Preface Use this manual if you are responsible for designing, installing, programming, or troubleshooting control systems that use Compact I/O and/or MicroLogix 1500 or CompactLogix controllers. Packaged Controller Functionality Both the 1769-L24ER-QBFC1B and 1769-L27ERM-QBFC1B packaged controllers provide the same high-speed counter (HSC) functionality as the 1769-HSC except for the input frequency.
Preface Notes: 10 Rockwell Automation Publication 1769-UM006E-EN-P - July 2013
Chapter 1 Module Overview The 1769-HSC module is an intelligent counter module with its own microprocessor and I/O that is capable of reacting to high-speed input signals. The module can interface with up to two channels of quadrature or four channels of pulse/count inputs. The signals received at the inputs are filtered, decoded, and counted. They are also processed to generate rate and time-between-pulses (pulse interval) data.
Chapter 1 Module Overview Counters The module is capable of counting pulses in either direction (forward, reverse, up, down). A maximum of four pulse counters (or two quadrature counters) are available. Each 32-bit counter can count to ±2 billion as a ring or linear counter. In addition to providing a count value, the module provides a rate value up to ±1 MHz, dependent upon the type of input (the L23 packaged controller’s HSC module functionality does not provide rate values).
Module Overview Hardware Features Chapter 1 The module’s hardware features are illustrated in Figure 1. Refer to Chapter 3 on page 45 for detailed information on installation and wiring. For information about the packaged controllers’ hardware features, see the CompactLogix Packaged Controllers Quick Start and User Manual, publication IASIMP-QS010.
Chapter 1 Module Overview Status Indicators The front panel of the 1769-HSC module has a total of 12 status indicators. For information about the packaged controllers’ status indicators, see the CompactLogix Packaged Controllers Quick Start and User Manual, publication IASIMP-QS010.
Chapter 2 Module Operation This chapter details the operation of the 1769-HSC module. We strongly suggest that you review this information before configuring your module.
Chapter 2 Module Operation Module Operation Block Diagrams To provide an overview of the module operation, the block diagrams indicate relationships between module functions and configuration parameters. Inputs The following diagram illustrates how the inputs function. Input Filtering Discrete Input State Decoded NumberOfCounters Operational Mode Pulse Direction DirInvert DirInhibit Count Min/Max and Linear/Ring Overflow (ResetOvf)(1) Underflow (ResetUdf)(1) Store CtrnConfig.
Module Operation Chapter 2 Outputs The following diagram illustrates how the outputs function.
Chapter 2 Module Operation Number of Counters The module has six input points: A0, B0, Z0, A1, B1, and Z1. Through these inputs, the module can function with 1, 2, 3, or 4 counters depending upon the number of counters and the operational mode configuration of the input points. Summary of Available Counter Configurations The table summarizes the input configurations available for all counters, based on the number of counters. No.
Module Operation Chapter 2 The counter options and operating modes are summarized in Figure 2.
Chapter 2 Module Operation Input Filtering In many industrial environments, high frequency noise can be inadvertently coupled to the sensor wires. The module can help reject some noise by means of built-in filters. Inputs are filtered by means of user-selectable, low-pass filters(1) set up during module configuration. The available nominal pulse width filters are shown in the table. Input Filter A0, A1, B0, B1, Z0, Z1 5 ms, 500 s, 10 s, no filter (7.1 ms, 715 s, 18.
Module Operation Operational Mode Selection Chapter 2 A count channel’s operational mode configuration selection determines how the A and B inputs cause a counter channel to increment or decrement.
Chapter 2 Module Operation Pulse/External Direction Mode Selection In this mode, the B input controls the direction of the counter, as shown in Figure 3. If the B input is low (0), the counter increments on the rising edges of input A. If the input B is high (1), the counter decrements on the rising edges of input A. Two Output Control bits let you modify the operation of the B input from your control program or during configuration.
Module Operation Chapter 2 Table 2 - Pulse External Direction Counting Direction Inhibit Bit Direction Invert Bit Input A (count) Input B (direction) Change in Count Value 0 0 0 or open 1 1 -1 0, 1, Don’t care 0 0 or open -1 1 1 0, 1, Don’t care 0 0 or open 1 1 1 0, 1, Don’t care 0 0 or open -1 1 -1 0, 1, Don’t care 0 0 1 1 1 0 1 See Direction Inhibit and Direction Invert Output Control Bits on page 21 for more information.
Chapter 2 Module Operation Up and Down Pulses Mode Selection In this mode, the counter channel increments on the rising edge of pulses applied to input A and decrements on the rising edge of pulses applied to input B. When set, the Direction Inhibit bit causes both A and B to increment. When set, the Direction Invert bit causes B to increment and A to decrement. When the Direction Invert and Direction Inhibit bits are both set, both A and B decrement.

Chapter 2 Module Operation Input Frequency Counter Types Maximum input frequency is determined by the input configuration as shown in the table.
Module Operation Chapter 2 Ring Counter Figure 8 demonstrates ring counter operation. In ring counter operation, the current count (Ctr[n].CurrentCount) value changes between user-programmable minimum count (CtrnMinCount) and maximum count (CtrnMaxCount) values. If, when counting up, the counter reaches the CtrnMaxCount value, it rolls over to the CtrnMinCount value upon receiving the next count and sets the overflow bit.
Chapter 2 Module Operation Counter Enable/Disable The counter can be enabled or disabled using the CtrnEn control bit. Be aware that disabling the counter does not inhibit any current count loading functions (for example, preset or direct write) or any Z function. Z Input Functions There are three Z input functions: store, gate, and Z preset. Store The Z-input can be used to capture the current count value even when the counter is counting at full 1 MHz speed.
Module Operation Chapter 2 Preset/Reset Preset sets the counter to a zero or non-zero value you define. Reset the counter by setting this value (CtrnPreset) to zero. Counter Reset Refer to page 73 in Chapter 4 for details on performing a default counter reset for the CMX 5370 L2 packaged controller and the 1769-HSC/B module only. The L23E packaged controller and the 1769-HSC/A module do not have this functionality.
Chapter 2 Module Operation Rate/Timer Functionality To ensure maximum accuracy, the module offers two different methods to calculate the rate. • Per Pulse = 1/Pulse Interval • Cyclic = Number of Pulses/User-defined Time Interval You select the method used, depending upon the pulse speed as defined below. These are continuously available regardless of input operational mode. IMPORTANT The Rate/Timer Functionality information does not apply to the L23E packaged controller.
Module Operation Chapter 2 The generalized rate calculation is Rate = count/ time. IMPORTANT The rate calculation is based on net counts. If a counter goes up 500 counts and down 300 counts, the net count is 200. Therefore, changes in direction and speed affect the Ctr[n].CurrentRate value. The cyclic method is better suited to high pulse rates.
Chapter 2 Module Operation Scalar You can configure the CtrnScalar value to scale or convert the raw rate value to application-specific information, such as RPM (Revolutions Per Minute). Setting CtrnScalar to 1 leaves the rate value in cycles per second (Hertz). The actual rate equation is the following. Current Rate = TIP 1000 x count CyclicRateUpdateTime x Scalar To configure the Ctr[n].CurrentRate value to show an RPM value, set CtrnScalar to (counts per revolution)/60.
Module Operation Chapter 2 Rate Method Selection By knowing when to use each method, an optimal rate determination can be made. TIP Fractional rates are not reported by the module, but can be calculated from Ctr[n].PulseInterval in your control program. Use the following information to choose the appropriate calculation method. In general, consider the effect of having the count off by ±1 in each method at frequencies of interest to see if the resulting inaccuracy is acceptable.
Chapter 2 Module Operation Output Control All 16 outputs can be controlled by any of the four counters or by the user’s control program, via the output mask function. Output states are determined by count, rate (not supported in packaged controller), ranges, mask configuration data, overcurrent status, and safe state settings and conditions. The 16 outputs are made up of four real (physical) outputs and 12 virtual outputs. The status of the real and virtual outputs is available to the user program.
Module Operation Chapter 2 Ranges For the 1769-HSC module and the embedded HSC in the CMX 5370 L2 packaged controllers, up to 16 dynamically configurable ranges are available. Ranges activate outputs based on the current count value or the current rate value. Each range is programmed with a type, counter number, two limit values, an invert bit, and an output mask. For the embedded HSC in the L23E packaged controller, up to four dynamically configurable ranges are available.
Chapter 2 Module Operation Count Range In a non-inverted count range, the outputs are active if the count value is within the user-defined range. In an inverted count range, the outputs are active if the count value is outside the user-defined range. Valid limits for the range are -2…2 billion regardless of programmed minimum and maximum values. Figure 9 shows all ranges referring to one counter. The module is capable of individually assigning each range to any counter.
Module Operation Chapter 2 Rate Range IMPORTANT The Rate Range information does not apply to the packaged controller. In a non-inverted rate range, the outputs are active if the rate measurement is within the user-defined range. In an inverted rate range, the outputs are active if the rate measurement is outside the user-defined range. The input rate can be up to 1 MHz in either direction. Figure 10 shows all ranges referring to one counter.
Chapter 2 Module Operation Overcurrent If the module detects a real output point overcurrent condition, it reports it to the input file and turns off that output. You can also program the module to latch each of the four real outputs off, emulating a physical fuse, or to automatically reset. The 12 virtual outputs do not have this function.
Module Operation Chapter 2 Program State Run (PSR) Program State Run lets you specify that the output should continue to be controlled by the module as if it were in the Run state. That is, events on the module or changes in the output image will affect the physical outputs without regard to the Program_HLS or UDSS state indicated. When this bit is set, the corresponding OutnProgramMode and OutnProgramValue bits are ignored.
Chapter 2 Module Operation Fault State Run (FSR) Similar to Program State Run, Fault State Run lets you specify, on a bit basis, that the output should continue to be controlled by the module as if it were Run state. That is, events on the module or changes in the output image will affect the physical outputs without regard to the Fault_HLS or UDSS state indicated. When this bit is set, the corresponding Fault mode and fault value bits are ignored.
Module Operation Chapter 2 Program to Fault Enable (PFE) The ProgToFaultEn bit lets you select which data value (Program Value or Fault Value) to apply to the output when the Output State Logic state Prog_HLS changes to indicate Fault_HLS. If PFE is 0, the module leaves the Program value applied. If PFE is set to 1, the Fault value is applied.
Chapter 2 Module Operation Table 11 illustrates the step-by-step logical operations that are performed to determine the final output state. For example, Range 1 values do not affect the output because Range 1 is disabled, and the Output Off Mask causes some of the outputs to change to zero because it takes priority over the range masks. The output parameters shown have been discussed in the previous sections.

Informations sur l’utilisation de cet équipement en environnements dangereux. Products marked "CL I, DIV 2, GP A, B, C, D" are suitable for use in Class I Division 2 Groups A, B, C, D, Hazardous Locations and nonhazardous locations only.
Installation and Wiring Power Requirements Chapter 3 The modules receive power through the Compact bus interface from the 5V DC/24V DC system power supply. The maximum current drawn by the modules is shown in the table. Module Current Draw 5V DC 24V DC 425 mA 0 mA WARNING: When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations.
Chapter 3 Installation and Wiring Protect the Circuit Board from Contamination The printed circuit boards of the modules must be protected from dirt, oil, moisture, and other airborne contaminants. To protect these boards, we recommend installing the system in an enclosure suitable for the environment. Keep the interior of the enclosure should clean and the enclosure door closed whenever possible. Power Supply Distance You can install as many modules as your power supply can support.
Installation and Wiring System Assembly Chapter 3 The module can be attached to an adjacent controller, power supply, or I/O module. For mounting instructions, see Panel Mounting on page 50, or DIN Rail Mounting on page 52. To work with a system that is already mounted, see Replace the Module within a System on page 53. Refer to the illustration when assembling the Compact I/O system. A D E C B G B F 45275 1. Disconnect the power. 2.
Chapter 3 Installation and Wiring Mount the Module Use these procedures to mount your module. ATTENTION: During panel or DIN-rail mounting of all devices, be sure that all debris (metal chips, wire strands) is kept from falling into the module. Debris that falls into the module could cause damage at powerup. Minimum Spacing Maintain spacing from enclosure walls, wireways, adjacent equipment, and so forth. Allow 50 mm (2 in.) of space on all sides for adequate ventilation, as shown.

Chapter 3 Installation and Wiring Panel Mounting Procedure By Using Modules as a Template This procedure lets you use the assembled modules as a template for drilling holes in the panel. Due to module mounting hole tolerance, it is important to follow these procedures: 1. On a clean work surface, assemble no more than three modules. 2. Using the assembled modules as a template, carefully mark the center of all module-mounting holes on the panel. 3.
Installation and Wiring Replace the Module within a System Chapter 3 The module can be replaced while the system is mounted to a panel or DIN rail. 1. Remove power, referring to the Warning on page 47. 2. Remove terminal block or disconnect input and/or output wiring from the module. 3. Remove the upper and lower mounting screws from the module (or open the DIN latches using a screwdriver). 4.
Chapter 3 Installation and Wiring Field Wiring Connections Consider these system wiring guidelines when wiring your system. General Guidelines • Make sure the system is properly grounded. • Input and output channels are isolated from the 1769 Compact bus. Input channels are isolated from one another; output channels are not. • Shielded cable is required for high-speed input signals A, B, and Z. Use individually shielded, twisted-pair cable for lengths up to 300 m (1000 ft).
Installation and Wiring Chapter 3 Considerations for Reducing Noise In high-noise environments, the 1769-HSC module inputs can accept ‘false’ pulses, particularly when using low frequency input signals with slowly sloping pulse edges. To minimize the effects of high frequency noise on low frequency signals, perform the following: • Identify and remove noise sources. • Route input cabling away from noise sources. • Use your programming software to select low-pass filters on input signals.
Chapter 3 Installation and Wiring Follow these steps. 1. Loosen the terminal screws to be wired. 2. Route the wire under the terminal pressure plate. You can use the bare wire or a spade lug. The terminals accept a 6.35 mm (0.25 in.) spade lug. TIP The terminal screws are non-captive. Therefore, it is possible to use a ring lug (6.35 mm (0.25 in.) maximum outside diameter with 3.53 mm (0.139 in.) minimum inside diameter) with the module. 3.
Installation and Wiring Chapter 3 Wire the Modules After the module is properly installed, wire the modules by using this procedure. To provide proper operation and high immunity to electrical noise, always use shielded wire. ATTENTION: To prevent shock hazard, care should be taken when wiring the module to signal sources. Before wiring any module, disconnect power from the system power supply and from any other source to the module. Do not wire more than two conductors on any single terminal.
Chapter 3 Installation and Wiring Terminal Door Label A removable, write-on label is provided with the module. Remove the label from the door, mark the identification of each terminal with permanent ink, and slide the label back into the door. Your markings (ID tag) will be visible when the module door is closed. Terminal Block Wiring The input and output terminals are shown below. Both inputs and outputs are isolated from the 1769 Compact bus.
Installation and Wiring Chapter 3 Wire Diagrams The following pages show wiring examples for a differential encoder, single-ended encoder, and discrete device. Inputs The module utilizes differential inputs. Therefore, two input terminals are required for each input point. For example, the A0+ and A0- terminals are required for input point A0. Each input point is isolated from other input points, the 1769 Compact bus, and the entire output terminal group.

The pull-up resistor (R) value depends on the power supply value.
Chapter 3 Installation and Wiring Outputs The four output terminals must be powered by a user-supplied external source. User-power range is from 5…30V DC. See the Output Specifications in Appendix A on page 124. There is no isolation between the outputs, but the outputs are isolated from the inputs and the 1769 Compact bus. Electronic Protection The electronic protection of the 1769-HSC module has been designed to provide protection for current overload and short-circuit conditions.
Installation and Wiring Chapter 3 Transistor Output Transient Pulses The maximum duration of the transient pulse occurs when minimum load is connected to the output. However, for most applications, the energy of the transient pulse is not sufficient to energize the load. ATTENTION: A transient pulse occurs in transistor outputs when the external DC supply voltage is applied to the output common terminals (for example, via the master control relay).
Chapter 3 Installation and Wiring Output Wiring Basic wiring(1) of output devices(2) to the module is shown in Figure 18. ATTENTION: Follow these guidelines: • Miswiring of the module to an AC power source or applying reverse polarity will damage the module. • Be careful when stripping wires. Wire fragments that fall into a module could cause damage at powerup. Once wiring is complete, make sure the module is free of all metal fragments.
Chapter 4 Module Configuration, Output, and Input Data After installing the 1769-HSC module, you must configure it for operation by using the programming software compatible with the controller, such as RSLogix 500 or RSLogix 5000 software. TIP Normal counter configuration is done using programming software. In that case, it is not necessary to know the meaning of the bit location. However, some systems let the control program change configuration.
Chapter 4 Module Configuration, Output, and Input Data Configuration Array The configuration array, which consists of 118 words (46 words for the packaged controller), lets you specify how the module’s counters will function.

Module Configuration, Output, and Input Data Chapter 4 Counter Reset (CtrReset) Bits 12…15 in the configuration array correspond to the counter reset selection bits for counters 0…3, respectively. The Counter Reset Enable in the Add-On profile lets you select which counter to be enabled or disabled. An enabled checkbox indicates a zero (0) in the respective counter reset selection bits in RSLogix 5000 software.
Chapter 4 Module Configuration, Output, and Input Data Figure 20 - Configuration for Individual Counter Reset Disable Counter 0 in this example equates to individual counter reset selection bit 12. As shown in Figure 20, the Counter Reset Enable box has been unchecked to indicate the individual counter reset functionality is disabled for the selected counter of the 1769-HSC/B module. The corresponding controller tag in RSLogix 5000 software shows a one (1) for disabled.
Module Configuration, Output, and Input Data Chapter 4 PFE - Program to Fault Enable (ProgToFaultEn) This bit indicates what should happen when the bus controller indicates a change from one condition (Program mode) to another (Fault mode). If this bit is set (1), the safe state operation of all four real outputs changes to that identified by the Fault State and Fault Value words.

Chapter 5 Diagnostics and Troubleshooting This chapter describes how to troubleshoot the module. Safety Considerations Topic Page Safety Considerations 109 Module Operation versus Counter Operation 111 Counter Defaults 111 Module Diagnostics 112 Non-critical versus Critical Module Errors 113 Module Error Definition 114 Error Codes 116 Safety considerations are an important element of proper troubleshooting procedures.
Chapter 5 Diagnostics and Troubleshooting Stand Clear of the Machine When troubleshooting any system problem, have all personnel remain clear of the machine. The problem could be intermittent, and sudden unexpected machine motion could occur. Have someone ready to operate an emergency stop switch in case it becomes necessary to shut off power to the machine.
Diagnostics and Troubleshooting Module Operation versus Counter Operation Chapter 5 The module performs operations at two levels: • Module level • Counter level Module-level operations include functions, such as powerup, configuration, and communication with a bus master, such as a MicroLogix 1500 controller. Counter-level operations include counter-related functions, such as data conversion and overflow or underflow detection. Internal diagnostics are performed at both levels of operation.
Chapter 5 Diagnostics and Troubleshooting IN OUT Module Diagnostics 0 2 FUSE 1 3 OK A0 B0 The 176-HSC module offers power-up, configuration, and post configuration diagnostics. Power-up Diagnostics At module powerup, a series of internal diagnostic tests are performed. These diagnostic tests must be successfully completed or the OK status indicator remains off and a module error results and is reported to the controller.
Diagnostics and Troubleshooting Chapter 5 Configuration Diagnostics When a configuration is sent, the module performs a diagnostic check to see that the configuration is valid. This results in either a valid ModConfig bit or module configuration error. See the Configuration Error Codes table on page 117 for configuration error codes. Post Configuration Diagnostics If the ModConfig bit in the input array is set, then the module has accepted the configuration.
Chapter 5 Diagnostics and Troubleshooting Module Error Definition Module errors are expressed in two fields as four-digit Hex format, with the most significant digit as ‘don’t care’ and irrelevant. The two fields are ‘Module Error’ and ‘Extended Error Information’. The structure of the module error data is shown in Table 19.
Diagnostics and Troubleshooting Chapter 5 Configuration Errors If you set the fields in the configuration file to invalid or unsupported values, the module ignores the invalid configuration, generates a non-critical error, and keeps operating with the previous configuration. The Configuration Error Codes table on page 117 lists the possible module-specific configuration error codes defined for the module. Correct the error by providing proper configuration data to the module.
Chapter 5 Diagnostics and Troubleshooting Error Codes The tables in this section explain the extended error codes for general common hardware errors, configuration errors, and runtime errors.

Chapter 5 Diagnostics and Troubleshooting The BadModConfigUpdate error conditions are shown in the following table. They occur when you attempt to change a forbidden module configuration parameter while a counter or range is still enabled. To recover from this situation, do the following: • Correct the configuration problem. • Reconfigure the module. Refer to your controller’s documentation for available reconfiguration methods.

For definitions of terms not listed here, refer to the Allen-Bradley Industrial Automation Glossary, publication AG-7.1. accumulated value (ACC) The number of elapsed time intervals or counted events. actuator 1) A device that converts an electrical signal into mechanical motion. 2) In a general sense, any machine/process load device (for example, transducer) of a controller output circuit. See output device (page 162).
Glossary broadband link 1) A communication link that can have multiple channels. Each channel signal modulates its own carrier frequency. Example: LAN/1 link. 2) Contrasted with carrier-band link (page 158) and baseband link (page 157). bus A single path or multiple parallel paths for power or data signals that several devices can be connected at the same time. A bus can have several sources of supply and/or several sources of demand.
Glossary coordinated system time (CST) Timer value which is kept synchronized for all modules within a single ControlBus chassis. The CST is a 64-bit number with s resolution. data 1) A general term for any type of information. 2) In a more restricted sense, data refers to the end-use information in the particular context; thereby excluding the protocol information used to get the end-use information.
Glossary electronic keying A system feature which makes sure that the physical module attributes are consistent with what was configured in the software. encoder Any feedback element that converts linear or rotary position (absolute or incremental) into a digital signal. • Linear encoder—is a feedback element that directly converts linear position (absolute or incremental) into a digital signal.
Glossary intelligent I/O module 1) An I/O module that provides some on-board processing of input values to control some output values without going through the data table for control by the ladder logic. An intelligent I/O module can have digital I/O circuits, analog I/O circuits, or both. 2) Contrasted with direct I/O module (page 159). interval 1) The length of time between events or states. For example, the length of time between when a signal is high can be described as the interval between pulses.
Glossary node The connection point at which media access is provided. output device 1) For a computer, a CRT terminal or printer. 2) For a programmable controller, see actuator (page 157). owner-controller The controller that creates and stores the primary configuration and communication connection to a module. period 1) The length of time for a cyclical operation to complete one full cycle.
Glossary removal and insertion under power ControlLogix feature that lets a user install or remove a module or RTB while (RIUP) power is applied. requested packet interval (RPI) A configured parameter that defines when the module will multicast data. run mode In this mode, the controller program is executing.
