I'm using an ETZ 510 module to build a connection between my TSX Micro PLC and ETHERNET network. I have used Factory Cast Configurator to transfer my own Web site to ETZ 510 module. The Web site contains applications to control the light system of my customer's house. And from a PC on same ETHERNET network with ETZ 510, I can open that site. But now my customer wants to open it from INTERNET. I don't know how. Can anyone help me?
