8.8 Timer “tFct”
tFct: Timer function
Time-dependent control actions can be carried out with the help of the timer. The
timer signal (timer 1+ 2) shows whether the timer is active. It can be output via the
binary outputs or processed internally.
The timers are started or canceled via the binary functions.
v Chapter 8.6 “Binary functions “binF””
The current timer run times can be viewed at the operator level (process data).
