The modes component is saved in the instance DB as follows:
Structure

Example:
By setting MOP.MAN once, the mode changes to MANUAL. This can be set either
controlled by the program (for example action in the sequencer) or by the PG
function "Modify Variable" or using an operator panel.
Activation Time
The following component consists of a structure containing information about the
activation time calculation. This is only evaluated internally by the system.
Structure
