AFAIK there isnt a server or router, there are a number of SBC's which communicate with one another, then things like HMI's, remote I/O modules and VFD's on the ethernet network also.
Im certain im changing the ip address correctly, the hmi/touch screen is basically a computer with windows os on so im basically changing the ip address as i would on my laptop when im plugging into the network. Theres just something changing the IP address on boot up, the HMI is currently fitted and working but if i restart the IP will be reverted back to what it was and conflict.
Hope this makes sense,
Ahh i see, seems strange that something is changing the IP on start up though, is there some kind of network adapter BIOS? i.e. when the PC is booting does it say something like "press ctrl + N to enter network setup"? dont think that will be very likley but then i cant see why it would change a static IP address on start up..... may be worth ching it for viruses and malware etc... but again this seems unlickly as they are normally more malicious than just changing the IP address.....
