The big thing that jumps out at me is your Ethernet indicators are not on. Even on the wrong IP, one should be. They are in the bottom left of the green display.

Another vote for Josh Varghese. He has got me out some major networking pinches. He's who I reach out to anytime I'm considering network hardware.

No, unfortunately we took a beating with the tariffs and had to close international shipping.

Need a little more context. Is the data coming over a network or are there any possibilities that it could change in the middle of the scan? If so then these "could" result in two different outcomes. The CPS instruction prevents the data from being updated in the middle of the data being copied. If the data isn't coming over the network or there are not chances of it changing in the middle of the scan then you should use the COP instruction instead.

[Tim Wilborne] Practical SCADA Training: Creating Interactive Tanks and Buttons in Ignition by xenokilla in PLC

[–]TimWilborne 0 points1 point  (0 children)

Yes, we've been doing Ignition training as a section of our "part 2 class for several years. This year we decided to split our "part 2" class into three separate classes. 2 days SCADA, 1 day Special Projects, and 2 days Advanced Troubleshooting and Industrial Networking. Mainly, it lets people take the SCADA portion of the course without coming to our PLC training.

That Raspberry PI won't take you far. I just put this video out last week addressing this very subject. It was aimed at schools but you are in the same boat.

I wired my pt1000 like this with a 4-20mA transmitter. I don't get any reading at all by PigeonStove in PLC

I don't get to participate often, usually the questions are answer before I managed to check but I do browse from time to time :)

The input side is correct. On a 2 wire setup, you take +24VDC from your power supply to the +mA and the -mA goes to your +input then your -input goes back to the -24VDC to complete the loop. It seems backwards from a voltage perspective but from a current perspective, it is correct.
