SPK107 OWEN and ATV312 Schneider Electric (working Modbus RTU circuit)
Task was set to create application software for the panel of the company "Owen" SPK107 messed around for quite some time. The thing is that separately, these devices work well
Research and production company "Centrifugal Systems" set the task to create application software for the SPK107 Oven panel. The solution didn't work on the first try. The point turned out to be that the panel and the altivar work well separately, but when connected, they refuse to see each other, and both have Modbus TCP in the specification. I put 120 Ohm terminators, picked up different wires, but here's an ambush - they refused to work together in a bundle. After carefully reading the documentation from Altivar, I realized that it was necessary to install not only a resistor at the two ends of the line, but also capacitors.
It was unbelievable, but...Attention!!! Installed all this exactly - it worked)
Here I post the algorithm that needs to be executed to make it work:
