Chapter 1 Module Overview This chapter contains the following: • high-speed counter module overview • operating modes • hardware features High-Speed Counter Module Overview The High-Speed Counter Module, catalog number 1746-HSCE is an SLC 500 family compatible device except with the 1747-ASB Remote I/O Adapter Module. The high-speed module can be used with SLC 5/02 (and above) processors. The module’s bidirectional counting ability allows it to detect movement in either direction.
1-2 Module Overview Module operation is determined by selections made in the Setup and Control Word (M0:e.1). Setting the Function Control bit to 1 triggers the module to start the proper pulse counter, rate measurement, and output control functions. Many parameters are dynamic and can be changed without disrupting counter operation. A block diagram of the module is shown below. Inputs from the terminal block enter the diagram at the left, outputs to the terminal block exit at the right.
Module Overview Operating Modes 1-3 The module operates in 3 modes: • Range mode • Rate mode • Sequencer mode Specific operating mode information is contained in Chapter 2, Module Operation. The following information summarizes the module’s operating modes. IMPORTANT Appendixes D and E contain blank worksheets to assist you when configuring your module. Appendix D contains worksheets for Range and Rate Mode operation. Appendix E contains worksheets for the Sequencer Mode operation.
1-4 Module Overview Sequencer Mode In the Sequencer Mode, you define a sequence of presets and a series of corresponding output patterns. When the Accumulated Count passes the next preset, the outputs are updated to the corresponding pattern.
Module Overview 1-5 LEDs These LEDs illuminate when their corresponding input or output is active: • • • • LEDs 0-3 correspond to Physical Outputs 0-3. LEDs 4-7 correspond to Soft Outputs 4-7. LEDs A, B, Z, and LS indicate the input is energized. LED FAULT illuminates when the module is faulted. Input and Output Terminals These terminals supply power and inputs to the module and outputs to the attached output devices. They can accommodate two 14 AWG wires.
1-6 Module Overview Jumper JW1 JW1 selects the filtering rate used to debounce the limit switch input. Filtering rates are 300 µs and 10 ms. See Chapter 3 for default jumper setting.
Chapter 2 Module Operation This chapter describes the basic operation of the module. Specific programming information and individual memory maps for each mode are contained in Chapter 4.
2-2 Module Operation The above sources are determined by the Operating Mode and the Output Source Select fields. Module operation is determined by user-defined configuration parameters. Setting the Function Control bit to 1 starts the proper pulse counter, Rate Measurement, and output control functions. Dynamic parameters can be changed regardless of the Function Control bit. Static Parameters can be changed only when the Function Control bit is reset (to 0).
Module Operation Pulse and Direction Input 2-3 In this configuration, count pulses are applied to input A. The counter direction is controlled by either the Up/Down Count Direction bit, or by an external signal applied to input B (depending on the selection made in M0:e.1/9-11). When Pulse and Direction with External Control is chosen, the B input controls the direction (as illustrated below). If input B is low, the counter increments on the rising edges of input A.
2-4 Module Operation The count direction can be controlled from your user program rather than using a control signal connected to input B. This can be accomplished with the Up/Down Count Direction bit (M0:e.1/3) as follows: Up/Down Count Direction – bit 3 Up/Down Count Direction bit Bit Number (decimal) 15 14 13 12 11 10 9 8 Setup and Control Word, Word 1 7 6 5 4 3 2 1 0 M0:e.
Module Operation Quadrature Encoder Input 2-5 The figure below shows a quadrature encoder connected to inputs A, B, and Z. The count direction is determined by the phase angle between input A and input B. If A leads B, the counter increments. If B leads A, the counter decrements. The counter resolution can be selected so that the count increments/ decrements on one edge of input A only (X1), on both edges of input A (X2), or on both edges of input A and input B (X4).
2-6 Module Operation Up/Down Pulse Inputs With this input type, the counter increments on the rising edge of pulses applied to input A and decrements on the rising edge of pulses applied to input B. If pulses are applied to inputs A and B simultaneously, the pulse counter retains its previous value. The counter can be reset as described in Counter Reset Control on page 2-9. IMPORTANT Specific wiring information is contained in Chapter 3.
Module Operation Input Pulse Counter 2-7 The module’s input pulse counter has the ability to count input pulses at a rate of up to 50k Hz. Several types of channel A and B input configurations are supported as discussed previously. The resulting Accumulated Count value is available in the module’s Input Data File. Counter Types The module provides two types of counter operation, ring and linear. The selection is made by the Counter Type bit (M0:e.
2-8 Module Operation IMPORTANT If the reset value is nonzero, there is a delay of up to 500 µs before the reset value is loaded. Count pulses can be lost if they happen during the delay time. Refer to Timing Information in Appendix A. Ring Counter The figure below demonstrates ring counter operation. In ring counter operation, the count value goes between 0 and a maximum value. The maximum value must be entered in the Maximum Count Value (M0:e.34 Range and Rate Mode, M0:e.41 Sequencer Mode).
Module Operation 2-9 Counter Reset Control Reset Mode (bits 5,6,7) allows you to select the Accumulated Counter reset conditions. If the pulse counter is reset, the rate calculation is not affected. Bit 5 enables the Z reset, Bit 6 enables the limit switch reset, and bit 7 enables the Soft Reset. The counter can be reset from any combination of the Z input, LS input, or Soft Reset bit (M0:e.1/4). In the Sequencer Mode, you can reset the sequencer to the Initial Output pattern (M0:e.
2-10 Module Operation The reset of the counter is edge triggered. It occurs only when all of the conditions specified become true. If multiple conditions are selected, the counter is reset on the last event’s 0 to 1 transition. For example, if Z and LS are selected (011), Z by itself will not trigger the reset. Z and LS must both be ON. IMPORTANT The time it takes for the counter to reset depends upon the value it resets to.
Module Operation 2-11 Pulse Counter State When the SLC processor enters run or test mode, the Accumulated Count is reset to 0. It is held at 0 until the user program completes module configuration and the Function Control bit is set to 1. If the Function Control bit is reset to 0, the counter will again be reset and held at 0 until the Function Control bit returns to 1. The counter state is available to the user program in the Pulse Counter State field (I:e.0/14-15).
2-12 Module Operation Rate Measurement Calculation The module calculates the Rate Measurement by counting pulses in a fixed interval of time. You enter the fixed interval in the Rate Period parameter. This value is set in increments of 10 ms, from 10 ms to 2.55 seconds. The number of pulses counted in the interval is made available in the Rate Period Count word (I:e.2). Pulses increment or decrement the count.
Module Operation 2-13 Selecting the Rate Period Parameter The Rate Period parameter defaults to 0 and must be set to a value between 1 and 255 (10 ms to 2.55 seconds) to avoid a configuration error. Consider the following when selecting the Rate Period: • Make sure your Rate Period does not allow a Rate Counter Overflow to occur. This will depend on the maximum pulse frequency and input type.
2-14 Module Operation Output Control Physical and Soft Outputs The module provides 4 physical outputs. You select whether these outputs are to be activated from the user program or from the module in response to specified input events (refer to Output Source Select M0:e.0/0-7). The states of these 4 Physical Outputs are available to the user program in the Output Status field (I:e.4/8-11). In addition to the Physical Outputs, 4 Soft Outputs are available.
Module Operation 2-15 Range Outputs - Range and Rate Mode Physical Output patterns Bit Number (decimal) 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Range 2 and 1 Outputs, Word 3 M0:e.3 M0:e.4 M0:e.5 M0:e.6 M0:e.7 M0:e.
2-16 Module Operation Output Start Up and Enabling When the SLC processor is not in run mode, the module outputs are disabled. After the SLC processor enters run mode, the module examines the Direct Output fields (O:e.0/0-7). All outputs under module control are disabled until after the module configuration has been completed and the Function Control bit has been set to 1. If the Function Control bit is returned to 0 the module controlled outputs will again be disabled.
Module Operation 2-17 Range Mode In the Range Mode, you use the counter ranges to specify the outputs to be active within each range. Ranges may overlap. The ranges are defined using the Starting and Ending Values (M0:e.10-33). The Range Outputs fields (M0:e.3-8) contain the output patterns that specify which outputs are active. Output patterns are applied to the Output Status field (I:e.4/8-15) and output terminals when the count is within the associated range (i.e.
2-18 Module Operation In this example, four ranges are specified. Configuration data for the counter is shown in the table. It indicates that output 0 is on for counts within range 1, output 1 is on for counts within range 2, output 2 is on for counts within range 3, and both outputs 0 and 3 are on for counts within range 4. When the count is 2000, outputs 2 and 1 are on, since 2000 falls within ranges 2 and 3. The figure below demonstrates Range Mode when a ring counter is used.
Module Operation 2-19 In the Range Mode, you use the counter ranges to specify the outputs to be active within each range. Ranges may overlap. The ranges are defined using the Starting and Ending Values (M0:e.10-33). The Range Outputs fields (M0:e.3-8) contain the output patterns that specify which outputs are active. Output patterns are applied to the Output Status field (I:e.4/8-15) and output terminals when the count is within the associated range (e.g.
2-20 Module Operation When using Rate Mode, use the Ring Counter and set the Reset Value/Maximum Count Value (M0:e.34)) to 32,767. Doing so allows the counter to roll over after reaching 32,767. If the Linear Counter counts beyond 32,767, it will cause an overflow (as explained in Linear Counter Overflow/Underflow located in Chapter 5). Appendix D contains blank worksheets to assist you when configuring your module for Rate Mode operation.
Module Operation 2-21 Sequencer Mode Use this mode when a repeatable sequence of events is required. This mode allows you to program a sequence of up to 24 steps. Configuration To define a step, you: • set a bit in the Valid Steps field which corresponds to the step • program the Step Preset value • program the Step Output value IMPORTANT Appendix E contains blank worksheets to assist you when configuring your module for Sequencer Mode operation. The Valid Steps (M0:e.2 to M0:e.
2-22 Module Operation The Initial Output (M0:e.3/8-15) is applied to the Physical and Soft Outputs only when the sequencer is initialized. Initialization occurs when the Function Control bit (M0:e.1/12) is toggled from 0 to 1, or when a pulse counter reset occurs and the Sequencer Reset bit (M0:e.1/0) is set to 1. IMPORTANT Although the Valid Steps can be dynamically changed by adding or removing steps while the Function Control bit (M0:e.
Module Operation 2-23 Sequencer Mode Operation A step is reached on the next count after the Accumulated Count matches the Step Preset value. When a step is reached, the Step Output value for that step is applied to the Physical and Soft Outputs. When the sequencer is first enabled (or reset), the Initial Output pattern (M0:e.3/8-15) is applied to the Physical and Soft Outputs. The module then proceeds through each step in the sequence in ascending order (1-24), as defined in the Valid Steps field (M0:e.

Permanent damage may result if some are ON and some are OFF. Operating in the 10-30V dc range with the switches set for the 4.5-10V dc range will damage the module.
3-4 Installation and Wiring JW1 Settings Select 300 µs or 10 ms filtering to debounce the limit switch input. Position the jumper as follows: 321 321 JW1 JW1 10 ms Filter 300 us Filter The LS input allows you to make a direct connection to nominal voltage levels of 5, 12, or 24V dc. The ON voltage ranges are as follows: Wiring terminal Limit Switch ON range LS (24V dc) 16.5-30V dc LS (12V dc) 9.4- 10.5V dc LS (5V dc) 3.8-5.
Installation and Wiring Installing the Module 3-5 Installation procedures for this module are the same as any other discrete I/O or specialty module. IMPORTANT ATTENTION Set the dip switches before installing the module. Disconnect power before attempting to install, remove, or wire the module. Make sure your SLC power supply has adequate reserve current capacity. The module requires 320 mA at 5 volts. 1. Align the full sized circuit board with the rack card guide.
3-6 Installation and Wiring Important Wiring Considerations Use the following guidelines when planning the system wiring for the module: • Install the SLC 500 system in a NEMA rated enclosure. • Disconnect power to the SLC processor and the module before wiring. • Make sure the SLC 500 system is properly grounded. • Group this module and low voltage DC modules away from AC I/O or high voltage DC modules. • Shielded cable is required for high speed input signals A, B, and Z.
Installation and Wiring Input and Output Connections 3-7 Input and output wiring terminals are located on the front of the module, behind the terminal cover. When you connect input and output devices, you will also be concerned with the settings of dip switch SW1 (input connections), dip switch SW2 (output connections), and jumper JW1 (limit switch input connections). Refer to Dip Switch and Jumper Locations beginning on page 3-2 for the location and description of SW1, SW2, and JW1.
3-8 Installation and Wiring Outputs The module provides four Physical Outputs. They can be controlled by the module when certain counter conditions are met, or they can be controlled from the user program (refer to M0:e.0 in Chapter 4). The outputs are bipolar transistors connected in a sinking (open collector sinking) configuration. When the output is energized, it sinks the current. You can select an output voltage range of 4.5-10V dc or 10-30V dc.
Installation and Wiring Removing the Terminal Block 3-9 The removable terminal wiring block eliminates the need to rewire a module if it is removed from the rack. Each terminal will accept two #14 AWG wires. ATTENTION Disconnect power before attempting to install, remove, or wire the removable terminal wiring block. To avoid cracking the removable terminal block, alternate the removal of the slotted terminal block release screws.
3-10 Installation and Wiring Wiring the Removable Terminal Block The terminal screws can be turned with flat or cross slot screwdrivers. Each screw should be turned tight enough to immobilize the wire’s end. Over tightening can strip the terminal screw. The torque applied to each screw should not exceed 5.3 inch pounds. A wiring template for the terminal block is provided below.
Installation and Wiring Differential Encoder Wiring 3-11 Refer to your encoder manual for the proper cable type and length. Due to the topology of the module’s input circuits, terminating the shield at the encoder end provides the highest immunity to EMI interference. Connect EARTH ground directly to the encoder connector housing.
3-12 Installation and Wiring Single-Ended Encoder Wiring (Open Collector) Refer to your encoder manual for the proper cable type and length. Due to the topology of the module’s input circuits, terminating the shield at the encoder end provides the highest immunity to EMI interference. Connect EARTH ground directly to the encoder connector housing.
Installation and Wiring Single-Ended Encoder Wiring (Sourcing) 3-13 Refer to your encoder manual for the proper cable type and length. (The Allen-Bradley 845H sourcing encoder is not compatible with this module.) Due to the topology of the module’s input circuits, terminating the shield at the encoder end provides the highest immunity to EMI interference. Connect EARTH ground directly to the encoder connector housing.

Configuration and Programming 4-11 M0:e.3 through M0:e.8 - Range 1 through 12 Outputs (Dynamic) Use these words to program specific on/off output patterns. The Range 1 through Range 12 Outputs, shown below, are associated with Ranges 1 through 12 respectively. Each output field consists of 8 bits. The four lowest numbered bits correspond to the module’s Physical Outputs. The four highest numbered bits correspond to the Soft Outputs.
4-12 Configuration and Programming M0:e.9 Bits 0 through 7 This value represents the interval (Rate Period) of which the Rate Calculation will be performed. The integer value entered in bits 0-7 can range from 1-255. It is multiplied by 10ms to obtain the actual Rate Period time. If reset to 0, a fault will occur. Refer to Selecting the Rate Period Parameter in Chapter 2. M0:e.9 Bits 8 through 15 Bits 8 through 15 are reserved and must be reset to 0. M0:e.10 through M0:e.
Configuration and Programming 4-13 The Range Starting Value specifies the start of the range and the Range Ending Value specifies the end. While using the Ring Counter Type and the Starting > Ending, the range extends across the rollover count (Maximum Count Value). While using the Linear Counter Type and the Starting > Ending, the range extends from Starting to 32767 and from -32767 to Ending. Refer to the Range Mode with Linear Counter example in Chapter 2. Ranges may overlap.
4-14 Configuration and Programming Reset Value When the module is configured for a linear counter, the counter is reset to the value you enter in this word. This word allows you to initialize the counter, when a reset condition occurs, to a specific value other than zero. The range of this value is -32767 to +32767. The example below illustrates reset values of -32,767 and +32,767.
Configuration and Programming 4-15 O:e.0 Bits 0 through 7 - Direct Outputs These bits are used for direct user program control of the outputs.

Appendix B M0 and M1 Files This appendix contains important information you should know when applying M0 and M1 files. This information supplements specific information contained in earlier chapters of this manual. M0 and M1 files are data files that reside in specialty I/O modules only. The High-Speed Counter module only uses M0 files. There is no image for these files in the processor memory. The application of these files depends on the function of the particular specialty I/O module.
B-2 M0 and M1 Files Restrictions on Using M0-M1 Data File Addresses Monitoring Bit Addresses M0 and M1 data file addresses can be used in all instructions except the OSR instruction and the instruction parameters noted below. Instruction Parameter (uses file indicator #) BSL, BSR File (bit array) SQO, SQC, SQL File (sequencer file) LFL, LFU LIFO (stack) FFL, FFU FIFO (stack) For SLC 5/02 processors, the M0/M1 Monitoring option is always disabled.
M0 and M1 Files B-3 If you need to show the state of the M0 or M1 addressed bit, you can transfer the state to an internal processor bit. This is illustrated below, where an internal processor bit is used to indicate the true/false state of a rung. B3 ] [ EQU B3 ] [ 0 1 EQUAL Source A N7:12 Source B N7:3 M0:3.0 ( ) 1 This rung will not show its true rung state because the EQU instruction is always shown as true and the M0 instruction is always shown as false.
B-4 M0 and M1 Files Transferring Data Between Processor Files and M0 or M1 Files As pointed out earlier, the processor does not contain an image of the M0 or M1 file. As a result, you must edit and monitor M0 and M1 file data via instructions in your ladder program. For example, you can copy a block of data from a processor data file to an M0 or M1 data file or vice versa using the COP instruction in your ladder program.
M0 and M1 Files B-5 The following table shows the expected maximum access times per instruction or word of data for the SLC 5/02, SLC 5/03, SLC 5/04, and SLC 5/05 processors.
B-6 M0 and M1 Files If you are using a SLC 5/02 Series B processor, add 1930 µs to the program scan time for each bit instruction addressed to an M0 or M1 data file. If you are using a SLC 5/02 Series C processor, add 1157 µs. COP COPY FILE Source Dest Length #B3:0 #M0:1.0 34 If you are using a SLC 5/02 Series B processor, add 1580 µs plus 670 µs per word of data addressed to the M0 or M1 file. As shown above, 34 words are copied from #B3:0 to M0:1.0.
M0 and M1 Files Minimizing the Scan Time B-7 You can keep the processor scan time to a minimum by economizing on the use of instructions addressing the M0 or M1 files. For example, XIC instruction M0:2.1/1 is used in rungs 1 and 2 of the figure below, adding approximately 2 ms to the scan time if you are using a SLC 5/02 Series B processor. 1 M0:2.1 ] [ 1 2 B3 ] [ 12 B3 ( ) 10 M0:2.1 ] [ 1 B3 ( ) 14 XIC instructions in rungs 1 and 2 are addressed to the M0 data file.
B-8 M0 and M1 Files Capturing M0-M1 File Data The first two ladder diagrams in the last section illustrate a technique allowing you to capture and use M0 or M1 data as it exists at a particular time. In the first figure, bit M0:2.1/1 could change state between rungs 1 and 2. This could interfere with the logic applied in rung 2. The second figure avoids the problem. If rung 1 is true, bit B3/10 captures this information and places it in rung 2.
Appendix C Differential Encoder Information This appendix describes the wiring procedures for connecting a differential encoder to the module. Connecting a Differential Encoder For proper module operation, wire the encoder so that the Z input signal is high (true) at the same time the A and B input signals are low (false). If this condition is not met, inconsistent homing may occur.
C-2 Differential Encoder Information 5. Since the encoder may be mounted on either end of a motor shaft, the encoder may spin CW or CCW for a given shaft direction. As a result, the direction (phasing) of the encoder may be backwards. If this is the case, switch the Channel A wires with the Channel B wires. This changes the direction of the encoder signals. The wire at A(+) exchanges with wire at B(+). The wire at A(-) exchanges with wire at B(-).
