Status Area and Troubleshooting
Section 10-2
Note Stop the data link from the node at which the LNK indicator is lit (indicating
active data links). Data links cannot be stopped from nodes which do not have
active data links.
10-2 Status Area and Troubleshooting
The status of the Unit and the communications status of the Controller Link
Unit is recorded in the Status Area of the PLC. The cause of errors can be
found by searching the Status Area. The Status Area can be read using a Pro-
gramming Console, the SYSMAC Support Software, or the Controller Link
Support Software.
This section explains the contents of the Status Area and tells how to trouble-
shoot errors recorded there.
10-2-1 CS-series Controller Link Units
The status of the Unit and Network is indicated in the following manner in the
PLC.
Status information related to duplex operation of Communications Units is
reflected in the PLC’s Auxiliary Area. For details, refer to 10-1 Troubleshooting
Using Indicators and Auxiliary Area on page 259.
