Hello Ashako,

The timers set time, elapsed time remaining time will only be shown in STEP in SFC and SFC type.

You can see the attached file for your reference.

Hope it helps you!

 

Tnx, But is there any way to use this timer for transition?
as you may know we can use the step timer in transition in S7-Graph, just want to know is there any way to do the same at SFC?

Split from SFC type - using internal timers.

 Hello,

No! SFC Transition doesn't have any timer settings or Timer to pass on to next state.

A transition contains the conditions under which a sequential control system passes control from one step to the next. Several conditions can be logically combined using Boolean operators. The result of the logic operation determines whether the next step is enabled.Transitionsare theoretically configured in the same way as steps.

Hi,

In a SFC type, you can create a timer under Characteristics -> Timers and use it in the step to activate and to set them mode + timer value. The timer characteristic is based on block: TIMER_P.

You can use the timer to evaluate the transition, you can see it count down if you use the PTIME value. See attachment.
