My PLC is connected but I am not receiving any data


Looks like you haven't added any tags. What is your PLC brand and model?

siemens 400

You need to manually configure tags, you cannot drag and drop for that model.

is it like that? by the way don't know what I'm doing that's why I need assist.

Can't see your OPC item path in the screenshot.

I haven't touched an S7-400 in 5 years, probably can't help much further sorry.
