The Genius I/O High-speed Counter block is a self-contained, configurable I/O module which provides direct processing of rapid pulse signals up to 200kHz. Typical applications include: Turbine flowmeter Meter proving Velocity measurement Material handling Motion control Process control The block may be powered by 115VAC and/or 10 to 30VDC. If the main power supply to the block is 115 VAC, a 10 VDC-30 VDC power source can be used as a backup. Both 115 VAC and DC power may be supplied simultaneously; if the 115 VAC source fails, the block will continue to operate on the DC backup power. Any DC source that can provide an output in the range of 10 VDC to 30 VDC can be used. The source must meet the specifications listed in this chapter. With both AC and DC power applied, block power will be taken from the AC input as long as the DC voltage is less than 20 volts. The block provides 1, 2, or 4 counters of various complexity. If block has its own communications capability and microprocessor. It can count and provide outputs without the need to communicate with a CPU. The block has four control outputs. It also provides a +5 volt DC output, and a square wave oscillator output that can be used as a timing reference. The block s two topmost LEDs indicate the status of the block and the status of communications with the CPU. Four smaller LEDs indicate the on/off status of each output. 1-2 Genius I/O High Speed Counter - May 1994 GFK-0415 High-Speed Counter Block Specifications GENERAL Dimensions 8.83 h. X 3.56 w.

For the Series Six PLC, Bus Controller version IC660CBB902G or IC660CBB903G or later is required for blocks assigned to I/O references, to assure data coherence. For blocks assigned to register memory, earlier versions of IC660CBB902 and 903 can be used. Bus Controllers CBB900 and 901 cannot be used with a High-speed Counter. A Hand held Monitor version 3.5 (IC660HHM501D) or later is required to perform configuration and block monitoring functions. To use all features of High speed Counter block version 120D or later, HHM version 4.0 (HHM501G) or later is required. For earlier HHM versions, an upgrade kit (44A286347 G05) can be ordered. Block Operation The High-speed Counter accepts twelve input signals, and can provide four output signals, plus an oscillator output and a +5 volt DC output. a42997 OSCILLATOR OUTPUT 1 + 5 VOLTS INPUT 1 INPUT 2 INPUT 3 INPUT 4 INPUT 5 INPUT 6 INPUT 7 INPUT 8 INPUT 9 INPUT 10 INPUT 11 INPUT 12 OUTPUT 2 OUTPUT 3 OUTPUT 4 The block can have 4 counters, 2 counters, or 1 counter. Selection is made when the block is configured. Type A configuration has 4 identical, independent counters Type B configuration has 2 identical, independent more complex counters Type C configuration has 1 complex counter. 1 1-4 Genius I/O High Speed Counter - May 1994 GFK-0415 OSC +5V INPUTS COUNTER 3 COUNTER 1 a42999 OUTPUTS COUNTER 2 COUNTER 4 TYPE A COUNTER 1 a42998 OUTPUTS COUNTER 2 TYPE B OSC +5V INPUTS COUNTER a42996 OSC OUTPUTS +5V INPUTS TYPE C Block Inputs The block accepts up to four differential counter inputs, and up to eight control inputs. Counter Inputs The four differential counter inputs (I1+ through I4 ) correspond to terminals 16 through 23 on the block. Depending on the block s configured type, these inputs may be used for: Pulse signals Direction signals A quad B signals The counter inputs can be assigned to either TTL or non-TTL voltage levels independently of the control inputs. Control Inputs The eight control inputs, designated C1 through C8 , correspond to block terminals 26 through 33 and terminal 35. Only C8 is differential; C1-C7 are single-ended. Depending on the block s configured type, these inputs can be used for: Preload Inputs Strobe Inputs Disable Input Home input Marker input Control inputs can also be assigned to use either TTL or non-TTL level signals. 1 GFK-0415 Chapter 1 Introduction 1-5 Block Outputs The block provides four counter outputs, plus an oscillator output, and a +5 volt output. Counter Outputs The block s four counter outputs can be used to drive indicating lights, solenoids, relays, and other devices. Short circuits and surges of short duration are tolerated. Each output circuit provides built-in protection against power surges caused by wiring errors. The commanded state of each output is shown by an individual LED on the block. Output Presets The block s outputs can be programmed to turn on or off when the accumulated count reaches appropriate values. Each counter output has two Preset points, ON and OFF. The output state indicates when the counter Accumulator value lies between the defined points. For example: |
