Cycling Node Status
Using the Cycling Node Status parameter, you can easily determine
the status of any POINT I/O modules with which the adapter is
experiencing problems. A corresponding text string appears, including
the MAC ID and a description of the status code reported in the Node
Status Table. For more information on the Node Status Table,
see page 2-23.
