Is it possible to use any other tool to change the ip than Step7, i remember that i saw this kind of sw somewhere some time ago?. I have 'fixed' IP parameterized from the private adress range, but from our office i must have the clients public ip set to the adress of the CP to be able to communicate with the plc/cp. Now if i change the private ip and try to download it, i suspect that it does not work. Or is there another way to do this?. The client has no knowledge or tools for Step7.

This will help your customer, but it will not work over a remote Network, because it is MAC based. About the second question, I guess you use Port forwarding, don't you? If so why should you not be able to download a HW Config with a new IP Address in it? You are right, if you want todownload you have to set the public IP of theremote Router as the Endpoint but the Router willforward the Traffic to the CP and than to theCPU. It surely does work,but you will have to be aware that due to the Port forwarding the Connection to the CP will be lost as soon as the CP has its new IP Address. Then the Router on the remote side has to be configured that way that the new IP of the CPis set as the Endpoint for the Port forwarding. Than you have connection again. Best regards J_Bell

I have also remote access to a PC at the site which is at the same network that the PLC, so i could make the parameterization with that. I am not using port forwarding at 'my' end, i have only set the public ip at hw config and then translation, then i am able to connect to the remote plc. At the clients end there is port forwarding, made by a local company that takes care of our customers HW / SW / NW-needs. Maybe i can manually add a route so that when accessing the private ip it would be routed to clients public ip, i have never thought of this, my knowledge is mostly in programming, not networking. Best regards, Raimo

If they know the new IP they will surely change the setting for the Port Forwarding in the Router. Best regards J_Bell
