MikhailModeratorI suggest to follow the videos. If something is not clear in the videos, please ask a particular question.
MikhailModeratorOn the screenshot you can see that Modbus RTU is used. But in the settings there is Modbus TCP. Seems that the screenshots were made in different time with different settings.
What Modbus type is needed, Modbus RTU or Modbus TCP? What is written in the device manual about that?
MikhailModeratorDoes PAC3200 use Modbus protocol?
Could you make screenshots related to the issue?
