you can use IEC timers (and any data that you need to retain after scan) in the FC

Simply declare it in In/Out section of the interface

and everytime you call FC from FB assign these to static variables of the calling block

for example

FC TEST

  input
     I_TRIGGER

  in/out
     IQ_TON : TON_TIME;

in code use IQ_TON as a instance variable of the timer
and link it to STAT or a value in global DB

  Hey first you said you can use IEC timers in the FC. But after you say call  FC from FB?

How can I use SFB4 in FC in the way it will be possible to reset that "TON" to repeat timing in next cycles again?

Please explain in STL. And when I try "TON_TIME" in in/out of FC as data type, that wasn't become accepted and detect invalid data type?? I did not know your mean... If it is possible explain more
