Parameters for operating hours counter

The operating hours counter can be enabled here. The operating hours counter determines the switch-on time of a group or single device. A group or single device is switched on for the operating hours counter if the lamp is lit.

If the operating hours counter is not enabled, no operating hours will be counted for the group concerned or the single device. Once the operating hours counter is enabled, however, the operating hours will be determined and added up by the ETS immediately after commissioning the gateway.

If the operating hours counter is subsequently disabled again in the parameters and the gateway is programmed with this disabling function, all operating hours previously counted will be deleted. When enabled again, the meter reading of the operating hours counter is always set to "0".

The operating hours counter can either be configured as a second counter or alternatively as an hour counter.

Seconds: The gateway adds the determined switch-on time for a switched-on group or single device to the second. The totalled operating seconds are added in a 4-byte counter and stored permanently in the device. The current meter reading can be transmitted cyclically to the KNX by the "Operating hours counter - Counter reading - Status" communication object or when there is a change in an interval value in accordance with DPT 13.100.

Hours: The gateway adds up the determined switch-on time for a switched-on group or single device to full operating hours to the minute. The totalled operating hours are added in a 2-byte counter and stored permanently in the device. The current meter reading can be transmitted cyclically to the KNX by the "Operating hours counter - Counter reading - Status" communication object or when there is a change in an interval value in accordance with DPT 7.007.

The operating hours counter can be configured as an up-counter or down-counter. The setting here influences the visibility of the other parameters and objects of the operating hours counter.

If the up-counter is used, a signal value can optionally be predefined.

This parameter is visible only in "forwards" counting direction.

This parameter defines whether the signal value can be set via a separate parameter or adapted individually by a communication object from the bus.

This parameter is visible only in "forwards" counting direction.

The signal value of the up-counter is set here. Once the signal value is reached, an "ON" telegram is transmitted via the object "Operating hours counter - Counter elapsed - Status". The meter itself continues until the maximum meter reading is reached and then stops.

*: With second counter
**: With hours counter

This parameter is visible only if the parameter "Specify signal value" is activated and the "Preset value" parameter set to "via parameter".

If the down-counter is used, a start value can optionally be predefined.

This parameter is visible only in "backwards" counting direction.

This parameter defines whether the start value can be set via a separate parameter or adapted individually by a communication object from the bus.

This parameter is visible only in "backwards" counting direction.

The start value of the down-counter is set here.

*: With second counter
**: With hours counter

This parameter is visible only if the parameter "Specify start value" is activated and the "Preset value " parameter set to "via parameter".

The current value of the operating hours counter is continuously tracked in the communication object "Operating hours counter – Meter reading - Status". The content of the object is transmitted to the KNX when there is a change by the set count interval or cyclically active.

Cyclical: The counter value is transmitted cyclically. The cycle time is defined via the parameter of the same name.

After change by interval value: The counter reading is transmitted to the KNX as soon as it is changed by the specified counting interval.

This parameter defines the cycle time for the cyclical transmission. Setting the cycle time hours, minutes and seconds.

This parameter is available only with "Transmission behaviour = cyclical".

The interval of the counter value is set here for automatic transmission. The current meter reading is transmitted to the KNX after the interval configured here.

*: With second counter
**: With hours counter

This parameter is available only with "Transmission behaviour = on change by interval value".
