I have a question. I am trying to VPN into a HUGE network with thousands and thousands of PLCs and a handful of robots. I usually program on site via the service port, but need to do it via the KLI remotely to solve an issue a thousand miles away.
I can ping the robot just fine, and the robot talks to the PLCs on the network just fine as well. An engineer there told me that he can't browse for any of the PLCs as well and need to connect via IP.
So my question is, is there a way to connect via an known IP address, or is there anything else I should look at? Any experience with huge networks In this case, huge means across the globe connecting probably 100 facilities.
Thanks
