• Cause 3 of incorrect wiring: The wiring for the start port of the ring and the wiring for the end port
of the ring are reversed.
Check that the wiring for the start port of the ring and the wiring for the end port of the ring are

In the example below, reconnect the cables that are currently connected to X2 and X3 of the
Junction Slave to X3 and X2, respectively.

Review the wiring so that the last port is used for the output port of the Junction Slave in the ring
topology.
