with Q Series CPU, existing wiring can be utilized, and network parameter modification is not
required.
(2) MELSECNET(II) local station data link modules for optical fiber loop, coaxial loop, and
MELSECNET/B are provided to support all types of existing networks.
The following is an example of replacing one of A Series local stations with the Q Series.
