Open TCP/IP Communication

[Engg_Ice 0]

Hi all, How to frame message to exchange data between 2 device that supports open TCP/IP coomunication confined with IEEE 802.3 standards. My case is to exchange data between Siemens S7 CP443-1 and AB 20-COMM-E module. Making connection and hardware configuration in siemens is clear. But framing message is not known. Please help. Thanks

Thats a mixed bag and probably not doable with the hardware described above. AB 20-Comm-E speaks Allen Bradley Ethernet/IP S7 CP443-1 does speak a lot of different ethernet but Ethernet/IP is not one of them. I think you need either a gateway product between the two devices from Prosoft http://www.prosoft-technology.com/content/view/full/3238 or Route the 20-Comm-E card messsage to a AB processor and use an 1756-EWEB etherent card talk to the S7 CP443-1. Is that CP-443-1 the advanced ethernet card? If it is then you can do this route.
