Hello kormotech;

Actually, William_B proposed another solution,  the Runtime Meter ( RTM) instruction for the S7-1200, in an earlier discussion.

See this link:

This instruction returns the nber of hours of operation of a motor controlled by your CPU. Study the online help of your programming software. 

Hope this helps, 

Daniel Chartier

NR- number of my timer

MODE- (i have choose 1 and 6) 

PV- setpoint  timer

RET_VAL- error massege

CQ- timer status

CV-  current value

Hi

Your Counter Idea should be possible. You could make a clock ie. 1 Minute, detect the positive edge, AND your motor Running. The use the INC function simply adding 1 to a Dint.
