Setting Connections
when Dividing IN Area
in Two
When a CS/CJ-series DeviceNet Unit is used as the master, the IN Area can
be divided into two areas by setting the connections. This function is enabled
by setting two connection types at the same time for a single DeviceNet Com-
munications Unit using the user-defined settings.
When a DeviceNet Communications Unit is used, one connection type can be
used to exchange data from IN Area 1 and OUT Area 1, and another connec-
tion can be used to exchange data from IN Area 2.
