I have a customer who will want to access his HMI at a remote station via the internet. He has gotten internet service installed and has asked for a fixed IP address to facilitate this.
This little control system will have a Micrologix 1400 and Red Lion Graphite HMI.
I expect I could give the HMI the fixed IP address, but then I'd have to connect to the PLC via a different port. I think it might make more sense to use a router in the panel, keep the HMI and PLC addresses private, and let the router do the network address translation to and from the fixed IP address.
Can a managed switch do this or do I need a router?
Any suggestions for a reasonably priced DIN rail mount router?
There will only be one other device using Ethernet at this station, two if I am plugged into the local network with a laptop for commissioning, so 4 ports is enough.
Thanks,
Paul
