5.3.2 FC6 AG_RECV / FC60 AG_LRECV
Meaning of the Block
The AG_RECV / AG_LRECV function receives the data transferred on a
configured connection from the Ethernet CP.
The data area specified for the receive data can be a process image area, a bit
address area or a data block area.
Error-free execution is indicated when the data could be received from the
Ethernet CP.
Note:
Unless otherwise stated, all the following information applies to both the FCs
