dns resolution, vpn tunneling or ipsec?

[professor_jonny 1]

With CX1 you are limited to programming plc's via an IP address is this the case with CX studio?

Basically I'm asking if I can remotely program a plc via dns instead of a fixed IP address as all of our systems as attached to dynamic IP addresses provided by mobile routers and as IP addresses change all the time it makes communication harder to establish as I have to find out the IP address off the site before I connect.

By chance do these plc's have dns resolution or vpn tunnelling  so I can link them all on virtual network without setting up an private mobile network (APN) or using a vpn client such as a fortinet or cisco firewall box?

Sysmac Studio only offers a place to enter an IP address to get online.  Perhaps in the future they can consider it as an upgrade?

I was think that was the case but I could not see any where to set this info up, but a vpn server client setup would be awesome for linking sites.
