Hi,
I am using a DP DP coupler (as slave) between two ABB controllers (Masters).
During configuration:
In Master 1 the first module is 32 bytes read and in Master 2 the first two module is 16 bytes write.
When tested data transfer seemed to be working good.
But when we Remove the profibus plug for Mater1 and put it back the unit does not start communicating on its own, changing the termination resistor status or taking off the power makes it work again.
Any help would be appreciable
