Hi,
This is in relation to my previous post (title: PLC trouble?).
I was thinking maybe something is wrong with the cpu or the modular-type PLC backboard because when limit switch A is activated, on the program it is limit switch B that reacted. I have confirmed that program has no error, as sequence is running correctly. Trouble arises due to the "unexplainable" limit switch issue.
But this problem does not happen always, but it happens on the same location persistently. Limit switch has been confirmed good as per manual testing.
What do gurus think about this?
