Hi,
The problem I try to solve is, I have a machine with different pumps in, I need to register how many hours each pump has been running to keep track of service.
I tried the using Wago's Blink (from util.lib) to generate pulses of 1 sec (500 ms low 500 ms high) and then CTU's for counting sec, min and hours.
Of cause I can just make two counters one counting up to 3600 sec and then hours.
But is there a nicer way to do this, and at the same time make the counted time "RETAIN and PERSISTANT"?
By use of the date and time function in the OSCAT lib?
Hi, "ACTUATOR_PUMP" does not solve your problem? It has an output for "operating hours". Also "BURNER" has such a counter. Or "F_LAMP"? To be honest, I did not test those functions until now, but they should do the job.
To get the counter results surviving a RESET can be a difficult job.
Best regards
Rainer
And, of course more elegant for an application where you only want to have a runtime counter: The function ONTIME in OSCAT 333
