Can I test the availability of a slave with the BT200 (6ES7181-0AA01-0AA0)?
Yes. The BT200 scans the complete bus for users with the message "FDL_request". All users that respond are displayed on the BT200.
- Before testing, all PROFIBUS DP masters must be removed from the bus.
- The bus terminator must be assured.
- All user addresses must be unambiguous.
