This logic group signals, depending on the time, when the measured value falls below the specified limit value.

The time range is defined via the week clock. In the example, the time range is set from 8 am to 8 pm.
Thus, the first comparator is activated via the "GATE" input from 8 am to 8 pm, while the second comparator is deactivated (by the inverter tool).

The inputs "Default 1" and "Default 2" set the limit values for the comparators.
The measured value is transferred to the logic group via the "Measured" input.
