7.5 FC 10 AG_CNTRL
How It Works
With the AG_CNTRL function, you can diagnose connections. When necessary,
you can initialize connection establishment again using the FC.
The following actions are possible by setting commands:
Reading out connection information
Based on status information, you can decide whether or not it would be useful
to reset all or individual connections of the CP.
Resetting configured connections
You can reset individual or all connections of a CP.
The commands of the AG_CNTRL function (FC) are permitted only for
SEND/RECV connections based on the ISO / RFC / TCP / UDP protocols.
