Description
You can use the FC10 "AG_CNTRL" for connection diagnostics. If required, you can initialize a new connection setup via the FC10.
Fig. 01
The following actions can be executed via parameterizable commands:
- Reading out connection data
Based on the status data of all or individual IE CP connections you can decide whether or not it is useful to reset the connections.
- Resetting configured connections
You can reset individual or all the connections of an IE CP.
The FC10 "AG_CNTRL" commands are permissible for open communication services only with the following protocols:
ISO Transport, ISO-on-TCP (RFC 1006), TCP and UDP.
More information on the FC10 "AG_CNTRL" commands is available in the manual "Functions (FC) and Function Blocks (FB) for SIMATIC NET S7-CPs Programming Manual" in Entry ID 30564821.
The following commands for connection setup and clear-down are not supported by all IE CPs:
| Command |
Description |
CMD 6
"CN_DISCON" |
connection disconnect:
This command resets the connection which has been selected with ID and LADDR. The resetting of the connection is prompted by a connection abort. Any data saved in the stack is lost without notice. The connection is then not established automatically. The connection can be re-established using the "CON_STARTCON" control command. An entry is generated in the diagnostics buffer from which you can read the result of the command. |
CMD 7
"CN_STARTCON" |
start connection:
This command establishes a connection which has been selected with ID and LADDR and which has been aborted beforehand with the control command "CON_DISCON". An entry is generated in the diagnostics buffer from which you can read the result of the command. |
