I am new to the Unity Pro software/Modicon M340 processor (previous experience with AB). Does this processor have an instruction for a retentive timer? All I can find is a TON instruction, which resets when the input is removed. I would like a timer that holds its time unless specifically reset (an RTO timer in the AB world).
Any help would be greatly appreciated.

Full Version: Does Modicon M340 have a Retentive Timer Block?
No, you have to create by yourself.
Yes something like this..
Take care to erase the elapsed times to zero. when reinitialised.
the Mirror_S6 bit is a copy of %S6 at the very end of the program to create a rising edge on %S6 which is the system bit for 1 sec.

Hi Tony
Have a look at the PL7_3_TIMER in the obsulete function blocks library
This has an enable and a control input, while the control input is on the timer functions,
turning off the control input pauses the system retaining the time passed
Hope this helps
