Chapter 1 About the Modules What This Chapter Contains Read this chapter to learn about types, features, and capabilities of the encoder/counter modules. Module Description and Features The modules install into the POINT I/O terminal base (1734-TB or 1734-TBS) and interface with the Point I/O DeviceNet Pass-through (1734-PDN) or the Point I/O DeviceNet Adapter (1734-ADN).
1-2 About the Modules The outputs are rated to source 0.5A at 10 to 28.8V dc. The output may be tied to an input. This lets you cascade counters of multiple 1734-VHSC modules. The counter has 4 user-selectable On-Off values (windows) associated with it. Tie either output to any or all of the window signals. Operating Modes The modules operate in the modes shown in the table. Mode Description Counter Mode Read read incoming single-phase pulses, return a binary count.
About the Modules 1-3 Channel A input is used as the counting pulse while channel B is used to determine the direction. [B = High, Count = Down; B = Low or floating (not connected), Count = Up] The Channel B input may be tied high or low for unidirectional counting, or toggled for bidirectional counting.
1-4 About the Modules Absolute encoders typically have higher speed requirements (200 KHz typical) for motion control applications. An absolute encoder has a unique code associated with each position, so the exact position is always known, even if the system power is turned off.
About the Modules 1-5 X4 Multiplying Encoder Mode Quadrature input signals are used to count on leading and trailing edges of A and B for a bidirectional count, and channel B is used to determine the direction. [ B = leads A, Count = Down; B = follows A, Count = Up ] Period/Rate Mode The Period/Rate mode returns an incoming frequency and a total accumulated count to the POINTBus, by gating an internal 5 MHz internal clock with an external signal.
1-6 About the Modules As the frequency of the incoming pulse train at the Z (Gate/Reset) terminal increases, the number of sampled pulses from the 5MHz clock decreases. Since accuracy is related to the number of pulses received over the sample period, the accuracy decreases with increasing frequencies at the Gate/Reset terminal. Refer to the following Scaling table.
About the Modules 1-7 Continuous/Rate Mode The Continuous/Rate Mode returns an incoming frequency and a total accumulated count to POINTBus, by gating an internal 5 MHz internal clock with an external signal. Similar to the Period/Rate mode except outputs in this mode are updated continuously. This mode determines the frequency and total number of input pulses by counting the number of internal 5 MHz clock pulses over a user-specified number of input signal pulses.
1-8 About the Modules Rate Measurement Mode The Rate Measurement mode determines the frequency and total number of input pulses over a user-specified sample period. At the end of the interval, the module returns a value representing the sampled number of pulses and a value indicating the incoming frequency. When you update the count and frequency, you check any associated outputs against their associated presets.
About the Modules 1-9 New Data Indicator A two-bit counter, C1 and C0, is updated every time an event occurs, indicating that new data is available in the Stored/Accumulated Count words.
1-10 About the Modules Operating Mode Features See the table for a summary of features active in each mode.
About the Modules 1-11 Store Count Mode 2: Store/Wait/Resume In mode 2, the rising edge of a pulse input on the Z Gate/Reset terminal reads and stores the current counter value in the Stored/Accumulated Count word and inhibit counting while the Z Gate/Reset terminal is high. Counting resumes on the falling edge of the pulse at the Z Gate/Reset terminal. The stored count information remains until it is overwritten with new data.
1-12 About the Modules Store-Reset/Start Start Counting Store Count, and Reset to zero Continue Counting Output Control To connect an output to a compare window, you could program the module accordingly: • Tie Output 0 to Window 0 • Program Window 0 ON Value to 2000 • Program Window 0 OFF Value to 5000 ON-OFF Operation of Output 0 Output remains energized for 3000 additional counts Output turns ON at count value of 2000 Output turns OFF at count value of 5000 If the OFF value is greater than the ON
Chapter 2 Install the Module What This Chapter Contains Read this chapter for information about how to install the modules. The 1734-VHSC module is a two-module set. Module 1 houses the 1734-VHSC functionality while module 2 provides screw terminals necessary to access chassis ground (Chas Gnd) and common (C). Module 2 also connects terminal 4 to 5 and terminal 6 to 7 for ease of wiring power to the input device. Module 2 is not necessary for VHSC functionality but eases customer wiring.
2-2 Install the Module ATTENTION Environment and Enclosure This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
Install the Module The wiring base assembly (1734-TB or 1734-TBS) consists of a mounting base (cat. no. 1734-MB) and a removable terminal block (cat. no. 1734-RTB or 1734-RTBS). You can install the assembly, or just the mounting base. To install the mounting base and wiring base assembly on the DIN rail, proceed as follows. ATTENTION POINT I/O is grounded through the DIN rail to chassis ground. Use zinc-plated, yellow-chromated steel DIN rail to assure proper grounding.

Very High-Speed Counter Module Input and Output Data 3-3 Finally, in rate measurement [7] configuration, it is the total number of pulses seen at the A input accumulated over each period as specified by the product of the time base x gate interval. The range of values occupy the entire 32-bit size from 0 ≤value ≤0xFFFFFFFF (4,294,967,295). Changing the configuration does not clear these words.
3-4 Very High-Speed Counter Module Input and Output Data EEPROM Fault status bit (EF) - If a fault is detected with the EEPROM during power up tests, this bit is asserted to 1. It indicates that the content of the EEPROM has been corrupted, most likely caused by loss of power during an executing write. Not Ready status bit (NR) - Whenever power is applied to the module, the hardware must be initialized. During this time, the NR bit is asserted and the green module status indicator flashes.
Very High-Speed Counter Module Input and Output Data Output Data 3-5 Counter Control (Word 1) VR Value Reset of stored/accumulated count. The transition of this bit from 0 to 1 clears the stored/accumulated count word. CP Counter Preset. The transition of this bit from 0 to 1 sets the counter to the value specified by the Preset words. Outputs are adjusted according to the window compare values. CR Counter Reset. The transition of this bit from 0 to 1 clears the counter.
3-6 Very High-Speed Counter Module Input and Output Data Pulse Width Modulation (PWM) Value (Output Word 3) When the module is programmed for a PWM [3] configuration, the time base is enabled, the counter rollover, which is defined as the 1st ON and 1st OFF value for the respective channel is used. Ties can be used to direct the PWM signal to any or both outputs. The range of PWM values is 0 ≤value ≤9500 decimal (0.00% ≤value ≤95.00%).
Very High-Speed Counter Module Input and Output Data 3-7 Filter Selection (Configuration Word 2) This byte sets the A/B/Z input filters. Filter Selection 07 06 05 04 0 ZF BF AF 03 02 01 00 FS 0 0 0 0 No Filter 0 0 0 1 50 kHz (10 µs + 0 µs/-1.6 µs) 0 0 1 0 5 kHz (100 µs + 0 µs/-13.2 µs) 0 1 0 0 500 Hz (1.0 ms + 0 µs/-125 µs) 1 0 0 0 50 Hz (10 ms + 0 ms/-1.
3-8 Very High-Speed Counter Module Input and Output Data In the counter modes (counter [0], x1 encoder [1], x2 encoder [2], pwm [3], x4 encoder [4]), it attenuates the counter display, for example, 20 divides count+1 by 20. The value may be in the range 0 < value ≤255. The result of requesting a number other than 1 performs the function: (COUNT + 1) / ATTENUATION. This is useful for scaling a large counter value to a smaller 16-bit value or a percentage.
Very High-Speed Counter Module Input and Output Data 3-9 Scalar (Configuration Word 7) This byte scales the Z signal in the period/rate [5] and continuous/rate [6] configurations. If the filter is applied, then the filtered Z is scaled. Only one bit of the scalar should be set. Selecting a scalar causes accumulated counts to be adjusted accordingly. Selecting a scalar of 128 increases the accumulated count by 128 after 128 Z pulses are received.
3-10 Very High-Speed Counter Module Input and Output Data Rollover (Configuration Word 10) This long word sets the number of counts the counter accumulates before rolling over. For example, a value of 1000 produces a count sequence of: 998, 999, 0, 1, 2… while incrementing or 2, 1, 0, 999, 998… while decrementing. Rollover is a 32-bit number with a useable range of 1 ≤value ≤0x01000000 (16,777,216).
Very High-Speed Counter Module Input and Output Data 3-11 Safe State Values (Configuration Words 20 through 22) When either the host transitions to PROGRAM mode or a communication fault (broken network cable) occurs, the module copies these safe state words (counter control, output control, and PWM value) into its real-time working buffer.
