hi! need some help here. we recently installed a motor protection relay from AB (825P) and needs it to communicate with the existing yokogawa PLC. the yokogawa plc is using profibus as its comm protocol while the AB 825P is in modbus. to solve this problem we put a gateway from prosoft to make the profibus communicate with modbus. i have configured both the 825P and prosoft 4105MCM PDPS unit, while a guy from yokogawa did the configuration to get data from the 825P. we got them communicating but the problem is we cant get some data correctly from the 825P. some data are correct like the ave voltage and line frequency. but the real power (kW), ave current and power factor have a big discrepancy from the ones we see in the 825P unit. can anyone suggest what might be the problem and how i can we fix this problem? thanks a lot!
