Parameters for status functions

This parameter provides a global definition of the delay time for automatic transmission of the status functions after a device reset for all groups and single devices of the DALI system.

The setting "0" deactivates the delay completely. In this case, all status telegrams are transmitted to the KNX without delay.

After central commands or after the bus/mains voltage returns, a KNX line is generally heavily loaded by telegrams because numerous bus devices transmit the state of their communication objects as status. This effect occurs particularly when using visualisations. Collective feedback of the gateway can be used to keep the telegram load low during initialisation.

The collective feedback summarises the switching states of the groups and single devices in bit-orientated form. Up to four separate 4-byte communication objects are available for this, depending on the set addressing type. Each of these objects can visualise the switching state of up to 16 groups or devices.

At this point, you can define when the gateway is to update the status of the collective feedback. The object value most recently updated by the gateway is then actively reported to the KNX, provided the "Transmit" flag is set on the communication objects.

After each update of the "Switching"/"Central switching" object: The gateway updates the feedback values in the collective feedback as soon as the input objects "Switching - Default" or "Central Function... - Switching" for groups or single devices are updated. A new telegram is also then actively transmitted to the KNX each time. The telegram value does not necessarily have to change. Hence, corresponding collective feedbacks are also generated, e.g. in the event of cyclical telegrams to the input objects.

Only if the feedback value changes: The gateway updates the feedback values in the collective feedback objects only if the telegram values of the inputs also change. The feedback remains unchanged if telegram values do not change (e. g. in the event of cyclical telegrams to the input objects with the same telegram value). Consequently, no telegram with the same content is then issued repeatedly.

The states of the collective feedback are transmitted to the KNX after the bus or mains voltage returns or after an ETS programming operation. In these cases, the feedback telegram can be time-delayed, with the delay set globally for all groups and single devices together.

The objects of the collective feedback can also transmit their value cyclically in addition to transmission when updating.

The collective feedback can also be transmitted cyclically, in addition to transmission in the event of an update. If cyclical transmission is activated, the cycle time can be configured here.

The gateway can monitor its supply voltage at the mains voltage connection. If there is a failure, the gateway is able to transmit a status telegram to the KNX before stopping operation, provided the bus voltage is uninterrupted. Optionally, the switch-on of the mains voltage supply can also be fed back.

This parameter defines when the status for the supply voltage is transmitted by the gateway.

Only on voltage failure: As soon as a mains power failure is detected at the gateway, the device immediately transmits a status telegram. It stops operation just a few seconds later.

On voltage failure and return: As soon as a mains power failure is detected at the gateway, the device immediately transmits a status telegram. It stops operation just a few seconds later. The gateway initialises itself when the mains power supply is switched on. Then it transmits a status telegram once and signals that the mains voltage is switched on.

This parameter is available only if mains voltage monitoring is enabled.

The gateway detects short-circuits on the DALI cable, as may occur in the case of an installation error or an overload due to excessive power consumption of the connected DALI operating devices and DALI sensors.
As soon as a short-circuit is identified on the DALI line with the mains power supply switched on, the gateway transmits a status to the KNX when the status function for DALI short-circuits is enabled here.

During operation of the gateway, it is possible for the telegram load of the DALI system concerned to increase, especially if a number of control functions of the groups and single devices are running simultaneously. The gateway signals DALI busy if the load reaches or exceeds a defined limit so that trouble-free operation of the DALI system is no longer guaranteed. This signalling takes place if the parameter is activated on the 7-segment display of the device ("db" indication) and optionally also to the KNX by means of a 1-bit communication object "Status - DALI busy".

Acknowledgement prevents the simple confirmation of a DALI busy by the object "Status - DALI busy".

Checkbox activated: DALI system identified, it indicates "db" on the 7-segment display on the front of the device. In addition, the 1-bit object "Status - DALI busy" is available, which signals the load also by means of an ON telegram. To confirm this status message, an ON telegram must be received by means of the 1-bit object "Acknowledgement - DALI busy". Only after acknowledgement has taken place does the gateway reset the status in the object "Status - DALI busy" with an OFF telegram. If the load in the DALI system remains high after acknowledgement, the gateway sets the status again so that another acknowledgement is required.

Checkbox deactivated: The "DALI busy" status is activated. As soon as the gateway identifies a busy DALI system, it indicates "db" on the 7-segment display on the front of the device. In addition, the 1-bit object "Status - DALI busy" is available, which signals the load also by means of an ON telegram. Confirmation of this status message is not required. The gateway automatically revokes the status with an OFF telegram as soon as the load of the DALI system returns to normal.

This parameter is available only if DALI busy is enabled.

The gateway allows the error status of DALI operating devices to be indicated. The general status "Error in DALI system" can be used if individual evaluation and indication of the error status of individual electronic ballasts or groups and single devices is not required or is to be supplemented with a status function, independent of the electronic ballast. This status function has the 1-bit communication object "Status - Error - DALI system", which allows a general error to be indicated in the DALI installation. The gateway sets the object value to "ON" as soon as it detects an error in a previously commissioned DALI operating device. Here, it is irrelevant which error was identified by the gateway (lamp error, electronic ballast error, converter error). The gateway does not reset the object value to "OFF" until all the previously identified errors have been eliminated.

Optionally, the error status in the DALI system can be transmitted repeatedly, if, after a previously identified DALI error, further errors are detected on the same or other operating devices. This parameter defines the behaviour of the general error status in the event of new errors.

This parameter is available only if the error status in the DALI system is enabled.

The gateway allows the signalling of an individual error status of DALI operating devices in up to two different data formats. To use this status function, this parameter must be activated.

This parameter determines whether only a 1-byte object (according to KNX DPT 238.600), a 2-byte object (according to KNX DPT 237.600) or a combination of both objects is used.

This parameter is available only with the error status enabled per DALI operating device.

Optionally, this parameter can be used to activate a delay of the error status per DALI operating device after the initialisation of the gateway (ETS programming operation, mains voltage return). The delay time is configured globally on the parameter page "DALI System... -> General".

This parameter is available only with the error status enabled per DALI operating device.

In addition to the global error status in the DALI system or the error status of the DALI operating devices, the gateway can generate an individual error status per projected group or single device.

Optionally, the error status per DALI group / single device can be transmitted repeatedly if further errors are detected in the same group or single device after a previously identified DALI error. This parameter defines the behaviour of the error status per DALI group / single device in the event of new errors.

This parameter is available only with enabled error status per DALI group / single device.
