Broken or unconnected cable
The output ports are
connected to each other.
The following error message is displayed.
Correct the error as follows.
If you configure a ring topology, replace the broken cable or make other wiring corrections. If you
do not configure a ring topology, review the wiring to the X3 port of the Junction Slave so that
output ports are not connected to each other.
When You Cannot Identify Incorrect Wiring Points of Communications Ca-
bles
The following error message is displayed.
The correction for each cause of incorrect wiring is described as follows.
• Cause 1 of incorrect wiring: There is more than one ring topology.
Check that there is one ring topology.
You can configure a ring topology in only one location.
In the example below, there are two ring topologies in the actual network configuration. Discon-
nect cable (A) or (B) that connects output ports to each other to have only one ring topology.
