Example: Maintaining Catch Input
When a catch input is received, the catch input relay assigned to a catch input is turned on for only one scan.
This example demonstrates a program to maintain a catch input status for more than one scan.
Input I2 is designated as a catch input using the
Function Area Settings.
When input I2 is turned on, special internal relay
M8091 is turned on, and M0000 is maintained in
the self-holding circuit.
When NC input M1 is turned off, the self-holding
circuit is unlatched, and M0 is turned off.
M0 is used as an input condition for the
subsequent program instructions.
