4.6.3 Pulse Catch Module cont.
— 4-240 —
2. Functions
1) Pulse Catch Function
The Pulse Catch and Counter Module can hold an input ON signal that is shorter than the
CPU Module scan time until the CPU Module is ready to read the signal. The input state is
stored in an input relay in the CPU Module.
a) Number of inputs: 16
b) Minimum ON signal width
1 ms (with 8 Count Mode channels)
2 ms (with 16 Count Mode channels)
2) Counter Function
The Pulse Catch and Counter Module is able to count the number of input ON signal
pulses. It can also store the count and a carry in input registers in the CPU Module.
a) Number of input channels: 16 channels max., switch between 8 and 16 channels.
b) Maximum input signal frequency:
500 Hz (with 8 Count Mode channels)
250 Hz (with 16 Count Mode channels)
c) Count Modes:
Absolute: Counts from 0 to FFFF(h) and outputs a carry above FFFF(h).
Incremental: Counts the number of input pulses in a CPU Module scan.
1) The pulse catch and counter functions can be used simultaneously if both are set to
“Used.”
2) The pulse catch and counter functions can be used for the same external input circuit.
