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.
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]
63 stations max.
: Master station

Slave station number 01 to 77: octal
•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.
