Hello all

We have a Siemens OP7 connected to S7-300 via Profibus.

When we power up the system after a lengthy shutdown the OP7 screen becomes inverted ie. characters in reverse. We have to reboot numerous times as the screen then shows up full of character blocks.

Is the OP7 failing or is something in need of alteration on the OP?

Any info will be greatly appreciated.
Thanks in advance.
