Timer/Scheduler

APPLICATION

The Timer/Schedule block can be used for timed circuits and timed setpoints. It can be used in a digital mode (so switches on and off) as well as in an analogue mode (different values for different times).

In addition to the weekdays other switching times can be defined for holidays and other operating modes. You can edit the schedules through the user interface either on the apps or the webinterface.

Basic Programming

Settings – Digital

Double-clicking on the block opens the processing window in which the switching times can be defined. Use the left mouse button to click on the desired start time, hold down the mouse button and drag to the right until the desired switch-off time, then release the mouse button. The switching time is now highlighted in green.

During the selected time, output AQ goes ON.

You can find information about the timer in connection with operating modes here.

Time Switch – Analog

The timer can also be used to output analog values. To use the timer with analogue outputs, you must deactivate the field “Use as digital output” in the property window.

Double-clicking on the block opens the processing window in which the switching times can be defined. Use the left mouse button to click on the desired start time, hold down the mouse button and drag to the right until the desired switch-off time, then release the mouse button. The switching time is now highlighted in green.
In contrast to the digital timer, you can now set a value to be output at the output AQ at the switching time. The standard value is output outside the switching times.

Advanced features

Additional activation

In the lower area of ​​the edit window you will find the checkbox “Activation required”. If this checkbox is activated, an additional pulse must be applied to the Tr input during the switching time so that the timer activates the output AQ.

If a pulse is applied to the input R (reset) within the switching time, the output AQ is prematurely deactivated.

This is useful, for example, when controlling the entrance doors of a store.
No employee present (eg due to illness) – Door remains locked!

The current mode is output at output AQm. The mode number is also displayed in the edit window behind the mode.

Manual mode

If, for example, parameter “A” is set to 1 and parameter “M” is set to 4, the timer operates according to the settings of mode 4 (value in brackets). In our case, this is Tuesday.

Inputs

Tr TriggerRequired only if ‘Activation required’ is set.
RResetPerforms a reset of the activated time window and sets “Q” to 0 as long as “R” is on.

Parameter

RRemanenceIf ON, the remanence is activated
AAutopilot Mode0 = active, 1 = manual mode
MManual ModeA mode can be selected using this parameter
TContinues Output PulseSets the duration for the output pulse to AQ when ‘Activation required’ is set

Outputs

Example Programming

In this example, a new calendar entry called “winter time” was created and linked to the user-defined “winter time” operating mode (selectable under Type).

The newly created operating mode was then added as a new line in a timer and the switching time was defined.  If the checkbox is set to “Activation required”, the trigger input must receive a pulse in order to activate the switching time.

If this pulse is activated, the clock switches on and the Christmas tree light is activated. At 23:30, as set in the timer, the lighting is deactivated again.
