I have one step 7 simatic program in which I noticed that one bit is constantly changing every two sec, but I cannot find any timers in the program.
How is that made? Can you give me some guidelines?
Thanks
Thank you L D[AR2,P#0.0], I have set this byte MB 0.
Now I can see that all bits M0.0 to M0.7 blinking at different frquency.
I'm pretty much sure about M0.7. It is blinking in such way that 1 is present for 1 sec and pause is also 1 sec,so overall period is 2 sec.
How to determine the rate blinking of other (faster) bits?
