RGM Variable and Zenon Logic

RGM Variable and Zenon Logic


I want to read a RGM Variable ( Last Recipe Selected), from Zenon Logic.

In Zenon Supervisor, after having declared the RGM Variable, I have cheked  "Visible by other program" on the section Parameters 61131-3 of the variable. I modified the length of the chain: 255

The variable was created in Zenon Logic.

If i select a recipe on the Runtime, the variable in Zenon logic remains empty ('').
Are there other parameters to configure to read a RGM variable on Zenon Logic or Zenon Supervisor?
