Components > Control, logic & time > Operating hours mediator

The operating hours average is an invisible server component with the task of averaging the running times of loads that are controlled in groups as a 50% or one-third circuit. In this way, the controlled consumer groups are to achieve the same operating hours in total and thus the wear is to be evenly distributed across the group.

Note: The component does not function in the simulation, but only in server-client operation!

On the component, you can choose between group control with 2 or 3 switching groups. In this way, consumer groups e.g. in corridors can be controlled as a 50/50 circuit or e.g. strip lighting can be controlled in a three-phase circuit (L1-L2-L3).

Internally, the component has counters for the on/off time of each individual group. If a group is to be switched on, the group that has the lowest on-time is always switched on. If several groups are switched on and one is to be switched off, the group with the highest on-time is switched off. This principle ensures that the operating hours of the consumer groups are as equal as possible.

After an adjustable on-time in hours has been reached, a maintenance signal is emitted for the individual group. After maintenance has been carried out, the respective maintenance counter can be reset.

Data points of the component

Name	Type	function
Switch on all groups	Input	If an ON signal is applied to this input, all groups switch on, regardless of whether another input (All or Groups) requests a different switching state. This input has the highest priority.
Switch off all groups	Input	If an ON signal is applied to this input, all groups switch off, regardless of whether a group input requests a different switching state. This input has a lower priority than "Turn on all groups", but takes precedence over the group inputs.
Switch on group (A-C)	Input	If an ON signal is applied to one of these inputs, a correspondingly selected switching output group (A-C) switches on. The number of ON signals at the group inputs corresponds to the number of switched-on switching outputs.
Switch output group A-C	Output	Here, the switching signal for the individual groups is output.
Reset maintenance interval group A-C	Input	If an ON signal is applied to this input, the internal time-on counter of the respective group is reset to 0 operating hours.
Maintenance signal group A-C	Output	The outputs are switched on when the on-time of the respective group has reached the selected threshold value for the maintenance interval.
On time group A-C	Output	At these outputs, the on-time of the respective group is output as operating hours in hours:minutes:seconds.
Off time group A-C	Output	At these outputs, the off-time of the respective group is output as operating hours in hours:minutes:seconds. This is reset after a server restart because the component cannot know how long the service was off or what the real off-time is.

Properties

Name		function
Number of Group	2	Here the number of groups, 2 or 3, is selected.
maintenance interval [h]	5000	Here, the threshold for the on-time of the maintenance interval is set. The threshold value is the same for all groups.
Time On/Off update interval [s]	60	The on or off times of the groups are output at this distance on the corresponding outputs.
Interval "All on"		If this parameter is set, the signal at the input "Turn on all groups" is used inverted. The function is then active with an off signal at the input.
Interval "All Off"		If this parameter is set, the signal at the input "switch off all groups" is used inverted. The function is then active with an off signal at the input.
