rather tall. In these applications, side plate mounting may be desired. Contact LBI for details on the side mounting bracket..

2... OMP-MODL System Base Feedback LED Indicator: The green Feedback LED is used to provide feedback to the User as buttons are pressed and the logger performs various commands.
2... OMP-MODL System Base FYI: The label ENABLE was chosen rather than START for a subtle but important reason. When the ENABLE button is pressed, execution of the Program Net commences... but that does not necessarily mean that data logging to memory has started. For example, a Program Net is developed and uploaded to the OMPMODL that includes a setpoint function that controls logging to memory. For example log only when the kiln temperature exceeds 150F.
2... OMP-MODL System Base 3-Button System Initialization: A complete initialization of the logger that will clear data memory and program memory can be performed using the ENABLE, STOP and RESET buttons.
2... OMP-MODL System Base CAUTION The RS-232 jack is only for connection of RS-232 type signals (via the supplied cable and adapters) and is not for direct connection of a telephone line. For telephone modem communication with the OMPMODL, utilize the OMP-MODL Modem Interface Module. Direct connection of a telephone line to the RS-232 jack may result in permanent damage to the OMPMODL. For longer communication distances, a longer cable can be used.
2... OMP-MODL System Base Terminal Strip Connections The MLCPU-1 is provided with a terminal strip connector for connection of power, input and output wiring (Figure 2... -4). The terminal strip connector can be unplugged from the module allowing for quick disconnect and reconnection of wiring.

2... OMP-MODL System Base EPROM To change the setting, access must be gained to the jumper on the top of the MLCPU-1 module (Figure 2... -5). Per the assembly / disassembly instructions in Chapter 3, open the logger to gain access to the top of the MLCPU-1. The Hi/Lo jumper is installed on two pins of a 3 pin header. To program a new range, remove and reinstall the jumper on the desired pair of pins. CPU HIGH RANGE LOW RANGE ML005 Figure 2...
2... OMP-MODL System Base Relay R2 (Terminals 5 & 6) Wiring connections for Output Relay 2. The relay is a normally open device with contacts rated for 500 ma MAX at 32VDC MAX. Operation is dependent on logic associated with the Relay Alarm #2 icon within the Program Net executing in the logger. +5V (Terminal 7) This terminal provides a current limited, voltage regulated +5 VDC supply for alarm and sensor excitation applications.
2... OMP-MODL System Base RTC / Memory Backup Battery The OMP-MODL utilizes static ram for internal data storage which requires a constant power supply to maintain its memory. Similarly, the Real Time Clock (RTC) that keeps track of the date and time within the OMP-MODL runs continually whether the main power switch is ON or OFF. When the main power is ON, the memory and RTC draw their power from the D-Cell batteries (or a connected external power supply).
2... OMP-MODL System Base A terminal strip is provided at one end of the module for the connection of sensor and signal wiring. The terminal strip can be unplugged for mass connect/disconnect of the field wiring.

2... OMP-MODL System Base INTERNAL CJC SENSING APPLICATIONS: For OMP-MODL applications with thermocouple inputs connected directly to the MLAD-1 or any installed MLIM-1 Analog Input modules, a wire jumper must be installed across terminals 13 and 14 (marked INT for internal). The OMP-MODL is shipped from the factory with this jumper installed.

3... INTERFACE MODULES Commonly, this fuse is blown during installation of 420mA current channels where the power supply powering the 4-20mA transmitter is accidently shorted directly across the logger input channel. To avoid this inconvenience, always check wiring prior to powering up system power supplies. MLIM-1; THERMOCOUPLE APPLICATION Thermocouple Connection: To utilize an MLIM-1 channel as a thermocouple input, configure that channel’s Interface Module Configuration Switch per Table 3... -4.
3... INTERFACE MODULES Thermocouple Application Notes: Cold Junction Compensation (CJC): For thermocouple measurements, the temperature of the terminal strip connections is required in the voltage to temperature conversion equation used by the OMP-MODL. This temperature is measured by the CJC sensor located in the MLAD-1 module. Any differential temperature from the metal terminal strip connections to the CJC sensor on the MLAD-1 circuit board will result in direct measurement errors.
3... INTERFACE MODULES To minimize noise pickup on sensor wiring between the OMP-MODL and the end sensor or signal source, 18 to 22 AWG shielded, twisted pair wire is recommended. Shielded Twisted Pair Line Terminal Strip 1 2 3 4 5 6 7 8 9 10 11 12 VDC-High Range Icon + ml141 Shield Figure 3...

3... INTERFACE MODULES In the event that a channel on a module quits responding with proper values, it may be an indication that this protective fuse has blown. The fuse can be removed from the circuit and checked for continuity with an ohm-meter and/or replaced with a Littelfuse P/N: 273.050 fuse available from Omega Engineering Incorporated or many electronic distributors.
3... INTERFACE MODULES MLIM-2; DIGITAL INTERFACE MODULE OVERVIEW Overview: The MLIM-2 Interface Module provides four input channels and four output channels on a single module. Each of the four input channels can be individually programmed for any combination of Event input, Count input, or Frequency input. The four output channels provide current limited nominal 5VDC output. Configuration of the module is done from within HyperNet in HyperWare.
3... INTERFACE MODULES module layer determined above. The switch bank should have only ONE switch ON and the other four switches OFF. CAUTION: The switch bank may have different numbering than the circuit board... insure that the marking on the circuit board is followed... not the marking on the switch banks. Hardware Input Configuration Switches: No hardware input configuration switches are provided on the MLIM-2.
3... INTERFACE MODULES implementation of a Counter channel within a Program Net and is covered in the Master Icon Listing, Appendix A. Channel input impedance is greater than 30K ohm. A 40mS debounce circuit can be enabled via software which can be used to filter out `contact bounce’ (see below).
3... INTERFACE MODULES CAUTION: Note that a direct connection exists between the common (-) terminal on all four channels of the MLIM2( Figure 3... -22). When connecting to multiple event or counter signal sources sharing a common ground or reference, insure that the source’s ground or reference is connected to the terminal strip `common’ terminal to prevent shorting out of the source signal and possible damage to the MLIM-2.
3... INTERFACE MODULES Frequency Signal Connection: To utilize an MLIM-2 channel as a Frequency input, connect the input signal positive lead to one of the four Input terminals (Chan A, B, C, or D) and the negative lead to one of the four Common terminals on the module terminal strip (Figure 3... -23). Note that all of the four Common terminals are interconnected and connect directly to the OMP-MODL circuit ground..
3... INTERFACE MODULES MLIM-2; DIGITAL OUTPUT APPLICATION The MLIM-2 provides four channels dedicated as outputs. These channels can be configured for functions such as alarming. The output is a current limited voltage signal with the voltage/current characteristics shown in Figure 3... -24.

Note that all of the four Common terminals are interconnected and connect directly to the OMP-MODL circuit ground.
3... INTERFACE MODULES MLIM-4; RTD / RESISTANCE INTERFACE MODULE OVERVIEW Overview The MLIM-4 is a four channel Interface Module for use in the OMP-MODL System Base. Each of the four channels can be individually programmed for any combination of RTD (100 ohm or 1000 ohm), Resistance or Thermistor input via the HyperWare software (HyperNet). Additionally, for RTD and resistance measurements, 2, 3, and 4-Wire configurations can be selected.

INTERFACE MODULES Each switch bank should have only ONE switch ON and the other four Module Address (Layer) Switch banks OFF - ON Module Module Module Module Module OFF - ON OFF - ON 2 3 4 5 6 ml051 Figure 3... -27: Example Address setting for Module Layer Position 4 switches OFF. CAUTION: The switch banks may have different numbering than the circuit board... insure that the marking on the circuit board is followed... not the marking on the switch banks.
3... INTERFACE MODULES MLIM-4; RTD INPUT APPLICATION The RTD function of the MLIM-4 allows for the input of Platinum RTD’s with any of the following characteristics: RTD Input ♦ 100 or 1000 ohm @ 0’ C ♦ European (0.0385) or American (0.0392) alpha coefficient curve ♦ 2, 3, or 4-wire configuration The actual temperature is calculated from the resistance and can be output in either degrees C or F. Two input temperature ranges are provided for maximizing span and ultimate resolution of the readings.
3... INTERFACE MODULES additive lead wire resistance can be ignored (eg in thermistor or Kohm resistance measurements). However, in applications of RTDs or lower resistance ranges this lead wire resistance can add up to substantial measurement errors... especially if long runs or lighter gauge lead wire is used. For example, in a 100 ohm RTD, 0.4 ohms of lead wire resistance would translates to a reading error of 1 Deg C.
3... INTERFACE MODULES 2-Wire Terminal Strip Connections: The MLIM-4 module is provided with a 12 position terminal strip. Each MLIM-4 input channel utilizes 3 of the 12 terminals (1-2-3, 4-56, 7-8-9, 10-11-12). Connect the input signal to the first two of the three input terminals (1-2, 4-5, 7-8, 10-11) on the terminal strip. A wire jumper must then be installed from the second to the third terminal (2-3, 5-6, 8-9, 11-12).
3... INTERFACE MODULES nearly the same level of error compensation as the 4-wire configuration with one less wire. Due to the fact that only one of the lead wires resistance is actually measured and the other lead wire is assumed to match, in using the 3-wire configuration, it is important that both lead wires used for the excitation current (connected to terminals 1 & 2, or 7 & 8 and opposite ends of the element) are of the same approximate length, same gauge, and operating at the same temperature.
3... INTERFACE MODULES 4-Wire Configuration The 4-wire configuration is used in applications where the lead wire effects calculated as above will have a significant error inducing effect on the resistance measurement. The 4-wire configuration provides the best compensation for lead wire resistance at the expense of running a 4th lead. The 4-wire configuration requires two input channels (A and B or C and D) to implement.

6... PCMCIA CARD CONFIGURATION AND USE 6... PCMCIA CARD CONFIGURATION AND USE OVERVIEW: The OMP-MODL utilizes the optional PCMCIA Card System to provide expanded data storage capacity within the OMP-MODL and/or to provide storage to a removable memory card that can be removed and transported to another location where the data is read from the card and saved into a file on the a PC.
6... PCMCIA CARD CONFIGURATION AND USE provide the necessary software interface between the PD-1drive and HyperWare. Also included are a number of utilities for use in formatting, copying etc on the PCMCIA card. PCMCIA CARD - EXPANDED MEMORY CAPACITY APPLICATION Hardware Configuration For applications using the PCMCIA card only for expanded memory capacity within the OMP-MODL, the only components required are the MLIM-5 and one or more memory cards (formatted for us with the OMP-MODL PCMCIA card system).
6... PCMCIA CARD CONFIGURATION AND USE CAUTION: If the memory card does not easily insert fully into the socket, double-check the orientation. The socket is designed to prevent full insertion with reversed orientation. For data storage on the memory card, the Write Protect switch must be in the disabled position (ie slid away from the WP mark) NOTE Numerous types of PCMCIA cards are currently available on the market utilizing various technologies.
6... PCMCIA CARD CONFIGURATION AND USE Installing the CardTalk Drivers: Follow the detailed instructions in the User’s Guide supplied with the drive. The installation process creates a directory called CardTalk and copies a number of files into it. It then modifies the AUTOEXEC.BAT and CONFIG.SYS files. A few additional comments on this installation process: ♦ Insure that the installation is done from DOS as specified ♦ Either the Express or the Custom Installation can be used.
6... PCMCIA CARD CONFIGURATION AND USE TIP: Upon boot of the PC with the standard drivers installed, the PD-1 will be assigned the next consecutive drive letter. For User’s requiring specific assignment of a drive letter to the PD-1 drive, the CONFIG.SYS file can be modified to force the PD-1 drive to be assigned to a particular drive letter. Refer to the Technical Support FAQ (frequently asked questions) sheet supplied with the drive for details.
6... PCMCIA CARD CONFIGURATION AND USE CAUTION Before inserting a PCMCIA card into the drive, touch the case of the PC or some other ground to discharge any static body charge. This step minimizes the chance of damaging the card by discharging your body static charge through the PCMCIA card connector. 1. Insert a formatted and prepared (as supplied by Omega Engineering Incorporated) PCMCIA card into the drive. Be sure that a card is inserted fully into the drive before testing. 2.
6... PCMCIA CARD CONFIGURATION AND USE PCMCIA Card Usage with HyperWare The PCMCIA card, in a transportable memory application is typically used to transfer collected data from a remotely located OMP-MODL to the PC and/or to transfer a new Program Net from the PC to a remotely located OMP-MODL.

8... POST-PROCESSING OF COLLECTED DATA 8... POST-PROCESSING OF COLLECTED DATA OVERVIEW Once data has been collected by the OMP-MODL and downloaded to a OMP-MODL Download file on the PC, a number of powerful data analysis and viewing options are available from within HyperWare. (See HyperComm, Chapter 5 for details on downloading data from the OMP-MODL).
8... POST-PROCESSING OF COLLECTED DATA A Post-Processing Net is constructed much the same way as a Program Net is developed within HyperNet. The main difference is that a Program Net running in a Figure 8... 1 OMP-MODL receives its data from various hardware channels such as thermocouples, then saves the collected data to OMP-MODL memory. In contrast, Post-Processing Net receives its data from a OMP-MODL Download file, processes the data, then saves the data in a destination file format. Figure 8...

10... HYPERT RACK™ REAL-TIME DATA DISPLAY 10... HYPERTRACK™ REAL-TIME DATA DISPLAY OVERVIEW The OMP-MODL in conjunction with a PC running HyperWare is capable of operating in a real-time mode called HyperTrack or tracking. HyperTrack provides a real-time graphic trending and/or scrolling numerical display on the connected PC screen of values received from a serially connected OMP-MODL. Figure 10... -1 shows real-time tracking in the HyperTrack window.
10... HYPERT RACK™ REAL-TIME DATA DISPLAY 2. From within HyperTrack, construct a real-time HyperTrack Net. (Note that this is a different Net than the Program Netuploaded into the OMP-MODL memory. The HyperTrack Net runs on the PC) 3. Establish the serial connection between the PC and the OMPMODL 4. Enable real-time tracking CONSTRUCTING A OMP-MODL PROGRAM NET FOR HYPERTRACK Figure 10...
10... HYPERT RACK™ REAL-TIME DATA DISPLAY CONSTRUCTING A HYPERTRACK NET During a real-time tracking session, the OMP-MODL transmits values of the Probe Point icons to the PC via the serial link. These values are then processed through a HyperTrack Net running on the PC (in the HyperTrack window) and displayed. HyperTrack Nets provide a means to perform additional processing of values from Probe Point icons before they are displayed.
10... HYPERT RACK™ REAL-TIME DATA DISPLAY Program Net that contains the desired Probe Point icons. The OMP-MODL may be in either the Enabled or Stopped mode. 2. From the HyperComm Window, click and drag the Program Net icon on the OMP-MODL to the PC and release it. The Program Net and Probe Point icon information will be automatically downloaded to the PC and a Probe Point icon will display overlaying the image of the PC.
10... HYPERT RACK™ REAL-TIME DATA DISPLAY 3. The OMP-MODL connection can then be disconnected (eg to save long distance charges if connected via modem) while the HyperTrack Net is developed. Reading Probe Point icons from a Program Net on disk: If a copy of the Program Net that will be running in the OMP-MODL during tracking is available on disk, this Program Net can be opened from disk and the Probe Point icon information will be available for HyperTrack Net development.
10... HYPERT RACK™ REAL-TIME DATA DISPLAY MATH ICON The Math icon provides algebraic processing of data as it passes from input to output. In Figure 10... -3 above, the Math icon is providing a differential temperature calculation and generating a third data channel, Tdelta which is then displayed as well as stored to file. Figure 10... 7: Math icon FILE ICON The File icon represents storage to file of all signals connected to its inputs.
10... HYPERT RACK™ REAL-TIME DATA DISPLAY Saved HyperTrack Nets should only be used for real-time tracking with OMP-MODLs configured with Program Nets that contain matching Probe Point icons. If mismatched nets are used, channels may be incorrectly titled and displayed in incorrect sequence. For example: A HyperTrack Net is developed and saved for use with a OMP-MODL Program Net that includes 3 Probe Point icons labeled A, B, and C.
10... HYPERT RACK™ REAL-TIME DATA DISPLAY Data Buffer As new data is collected, older data will be scrolled down one line. Older data is still accessable after it has scrolled out of the window by clicking on the scroll bar buttons on the right side of the window. HyperTrack Trending Display Window During real-time tracking, data from the signals connected to the Trending Display icon is displayed in a multi-pen horizontal format in the pop-up Trending Display window.
10... HYPERT RACK™ REAL-TIME DATA DISPLAY Trending Configuration Dialog By double-clicking anywhere on the Trending Display Window, a Configuration Dialog is displayed (Figure 10... -12). This dialog allows for various User settings for the data display. Figure 10... -12: Real Time Trending Configuration dialog NOTE: After changing any of the following settings, the Tracking session must be Stopped (click on the Stop Sign Button) and restarted (Green Flag).
10... HYPERT RACK™ REAL-TIME DATA DISPLAY Channel Ranges The data channels are scaled and plotted per a single amplitude axis on the left edge of the plot. Upon start of a Trend Tracking session, the range for all channels defaults to +/-1000. A Min. and Max. value for each channel can be set by editing the appropriate text boxes. If all of the channels have the same Min/Max values, then the vertical axis will reflect this range.
10... HYPERT RACK™ REAL-TIME DATA DISPLAY STOPPING A HYPERTRACK SESSION Figure 10... 15: Stop Tracking button To stop a real-time tracking session, click on the Stop button. Stopping a tracking session does not stop execution of the Program Net within the OMP-MODL, it merely commands the OMP-MODL to stop sending Probe Point values to the PC. When a HyperTrack session is stopped, the files associated with any connected File icons are closed and the update of data to the Scrolling Display window stops.

APPENDIX C: HYPERWARE FILE LISTING Tank Level / Inventory Profiling Data Collection with Alarming: A remote site liquid tank has a constantly varying inventory as liquid is added and removed over time. Profiling of the inventory over time, onsite display of the inventory amount, and overflow telephone pager alarming are all desired. Using a single 4-20mA pressure transmitter input and a Math icon, the inventory can be calculated in gallons.
11.. . APPENDIX C: HYPERWARE FILE LISTING High Speed Thermocouple Application: In some applications, maximum speed of thermocouple measurement is desired. The Thermocouple icon is one of the slowest to process in a Program Net due to the intensive math associated with each sample. A Cold Junction Compensation reading is required as well as the thermocouple reading, then the two are combined through curve approximating polynomials... heavy math for the OMP-MODL.
11.. . APPENDIX C: HYPERWARE FILE LISTING This Post-Processing Net combines the voltage data from the thermocouple input channels and the CJC readings (in ohms) to calculate the actual temperature of each of the three thermocouple channels and store the data in a new destination file called BRAKETST.HLD. This special calculation is done using the function TC_J(X,Y) in each of the three Math icons.
