Method for controlling time based signals to indicate a time range free of an end time

A method for controlling time based signals that are outputted from at least two processes of a unit, which comprises the steps of:

• converting at least one first signal into a first signal value and indicating over a first time range of a first process with a first defined start time and a defined end time, in which a present time is signalized by a spatially extensible and uniformly highlighted portion of the first time range defined between the first start time and at least the present time;
• and
• converting at least one second signal into a second signal value and indicating over a second time range of a second process with a second defined start time and free of an end time, in which the present time is signalized by a spatially extensible portion of the second time range onto which a variably highlighted and superposed section is overlaid, the variably highlighted and superposed section being defined between the second start time and the present time.
