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.
