When the master is in the the hardware config everything is ok, when the DP/DP coupler is added to the network the CPU goes into error and so does the profibus master module. The coupler shows system and profibus fault constantely regardless of the various cables, plugs and settings tried? The coupler is set with power on, diagnostics and automatic address off and various addresses tried. Two different couplers have been tried too.

I don't believe anything had been changed from one day to another so I wouldn't know what was causing the problem initially.
