Hi friends

i want to use positive edge and negative edge bit in SCL in simatic manager.

Can someone tell me how to program it, i tried to find in the manual but not able to find anything related.

with a positive edge i have to increment a address. Like that there are several address and would like to program in SCL.

Please let me know.

Prash1985,

I use direct assignment.

B        := A And Not Mem;

Mem  := A;

Hi actually i was trying to count multiple alarms to see how man times it occurs in a machine.

in ladder it is simple.

not sure how i can implement the positive edge and negative edge within logic example i added

My usal way:

IF #x_event THEN
  IF NOT #x_trig_01 THEN
    // Do it once
    ...
  END_IF;
  #x_trig_01 := true;
ELSE
  #x_trig_01 := false;
END_IF;
