With S7-1200 and S7-300 there are no problems...But with S7-200 I don't know how must I configure the PLC for enable the communications. I found some information on Support about how configuring the OPC Server (the syntax to read a variable from memory V). I did it so it's explained, but it doesn't work, so I think the problem is a wrong configuration on S7200. I have the module and I can program through it, but nothing more. What I want to do is really easy. I want to read one variable (dint) and one bit state on OPC Server. Can anybody help me? An example shoud be usefull... Thanks.

It's very good, but I think my problem is on my network card configuration. When I make "IPConfig" I have two different IP adresses, and with the Station Configurator, it takes an IP Adress thay I don't know... I'm going to test with another industrial PC (PC577), with this example and I tell something. Thanks a lot. I keep informed. Attachment Consulta.JPG (171 Downloads)
