Is that GSD File is not matching?? or the Slave address itself not detecting?

1.Please refer to Signal Exchange List or Data Mapping List given by Third Party Vendor.
2.After Configuring that u can able to check the status in in Web Server,by seeing the hexadecimal Value for Slave and Master.

Similar problem faced for communication with S7-400 PLC of siemens.

As ABB side GSD installed and configuration done similarly Siemens side also done but not communicated. Then installed back version file in siemens library and used that.

In siemens system only we installed previous version hardware file but in ABB used current GSD. Now it it sommunicating.

So please check GSD files and in both side and if required change in S7-200 library and try once. Sometimes compatibility in version may cause problem. Please don this once if slave address is matched.
