So this may be a rudimentary networking question but when I am programming a touch Panel that is connected to our "in house network " I can program through the network and the units are currently setup to obtain IP through the DHCP method. This also is the case when installing to our other facility. When in that building and connected to the network I can see the panels and program to them and everything is gravy. I would like the ability to be able to connect and/or program to the remote facility from our main network. The remote facility is about 100 miles away and so it would be nice to be able to make program changes and updates with out having to go out to the site. Do I need to assign a Static IP for this? Is this a firewall issue? Any help would be great.

Do you have connectivity between the networks? I assume you do, and hopefully have a different IP addressing scheme at the remote site.
The issue could be that the discover packet that the software sends out would be UDP, which does not cross routers by design. If you have static addresses you should be able to connect to them because it would be a point to point connection, without having to go through the discovery process.

Yes it is a "rudimentary networking question ", but there are many difficulties when trying to connect to this type of device via the internet - mainly firewalls in local routers & IP address issues.
A good expert on networking should be able to help you through this, when I was trying to do what you 're doing, it ended up being a collaborative effort between myself & our computer programmer. The remote panel (or router to which it is connected) needs to have a static IP - because IIRC that is the address which your local panel/PC/PLC looks for & it needs to be static.
We ended up with a router at the remote site which was configured to direct the C-more ports to the local IP of the Cmore, with no firewalls, it is somewhat non-secure in that anyone on the net can access the IP. This was before the latest Cmore upgrade with remote CONTROL access, so really our only risk was that someone with Cmore software could re-program the panel via the internet. (Since the PLC is configures such that the panel is not critical to machine operation, this is not a big risk).
