I have a machine running at a customer site. Great. (it happens to use an ATMEGA128 which is why i'm posting this at avrfreaks)
It has an HMI interface that can be accessed from the internet. HOWEVER, the site has a dynamic IP. So I have a computer down there running the DYNDNS client software, and I use a domain from dyndns to be able to accessed the machine. The HMI does not provide any tools to update a dynamic IP.
However, if that computer running the client software goes down (or goes to sleep), then when the IP address changes, the domain doesnt get updated.
OK, that sucks, but what is worse is that in the future I dont want to put a computer down with every machine.
I am using the XNUT-100 from proconyx. It has an ethernet port. Does anyone know how I can update the new IP address straight from the controller so I dont require a computer?
Alternatively, is there a din rail mounted device that can acts as a host for the DYNDNS client software?
