I have a strange problem in my software. I'm using a 315-2DP PLC and picked (what I thought) a free timer to use in my code. Timer 128.
I used T128 as an extended pulse timer but the strange thing is that it keeps triggering for around 200ms ?
So, it comes on then 200ms (ish) later it goes off. I've check the reference data and it doesn't appear to be used in the software. The software is quite basic LAD and I can't see any STL so I don't think it's being brought on by a cross-area pointer or anything like that.
I just wondered if this timer might have gone 'rogue' and be giving spurious signals??
Anyone seen anything like this before or, does anyone know how else I can check to see if the timer is being used??
