Is disconnecting and reconnecting nodes without hardware errors possible?

vidarv Posts: 66 Rating: (1)	We are doing some trials with a 416 CPU and different ET200S nodes on profibus DP. The nodes is being connected and disconnected from trial to trial. Example: 1. trial 416-DP CPU and Et200S node 10 and 11 connected Hardware config includes all modules above 2. Trial 416-DP CPU but only Et200S node 10 connected. Hardware config includes all modules as in trial 1. We get errors in PLC diagnostic buffer because node 11 is not present, OB82 handles the error and avoids PLS stop. We are looking for a way to disconnect and connect nodes as in trial 2 without such errors!? Is there a way to ignore disconnected nodes and thus avoid errors in PLC diagnostic buffer? Any ideas anyone?
