I am a begginer and I have a application which need to communicate a PLC S7-1200 with Excel (VBA) through ethernet. Do you have a link with tutorial to do this? I search here, but I have dificult to find information which can be used by me. One more time: I am a begginer. Best regards

With _C blocks I expect only drag$drop each block to your code place and some instance DB will be created for block functionality. Because of new CPU firmw. I expect probably define own TCON_IPV4 connection/parameter DB where you need define each of parameters. Pls check everytime TIA help about your blocks used. Update: other 'bypass' solution is define also TCON block manually and use it for _C instruction as source for define connection/parameter DB.

I attached some screenshots, but as I said: I don't have experiencie, if you can explain step-by-step I appreciate very much! Solution: So, I just changed the firmware(on PLC) from V4.1 to V4.0 and works fine. Attachment Screens.zip (224 Downloads)
