Hello, as first - download all the OB8x, OB121 and OB122, the CPU should at least start to RUN mode. Check the conditions for these expansion racks, like the terminator at the last receiver (6ES7461-0AA00-7AA0) and used cabling (6ES7468-1...). And as addition, there is the manual for S7-400 PLC modules. Regards Sydney |

The rotary switch is on the IM in expansion unit. After changing , probably you need a power up of the PLC. Switch off and Switch on the power supply |
