We currently have a network in our plant, which connects Philips PC20 plc's. Each PLC has a CI (communication interface) card, which supports RS232. The messages send from/to a PLC are now going through a LOCAN network, once made by CFT Philips. This network is absolete and I am looking for a solution in renewing this. I was think of replacing the LOCAN boxes at each PLC site with a new box, which convert RS232 to TCP/IP Ethernet and vice versa. But the box should look inot the message whcih has a kind of address in the second byte. This adress should be converted to an ip-adres and the message should be send there.
Can anyone suggest such a device. Most of the devices i have seen only convert rs232 to tcp/tip and cannot be dynamically address messages.
Sincerely yours,
Harry Friemann
