Siemens SINUMERIK 840D sl Function Manual page 1331

Functions AG_SEND, AG_RECV
The named functions correspond to the functions of the library "SIMATIC_NET_CP" of the
S7-300 CPU in STEP 7. In general, these functions are valid for the online help of these
functions. The functions AG_SEND, AG_RECV can be used for data exchange with another
station via the integrated "CP 840D sl".
There are a total of 5 functions for the "AG Functions"
1. AG_SEND, (SINUMERIK 840D sl)
2. AG_RECV, (SINUMERIK 840D sl)
3. AG_LOCK, (currently not implemented)
4. AG_UNLOCK, (currently not implemented)
5. AG_CNTRL. (currently not implemented)
The 3 functions mentioned last are currently not available for SINUMERIK 840D.
Note
For the function AG_SEND the signal sequence for the parameter ACT is currently displayed
wrongly. ACT must be TRUE as long as an event is reported in DONE or ERROR.
When using the functions AG_SEND, AG_RECV a data transport to the other point takes
place via the Ethernet Bus of the CP. The other point is configured normally in STEP 7 in
NetPro. The special feature in the call of the functions lies in the specification of the
parameter "LADDR" to the named blocks.
In case of SINUMERIK 840D sl the parameter "LADDR" must be filled with the value
W#16#8110. In the basic program, these functions are available under the FC numbers
1005, 1006, 1007, 1008, 1010.

These blocks can also be used in a SIMATIC-CPU 3xx with CP343-1.
The protocols TCP and UDP are supported. TCP is to be preferred.
Note
Other communication blocks, such as BSEND, USEND, which possess a CP343-1, are not
supported in SINUMERIK 840D sl.
