Dear all

I downloaded Ignition Maker edition and everything works well. for Now the first step is to connect my PLC to Ignition OPC UA server. the PLC mark siemens S7-1200 connected to Internet and I have the IP address. so Please I need Instruction to connect the PLC to the server.

Here may be a good place to start.

Also, going through the free video training at Inductive University should be worth while.
