Retain variables

Retain variables

Hello,
I need a few zenon logic variables to be retentive, so they keep their value when the runtime is stopped and restarted again. Only defining them as retain variables seems to be not enough, they fall back to zero.
In the zenon var list I cannot find the property remanence at the Straton vars.
How can I make the vars retentive?
