Hi 

Any idea how to get plc running? 

I have hardware mismatch- only PLC on the bench but more cards in the HW config.

PLC is 1214 safety plc.

i get an error 

I already have OB82 and OB86 which did not help -see error above.

I am not familiar with TIA but remember that in Step 7 there was programming error OB121.

Any idea what is programming error OB called in TIA- i cannot find it?

Any other ideas to bypass the issue as OB 121 programming error i dont think will help..

Regard

Thanks a lot for willingness to help.

My problem is rather fundamental and refers to the hardware config. 

I have just plc on my bench but my hardware config has plc + input cards which include safety inputs as well. PlC is also safety type 1214 FC.

The PLC does not run as it detects signal issue which i am not able to bypass with OBs which i added except OB121 which i cannot find.

I wonder if any other ideas you could suggest? 

In simulator everything runs fine.

Ciao hewking103,

I had the same problem. I solved it by moving the cards to the "Mudules not plugged in" section. You can enable this section by click on icon above. With this way I don't lose the cards configuration and when I have all the hardware I can take them back and place them on the BUS.
