Ethernet connection

Hello! I am going to set up an ethernet connection between two plc,s. One plc is 315-2 DP with a 343-1 card, the other one is a 315-2 DP with a 343-1 lean-card.

I have been told that you can do this and send and receive in both plc,s, but you only have to program in the one without lean-card....

Can anybody explain, show example of how this is done, what blocks to use etc...
I would appreciate it alot



regards Orense

If there is a SEND block in one of the PLCs, then there must be a RECEIVE block in the other PLC.
With PUT/GET in stead of SEND/RECEIVE you should be able to make data transfers where the communication partner is passive.

You can configure a UDP-connection in netpro(in both PLC's) and use AG_SEND & AG_RECV to send/receive data over the configured connection. This works in both directions.
