How to resolve a field bus input disconnected error

If you receive an error on the robot teach pendant screen when you press play stating that there is a C207A0 Fieldbus Input Disconnected this is most likely due to someone having enabled one of the field bus protocols on the robot, either Profinet or Ethernet/IP.

Profinet and Ethernet/IP are protocols used to communicate between various devices and a PLC that is running either of the protocols. Unfortunately, even though the name Ethernet/IP sounds like it should have something to do with an ethernet connection for talking to the internet it does not have anything to do with the internet.

Error Message On Teach Pendant

To determine if this is the case navigate to the Installation tab on the robot teach pendant and then on the left-hand menu select Fieldbus. From there you can check both the Profinet and Ethernet/IP tabs. They should show as disabled, if they are showing a Yellow dot and that the adapter is Running press the Disable button.
