Communication from AC 700F to Simens DP/DP-coupler fails
I'm trying to communicate with a Siemens DP/DP-coupler from a AC 700F and a CI 773F communication module but Freelance is indicating Configuration Error on the slave. The following Standard diagnostic bits are set: StationNotReady, CfgFault, ExtDiag, PrmReq. MasterAddr is 255.
The slave configuration is supposed to be 0x40, 0x3f, 0x40, 0x3f, 0x40, 0x3f, 0x80, 0x3f, 0x80, 0x3f, 0x80, 0x3f ( 3 x 64 bytes inbut + 3 x 64 bytes output)
If I select View rel configuration on the slave it says 0xc0, 0x7f, 0x7f
I have set number of bytes per slave to 192 bytes input and output. The diod STA is flashing orange on the CI 773.

The problem is found. The system in the other end (not an ABB system) failed with the a reconfiguration of that part of the coupler and the inconsistence caused the failure in the Freelance system.
