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 connections. This function is enabled by
setting two connection types at the same time for a single DeviceNet Commu-
nications 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.
The default connections and connection paths are shown in the following
table.
By setting the following connections as user-defined settings, the IN Area can
be divided into two areas.
