I have a project consisting of an S7 416 CPU with distributed IO. The customer requires the CPU to remain in the run mode even if one of the remote racks is powered down. I compile and download the program but the only way to keep the CPU in run mode is by deleting the fault OB's (85,86 & 122) and reinserting new OB's and the downloading them to the PLC. Is it possible to alter the settings on complie to eliminate the need of deleting the OB's.

Thanks in advance
