If the two nodes are healthy then i will not get BF indication in the DP master. If anyone is not accessable by master the it will generate the BF Indication. Is it possible to enable and disable the Profibus slave communication by program for DP master? Regards, Sankar

Note: SFC12 works over several OB1 Scans.
