Hi all,
This is my situation:
I converted an S5 program to S7.
Which converted without problems except for CPU to CPU communication which is not necessary anymore. Now in the S5 program it uses indirect addressing of DB's which causes confusion and that some part switch between DB's all the time.
But the main problem/confusing situation is this:
I make a marker true in one location say m44.4.
Here it remains solid.
Then in another part of the program I have an Issue that DB, AR1 and STATUS… (STL monitoring) change all the time. But shouldn't effect my status.
In this part I use the same marker m44.4, but here it switches between on and off in the same rate as the STL monitoring statuses.
Now nothing else in the program is affecting m44.4 not by mw nor mb or anything else.
If I change m44.4 into a different range it still changes.
I was wondering if anyone could help me with this situation or at least explain me how a M bit can change at 1 place while it remains true at another place because I am not getting it.
