While I await IT’s plan for some type of converged ethernet architecture in our plant or approval to buy good networking hardware at the machine level. I bought this router. To try and get one of the 30 machines, with more or less the same config, I have online.
50 bucks and claims to do what I need. Has a pretty cool web app that gives access to the os to make all the rules and whatnot.
These machines, par for the course, all have their own network. In the default range.
192.168.0.1 – PLC
192.168.0.2 – HMI
192.168.0.11 – Keyence GT2
192.168.0.10 – SMC air manifold
With everything going back to a cheap unmanaged switch.
So the idea was to try and set up 1:1 NAT translation (192.168.0.1 → 18.104.22.168) As cheap as possible so I can get ahead of the game and have something to develop against. Even if it’s somewhat unreliable. Or better yet it proves to be reliable and we save a but load of money. Not holding my breath tho.
So got the router set-up, I should preface this, and say I don’t really know what I am doing. Up until I found ignition I mainly did web dev as a hobby and robotics programming. And we have useless 3rd party IT support.
Then tried I to make a connection to the PLC. (CompactLogix L16ER Rev 20.19) . Watching the router it seems like it may try to connect. It will TX some. I can see the activity on the router. So I took a capture to see what is going on… But, its a bit cryptic to me. Looks like its getting rejected? As always any guidance, words of wisdom, encouragement is appreciated.
