Firstly you need to open the relevant port in your corporate or home firewall to allow access to your internal network from the Internet. Your router or firewall blocks all incoming connections by default. If you are using your corporate network then your IT people will know what to do and you should consult them. The rest of this description is assuming you are using a home network. The port that your browser defaults to is port 80 but you can use any port as the firewall or router can map any incoming port you desire to the relevant port that the Logo is configured to receive requests from. If you need to access more than one Logo, you will need to use different port numbers so that your router will know which one to send your incoming requests to. Remember, you don't use your Logo's IP address, you use the IP address of your router. It states in the documentation that the port the Logo listens on is Port 8080 but this did not work for me and I had to open port 80 internally. I don't know why Siemens is stating port 8080, perhaps someone else knows. Next you need to either use a Fixed IP address from your Internet Service Provider (ISP), or register with one of the many DDNS (Dynamic Domain Naming services). This is because the external IP address that the router uses is supplied by the ISP and changes at their will. You therefore need a name, like http://joe.blogs.dyndns.com which you type into your browser and your browser looks up the DNS services on the Internet to get your current IP address. One other thing is to configure all your Logo PLC's to have fixed IP addresses so that your router knows where to send the request to. Once you do all this, all should work as I access mine over the Internet to monitor remote stations. I also have some of mine connected via wireless as it is impossible to run Ethernet cable to all my Logo PLC's. As I said before, if you are not using your home network, get your IT department to do it for you. Hope this helps Jim |
