5.3.1 FC5 AG_SEND / FC50 AG_LSEND
Meaning of the Block
The FCs AG_SEND / AG_LSEND pass data to the Ethernet CP for transfer over a

The selected data area can be a process image area, a memory bit area or a data
block area.
Error-free execution of the function is indicated when the entire user data area
could be sent on Ethernet.
