Detecting errors in the CC-Link IE Field Network
Errors occurred in the CC-Link IE Field Network can be detected using safety refresh communication status. Create a
program using safety refresh communication status, which turns off safety outputs in case of an error.
■Safety refresh communication status
The following table lists the special register names and numbers to check safety refresh communication status for each safety
connection. If multiple CC-Link IE Field Network master/local modules are connected to the base unit, the number of the
special register varies according to the number of modules connected. The safety connection number is the one displayed as
"No" on the detailed setting window of the safety communication in the CC-Link IE Field Network master/local module.
