Working hours Counter Siemens STEP7

[niek.t]

Hi Guys,

Just a quick question (out of interest)

Is there in Step7 (not TIA) a function for work hour counting?

I had implement those in the past and always ended up making them myself...

I've always just counted seconds into a UDINT. Call a run-time routine by interrupt once/second. The rungs are very simple: Condition -> Seconds = Seconds + 1. It's good for well over 100 years of continuous running.

I think that counts as a "no."

Good Luck,

Yosi

There is a runtime meter function built in to the PLC. Note that it counts hours only.
