 Please how did you resolve this error...??

Hi 

the best way is check the actual module configuration. the PLC always in rack 0 / 1, then just check the slot of plc back plane.

Hi,

You can physically look at the rack and tell which slot the cpu is in.

The first slot is no 1.

This is normally where the power supply is. It can be one or two slots wide depending on the type of power supply.

Normally the cpu comes next, so this will be slot 2 or 3, but the cpu can also be in other slots.

I hope this helps.
