I hope this helps, hdhosseini

IN OB100 complete resart calling the Swr start FC100 and enter all the data for redundancy . But i have doubt in th FC100 DB_WORK_NO: DB1, DB_SEND_NO:DB2, DB_RECV_NO: DB3 mentioned db are not in the program that should be created by user or it will created as a instance DB. How to check that which cpu is in master state? ther is any status bit common in both the cpu. how to configure master & slave cpu status in HMI or SCADA. Kindly help me in this issue.

Yes, there are control bits and status bits for each CPU.Check the manual again. For last question , please check (Faceplate for operating and monitoring tasks) I hope this helps, hdhosseini
