PLC Connection Using Host Name instead of IP Address

Ignition
1

Hello. I have a CompactLogix PLC that is going to be on a portable test skid. It will be plugged into the network wherever it happens to be at any given time. The consequence of that is that it will bounce between subnets and have a dynamically assigned IP address. I have always used IP address when setting up a PLC connection in Ignition.

I tried connecting to a test PLC using its host name instead of IP address but didn’t have any success. Has anyone make a PLC connection like this before?

Thanks for the help!

I think that’s only for database connections, etc, not PLC drivers.

I’ve never used a NATR, but that or a router, upstream from the PLC, as part of the skid, with a static IP, handing out the DHCP to the PLC. Hit the static of the NATR/router and internally forward to the PLC.
