[Zenon Energy] Command processing

[Zenon Energy] Command processing

Dear zenon Team,

I am currently following the online course "Zenon Basic Training - Energy" and have reached the chapter on Command Processing.

When using the provided Training Project with the simulation running, everything works as expected. When I click on a disconnector symbol, I am prompted to select either Open or Close, and the command is processed correctly.



However, when I apply the same configuration in my own project and follow the same steps, but without a simulation or a PLC connected, clicking the disconnector symbol does not display the Open/Close selection dialog. Instead, the Command Processing window opens and the command status is shown as "Invalid".

I would like to know whether Command Processing requires either:
  1. a running simulation, or
  2. a connected PLC (or another device) with writable variables
  3. a symbolic address associated with each variable
in order to function correctly.

Below a screenshot of the only element that differs from the Training example:


Below a screen of the result I get on my adapted project:


Have I missed any additional configuration that would allow Command Processing to work in an offline environment?

Thanks for your help.

Kind regards,

Paul
