Ensure that the Profibus option is installed on the robot side (check the Fanuc robot communication options in the MENU settings). The PLC uses OpcOn (Bosch Rexroth) as the master.
Fault Phenomenon: PROF-017 STOP.G Slave Disconnected. Communication disconnection abnormal alarm, check the alarm interface on the teach pendant. Fault Causes:-1. The DP slave’s cable of the PROFIBUS circuit board in the robot controller is not connected.-2. Communication with the DP master has been cut off.-3. The configuration data of the robot’s DP slave does not match the configuration data set on the DP master.-4. The parameter data of the robot’s DP slave does not match the parameter data set on the DP master. Solution:Reconnect the cable or replace the damaged wiring.Confirm that the DP master operates and can communicate with the DP slave.3 Change the robot’s DP slave settings to match the configuration data or change the DP master’s configuration data for the robot’s DP slave.A Change the DP master’s parameter data for the robot’s DP slave.-5. For the robot’s PROFIBUS slave, be careful to avoid the “PROF-003 STOPG Slave Configuration Data Error” and “PROF-004 STOPG Slave Parameter Data Error”.Precautions: To mask the PRIO-017 alarm, enable the sixth item ERROR ONE SHOT in the Profibus settings interface (single error reporting). During normal production, this item must be set to disabled.
