 Status 1 Tab Page
The Status 1 Tab Page shows the status that you can monitor with device variables for the CJ-series
Unit (i.e., Unit Status 1, Unit Status 2, Communications Status 1, Communications Status 2, and
Communications Status 3). The given status is TRUE if the check box for it is selected. In addition,
the Target Node Status Area shows the connection status of the target nodes that are connected to
the EtherNet/IP Unit as the tag data link originator. If all tag data link connections to the node are
established and normal, this information is displayed in blue. However, if any connection is broken,
this information is displayed in red.
