HA Retentive timer LIBRARY required
I required HA Retentive timer (RTON) for my application.
Or otherwise i need HA_CS31_CTU with retentive option. If I defined HA_CS31_CTU as RETAIN then it is not syschronizes the counter data with redundant plc.
timer should not reset after power failure or enable input is low as well as it should synchronize data with redundant plc.
so please help me in this regard.
As I know, CTU could not be retain at power supply failure. You have to create own logic for that, using transfer of CTU's output to retain variable.
There are different techniques for that, you could see other issue in the forum:
