1-4 Product Overview
The HSCE module provides a total of six counters and eight outputs,
divided into two channels. Each channel contains the following:
One 24-bit counter: this counter has two pulse inputs, A and B; its
primary purpose is to count pulses from an incremental pulse encoder.
Two 16-bit counters: each counter has a single input, C or D, in each
channel; its primary purpose is simple pulse counting, up or down.
Four discrete outputs: each output is capable of sourcing 24 V to a load,
at 200 mA continuous or 500 mA peak output current. The outputs
require external, user-supplied 24 VDC power.
The HSCE module operates asynchronously from the PLC. It accumulates
pulse inputs and controls outputs according to presets or other conditions
you programmed into the module by Relay Ladder Logic (RLL) program.
Each 24-bit counter has three control inputs:
INDEX latches the count value, or reloads the counter preset value.
Index can also be configured for a Reset-and-Go operation, which clears
the count value before counting continues.
INHIBIT holds the count value.
RESET sets the count value to zero.
The 24-bit counters provide the following counting modes:
Quadrature counting (1X, 2X, or 4X resolution).
Non-quadrature up/down counting, or direction counting.
The 16-bit counters provide the following counting modes:
Retriggerable one-shot mode.
Divide-by-N counting mode.
Square-wave generator mode.
Triggered strobe mode.
Binary, Up/Down, Recycle mode.
Cascaded counting.
