Hi Bernard, Why don't you use OPC to connect to your PLC. I'm guessing that you are using an Applicom Eth board to connect to your PLC. National Instruments has OPC servers for the following Schneider PLC's:
Schneider April 1000 PLCs Ethway (Applicom PC2000ETH) Schneider April 1000 PLCs FipWay (Applicom PC2000ETH) Schneider April 1000 PLCs Jbus (Applicom PC1000) You can buy these servers at National Instruments. Please check the link below: http://sine.ni.com/apps/we/nioc.vp?lang=US&cid=4584 You can connect to the items of the OPC server trough datasocket from LabVIEW using the OPC protocol. Check out this link: http://zone.ni.com/devzone/conceptd.nsf/webmain/DF8C0A4BA2E2B22A86256A3700592BEA?opendocument It could be that you already have an OPC server provided by Schneider. You can connect to the items exported by that server trough datasocket. If you know the path to the item It's very easy. Kind regards. Joris Vanderschrick Applications Engineer NI Belgium
