SAVE_PARAM: Saving adjustment parameters
Introduction When modifying the module’s (or built-in interfaces’) adjustment parameters, the
SAVE_PARAM instruction allows you to save these new parameters and substitute them for the initial parameters.
These parameters replace the initial defined values with the help of the configuration editor (or of the last save ).
The SAVE_PARAM instruction is the equivalent to the order Services → Save parameters
Note: During a cold start, the current parameters (not saved) are replaced by the initial parameters.
