Hi all,
some time ago Siemens had problems with their OP25 panels. After some time black lines would appear on the screen. The number of black lines would increase over the time until the screen would be totally unreadable. Siemens officially acknowledged the problems and arranged a replacement for all the "bad" panels. The reason for the whole thing was blamed on a bad production run at a subsupplier.
But now I am experiencing the SAME PROBLEM on several OP27 panels !
Does this mean that it is starting over again ?
And it is not helpful either that production of both OP25 and OP27 has stopped. To use the replacement OP270 requires quite a few modifications being made to the user program. I am foreseeing a nightmare.
My question:
Do others out there experience problems with the OP27 ?
