9-4 Expansion of network
The JW-20CM can transmit data between 64 stations at maximum. If more than 64 stations are
required for data link, you can add communication stations with the procedure below.
(1) Multiple installation of the JW-20CM
Mounting more than one JW-20CM on the optional slot of the basic rack panel can increase the
number of stations.
[In the case of mounting 4 sets of JW-20CM]
• When installing multiple number of modules on a single PC, make them allocated so that
relay link area, register link area, and flag area may not overlap with each other.
• When installing multiple number of modules on a single PC, pay attention to the total
communication data volume and the number of bytes available for communication area.
• Though more than one JW-20CM can be mounted on single basic rack panel, they cannot
directly communicate with other stations beyond one network.
