Monthly Time Scheduler Channel (nth day of the month)
With the Monthly Time Scheduler Channel (nth day of the month) it is possible to define a switching-event on a single day of the month in multiple months of the year.
Settings
- Start: Time: Absolute start-time on a switching-day. The scheduler-channel will be active beginning with this time.
Start: Sunrise + Offset: The scheduler-channel will be active beginning with the actual sunrise + offset (in minutes) on a switching-day.
Start: Sunset + Offset: The scheduler-channel will be active beginning with the actual sunset + offset (in minutes) on a switching-day. - End: Time: Absolute start-time on a switching-day. The scheduler-channel will be active beginning with this time.
End: Sunrise + Offset: The scheduler-channel will be inactive beginning with the actual sunrise + offset (in minutes) on a switching-day.
End: Sunset + Offset: The scheduler-channel will be inactive beginning with the actual sunset + offset (in minutes) on a switching-day.
Series Model
- Always on the nth of: The explicitly selectable switching day (1st...31st).
- January...December: Selectable switching-months.
Behavior
In contrary to the daily and weekly scheduler-functions, the switching days are explicitly named. There is no periodicity to be calculated, which depends on the PLC-init-time.
If the daytime of the start is lower than the end, the scheduler channel will only be active from the start-time until the end-time of the switching-day. If the daytime of the end is lower than the start, the scheduler-channel will just work inversely. Entering the same time for both start and end would result in an undefined-state and will thus be regarded as an input-error.
It is also possible to use the sunrise/sunset function which will calculate both times for the switching-day together with an offset, which can be either positive or negative. These resulting start and end-time however are automatically delimited to the beginning (00:00:00:000) or the end of the day (23:59:59:999).
Scenes
On this screen the scenes can be entered, which shall be executed, when the scheduler-channel turns to either its active or inactive state.

State
- Value: Displays the current state of the scheduler-channel.
- Remaining Time On: Remaining time in which the scheduler-channel is active.
- Remaining Time Off: Remaining time in which the scheduler-channel is inactive.
State PLC Module
- Execution State: Shows if the module is running or stopped.
- Error: In case of an error, the error code and the error parameter are displayed in this box.
- Start/Stop: Starts/stops the module.
