CPU315-2 =>Profibus =>IM178
Thanks Guys,
I've chechked the connections and cable.
They are all the same and still it doesn't work.
Ive got just one module connected to the Profibus so i've set both resister switches to "on".
The module connected to the "bus" is an IM178 motor module.
The module is giving me a SF an BF (Slave & Bus) Failure.
And Also The Plc is showing me the same faults.
