Mitsubishi HMI IP Label question

Hello,

Can anyone tell me how to change the IP label for a GOT?

I am networking a bunch of GT1665M's and they automatically generate an IP label NewGOT1, New GOT2, etc. When I go into the communication settings under Gateway, I can click into the IP Label field but it will not allow me to edit this. I just want to name them based on what machine they are on instead of having to match up the IP addresses.

Thanks,

Dave
