Manual VIPA System 300S SPEED7 Chapter 4 Deployment
HB140E - CP - RE_343-1EX71 - Rev. 09/46 4-33
At the PLC side for data transfer with these connections the VIPA handling
blocks AG_SEND (FC 5) and AG_RECV (FC 6) are to be used.
The following connections are Send/Receive connections:
• TCP (SEND-RECEIVE, FETCH-WRITE PASSIVE)
• ISO-on-TCP (SEND-RECEIVE, FETCH-WRITE PASSIVE)
• ISO transport (SEND-RECEIVE, FETCH-WRITE PASSIVE)
• UDP (SEND-RECEIVE)
Here the following parameters define a connection end point:
