Reference
Port numbers are assigned to bit addresses in the PLC in units of 16 points, starting from the
channel corresponding to the node address set with the DIP switches.
(This does not apply if a configurator is used to assign port numbers.)

(NN) CH and (MM) CH as indicated above represent PLC channel addresses corresponding
to node address nn.
As for nn, nn+1, nn+2, etc., bit addresses corresponding to each node address are occupied
in accordance with the numbers of I/O points used. Accordingly, exercise caution to prevent
node address duplication.
