Siemens SIMATIC NET S7-300 User Manual

7 Programming FCs (Functions) and FBs for S7 Ethernet CPs
A-215
S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
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.
