GFK-1057D High Speed Counter 2 Special Applications Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 59-2 Product Compatibility Requirements Product Version IC697 CPU 5.50 or later (CPU models 781, 782, 914, 924) MS-DOS Programming Software 5.0x or later Windows Programming Software 1.0 or later High Speed Counter Types The High Speed Counter can be configured as one of five types: A, B, C, D, or E. All counters have 12 inputs, four preset outputs, and optional PLC ladder interrupt capability. Type A In Type A configuration, the HSC has four identical and independently programmable unidirectional 16-bit counters, which can be configured for up or down operation. Each counter has three inputs: Preload, Count Pulse and Strobe. Type B In Type B configuration, the HSC has two identical and programmable bi-directional 32-bit counters. Each counter can be independently configured to operate in Up/Down, Pulse/Direction or A Quad B mode. Both counters have two independent Strobe inputs and Strobe registers. Each counter has a single Preload input to set the accumulator and a Disable input to suspend counting. This counter type can be configured to link strobes. In this mode, a count on the Counter 2 inputs will strobe both Counter 1 and Counter 2 Accumulator values into their respective Strobe 1 registers. This feature can be used to accurately measure a pulse rate against a reference pulse or to compare two different pulse rates. Type C In Type C configuration, the HSC has one differential bi-directional 32-bit counter with a Disable input to suspend counting. It also provides a Home cycle to initialize the accumulator to a pre-defined Home Position. A Home Switch input and a Marker input are used to indicate the Home Position to each counter input. The configured Home value specifies the accumulator value at the Home Position. Two sets of bi-directional counter inputs can be connected differentially. Each pair of inputs can be configured for Up/Down, Pulse/Direction or A Quad B mode. The Type C configuration has three Strobe registers with Strobe inputs and two Preload values with Preload inputs. Type D In Type D configuration, the HSC has four bi-directional 32-bit counters that can be configured to count in Up/Down, Pulse/Direction, A Quad B x1, A Quad B x2, or A Quad B x4 mode. Each counter has a marker input which can be used to set its accumulator value to the counter s Home Position value. When configured in A Quad B mode, the High Speed Counter detects and reports quadrature errors. Type E The Type E counter contains two identical 16-bit counters with Strobe and Preload inputs capable of counting Up/Down or A Quad B signals. Each has a Count Disable and a Strobe Disable input. The Type E counter is designed primarily as a Down counter, but can handle up counts to account for A Quad B jitter. When a counter counts down to zero, it turns on a dedicated preset output with a 5ms response. Type A, B, C, and D Operating Features Operating features of the High Speed Counter for Types A, B, C, and D are described below. Features that have selectable parameters are configured using the MS-DOS or Windows programming software configurator function that has been installed on your programming computer. For detailed information about selectable features, refer to the High Speed Counter User s Manual, GFK-1062. Count Rate Maximum count rates are 200 KHz with the high frequency filter and 30 Hz with the low-frequency filter. Selectable Input Filters The Count, Count Disable, and Preload inputs for each counter can be configured for a high frequency filter (2.5 microseconds) or a low-frequency filter (12.5 milliseconds). 3 High Speed Counter GFK-1057D Special Applications Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 59-3 Continuous or Single-Shot counting Each counter can be configured to operate in either continuous or single-shot mode. Continuous Counter Mode: If either the upper or lower count limit is exceeded the counter wraps around to the other limit and continues. Single-shot Counter Mode: The counter counts to either the upper or lower limit and stops. When the counter is at the limit, counts in the opposite direction back it off from the limit. Counter Accumulator The Accumulator contains the current count value of each counter. The CPU can read the accumulator value or set it from the application program. Counts per Timebase Register Each counter stores the number of counts that have occurred in a specified period of time. A timebase value from 1 ms to 65535 ms can be configured. Strobe Register Type A, B and C counters have one or more Strobe registers that capture the current Accumulator value when a Strobe input transitions. The Strobe inputs are edge-triggered and can be configured for positive-edge or negative-edge response. The Strobe registers can be configured to update at any Strobe trigger or only on the first strobe trigger Preloads Counters A, B and C have one or more Preload inputs. The Preload inputs set the accumulator to a configured Preload value. %Q bits sent from the PLC can also be used to generate Preload and set the accumulator to the configured Preload value. Selectable On/Off Output Presets Counter output signals can be configured to be On or Off when the count Accumulator reaches configured On and Off Preset values. There are four On/Off Preset outputs which can be independently assigned to any counter. An assigned output s state indicates when the counter Accumulator is between the defined On and Off points. Output polarity can be configured to On only between points or Off only between points by the relative location of the On/Off Presets. Selectable Preset Interrupts Each Preset output can generate PLC interrupts from On and/or Off transitions. Interrupts can be enabled for either or both transitions of each Preset output. Oscillator The module provides an external oscillator output that can be wired as a count input to any counter and used as a timing reference for measurement. The 5V square wave oscillator output can be configured to operate at frequencies from 15 Hz to 1 MHz. This output has a CMOS buffer with a 47 ohm output impedance. Data Commands The PLC can send data commands to the HSC through %AQ data or with a COMMREQ. These commands allow the user to dynamically modify counter operation and configuration parameters. Configuration parameters that can be dynamically modified include: accumulator value, counter limits, Preload values, On and Off Preset values and Home Position. Velocity Command A %AQ or COMMREQ Data Command can be used to generate an internal velocity of up to 100,000 counts per second. The counter accumulator will increment or decrement at the commanded velocity. Counts generated by the user count inputs will be accumulated in addition to the Velocity Command counts. Accumulator Adjust A data command can be used to adjust the accumulator value from 128 to +127 counts at any time. GFK-1057D High Speed Counter 4 Special Applications Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 59-4 Type E Operating Features Operating features of the High Speed Counter for Type E are described below. Count Rate and Input Filters The maximum count rate with the low-frequency filter (12.5 milliseconds) is 30 Hz; with the high-frequency filter (2.5ms), the maximums are 200 KHz in Up/Down mode and 800 kHz in A Quad B mode. The Count, Count Disable, and Preload inputs for each counter can use either filter, but the Strobe and Strobe Disable inputs use only the high-frequency filter. Continuous or Single-Shot Counting Each counter can be configured to operate in either continuous or single-shot mode. Continuous Counter Mode: When the counter decrements to zero, it turns on the fast response output and automatically preloads itself to the preload value and continues counting. Single-shot Counter Mode: When the counter counts to zero, it turns on the fast response output and ignores count pulses until a preload occurs. Preloads A rising edge on the Preload input, a rising edge on the %Q Preload Accumulator bit, or the counter decrementing to zero in Continuous mode will set the accumulator to a configured Preload value. Preloads caused by the Preload input and count decrementing to zero will set a %I bit in the PLC to indicate a preload occurred. Strobe Register Stack Each counter has a Strobe Register stack which will store up to four strobe values. Strobes can be configured to occur on rising, falling, or both edges of the Strobe input. %I bits indicate how many strobes have occurred. A Reset Strobes %Q bit or a Preload clears the Strobe Register stack and %I indicators. A Strobe Disable input causes all Strobe input transitions to be ignored. Counter Outputs The Type E counter supports two types of output presets, Fast Response and Standard. Fast Response: There is one dedicated fast response output for each accumulator. The fast response output turns on within 15ms of the associated counter decrementing to zero, with less than 2ms variation. In addition, two output modes are supported for the fast response outputs. Pulse Output Mode: The output turns on when the Accumulator counts down to zero and stays on for a configured duration, from 1 to 1000 milliseconds. Latched Output Mode: (Single Shot mode only) The output turns on when the Accumulator counts down to zero and stays on until a Preload occurs. Standard Output Presets: Outputs 3 and 4 can be assigned to either counter and configured to be On or Off when the count Accumulator reaches configured On and Off values. An assigned output s state indicates when the counter Accumulator is between the defined On and Off points. Output Interrupts Interrupts can be enabled or disabled for Off to On transitions of the fast response outputs. Interrupts can be enabled or disabled for either transition of the standard preset outputs. Oscillator The module provides an external oscillator output that can be wired as a count input to any counter and used as a timing reference for measurement. The 5V square wave oscillator output can be configured to operate at frequencies from 15 Hz to 1 MHz. This output has a CMOS buffer with a 47 ohm output impedance. Data Commands The PLC can send data commands to the HSC through %AQ data or with a COMMREQ. These commands allow the user to dynamically modify counter operation and configuration parameters. Configuration parameters that can be dynamically modified include: Preload values, On and Off Preset values, and Fast
