This is bogus. First, TCP/IP is NOT an application layer. The two devices MUST suport the same applicaiton layer. CSP, Modbus/TCP, EitherNet/IP are application layers. Second you don't need to set up a receive block in the SLC unless it is a master and request the data from the DVT.Take a look first at the DVT manual. Cognix vision systems can send data to AB via TCP/IP and setting up a receive block in the SLC is simple, I'd be surprised if DVT didn't have some function to do this also.
Peter Nachtwey said:DVT supports Ethernet/IP, SLC5/05 does not unless Rockwell recently added it. I don't know if the DVT supports the older CSP protocol the SLC uses. If you are using CSP then one of the two devices (DVT or SLC) needs to be a master and initiate the transfers.

Unregistered said:I *have* setup a SLC 5/05 and a Cognex vision system to exchange data over ethernet via tcp/ip via whatever. End of story.
This tells me unregistered user absolutely incompetent in this field.Who cares how that data got exchanged as long as it does.
