Hi,

I have big problem with IM 151-1 Standard. (6ES7 151-1AA05-0AB0)

I have already 1 year this moduls, and never problem. I have alse yet 3 same complet moduls which work perfect.

When I was first time this problem, I replaced with new IM 151. This worked 3 hours and same problem. And I was again replaced with new IM 151. After last changed with new modul I had immediately same problem.
