Am I close, you buy a fixed IP address to a factory, you sit a server at that address running a webserver and sql database runing an opc web server connecting you to your whatever. I am going to have a go at that very shortly.
The part I fall down on and have little experience is using default gateways, can you buy routers that have mini websererves for logging in and allow them to be used as a default gateway for for another ip address.
Eg
I have a plc and touchscreen sitting on a ip network, the touch screen has a built in web server, if you are on the local network you can type in the ip address and naviagate with IE.
I want to be able to acess this through the fixed IP address to the factory from home to check the status of the plant.
If I could make program changes from home even better.
