I am using the Uno for school, and I ran into an issue where the analog outputs (holding registers) don't display data or hold data. I am using ScadaBR to build views and display the values from various outputs. I am using MODBUS over RTU and building ladder logic in OpenPLC Editor.
For reference, I am expanding the design in the video below.
The counter in the video is the starting component in a model of a nuclear reactor.
Earlier this week I had an analog output (holding register) reading correctly a value from an up-counter current value. Yesterday it stopped displaying a value.
I am using another analog output (holding register) to write values to a max counter. This value is fine because I can see my changes when I use a ScadaBR component to track the change, it displays fine.
I am at my wit's end with this. I would appreciate any tips.
I have merged your topics due to them having too much overlap on the same subject matter @cybershell.
In the future, please only create one topic for each distinct subject matter and be careful not to cause them to converge into parallel discussions.
The reason is that generating multiple threads on the same subject matter can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.
