When using the functions AG_SEND and AG_RECV, data is transported to the communication partner via the
Ethernet bus of the CP. The communication partner is configured in STEP 7 in the "NetPro" tool.
The special feature when calling the functions involves the specification of parameter "LADDR" at the named
blocks. In the case of SINUMERIK 840D sl, value W#16#8110 must be connected to parameter "LADDR".
In the basic program, this function is available under the FC number 1005 (this FC corresponds to the FC number
FC 5 in the library "SIMATIC_NET_CP").
The block can also be used in a SIMATIC-CPU 3xx with CP343-1.
The protocols TCP and UDP are supported. TCP is the preferred protocol.
Note
With the function AG_SEND, parameter ACT must be TRUE until a result is signaled in
DONE or ERROR.

13.13.31 FC 1006: AG_RECV receives data from the Ethernet CP

Function
The FC block AG_RECV receives data transferred via a configured connection from the Ethernet CP.
The specified functions correspond to the functions of the library "SIMATIC_NET_CP" of the S7-300 CPU in
STEP 7. In general, the online help of these functions applies for these functions and therefore a detailed
description is not provided here.
The functions AG_SEND, AG_RECV can be used for data exchange with another station via the integrated "CP
840D sl".
