While running this wizard which connection I need to define in Connection type. Also I checked backup which I got from Forum. Send and Recieve blocks are called in Different CPU's. Then, it will become only one way communication. Or is it posiible to do both way communication? Thanks, Shailesh

One communications partner does active connection establishment and the other one is passive - it just waits for the active one to start. When the connection is established both communication partners can send and receive data, irrespective who started the connection establishment. Regards, Kaulquappe

When two PLC send/receive data they also have to encapsulate data with known protocol, I'm afraid that AB and Simatic they don't speak the same language. You can connect two different PLCs with some wide used standard protocol like Modbus TCP/IP, Siemens has sipport for it, there also shouldn't be a problem for AB.
