hello,

currently trying to learn ignition for just general knowledge of a new environment. Trying to connect the maker edition to my s7 1200 trainer. I’ve made the opc connection and it displays connected. When I create the tag however I get back a “Bad” gateway connection and the tag isn’t seen. I’ve used tags like Mx0.0 so not sure what I’m missing or need to change. Any help would be appreciated

Also do I need to change anything here or is the default OPC server good?
