It might seem like a stupid question but please let me elaborate.
I had a PLC that already had some IP address on it which I needed to change. My initial thought was to just make a hardware configuration with the new IP address and download it to the PLC.
What I though was - When I download the new hardware config I'm telling the PLC "this is your new IP address"
A much more experienced friend of mine said I can't do this, because I won't be able to download the hardware config since the IP address I set there is not the same like the actual IP address of the PLC. He claims the IP address in the HW config is saying "download the HW config on this IP address".
So his solution is to install a new CP, give it some IP address, and then download the HW config from there.
Please tell me who is right? Probably it's him, but I find it hard to believe there is no simpler way to do this. What if you don't have a spare CP? It seems logical that you should be able to tell the computer both information, "connect to this IP address and change it to that IP address". Like you would do with proneta.
