Precautions for Configuring a Ring Topology
The precautions for configuring a ring topology are described below.
a. If you use a Junction Slave in a ring topology, connect the last port of the Junction Slave to the
input port of the next slave to connect to in the ring topology.
The last port is the last to receive communications frames among multiple output ports on a Junc-
tion Slave. The last port is X3 for the GX-JC03 Junction Slave.
b. In the slaves that are connected in series from the start port of the ring in a ring topology, connect
the output port of the last slave in the ring topology to the end port of the ring.
The above examples of a and b are given in the figure below.
