|BECKHOFF KL6811: Configuration software KS2000|
The intelligence in the DALI system is not 100% centralised.
This means that a large number of settings and light values are
stored in the form of variables in the ballasts.
Click on Variables. A dialog mask in which you can inspect and edit the variables for the selected DALI device appears.
This variable contains the power currently applying to the lamp.
This variable specifies the lamp power that the DALI device is to adopt after the power supply has been switched on, if the DALI bus is already under power and is idle.
This variable specifies the lamp power that the DALI device is to adopt in the event of a system error.
You specify the minimum lamp power that the DALI device is to adopt here, so that the illuminance does not fall below a level that you want. The MIN value cannot be less than the smallest physically possible value specified by the manufacturer of the DALI device.
You specify the maximum lamp power that the DALI device is to adopt here, so that the illuminance does not exceed a level that you want.
Enter here the speed in steps per second (steps/s) with which the DALI device response to commands to become brighter (DALI command 1dec) or darker (DALI command 2dec) over a period of 200 ms. The absolute fade rate is not entered directly, but it is calculated according to the following formula:
|T = absolute fade rate|
|n = value that is stored in the Fade rate variable|
The following values result:
|n||absolute fade rate|
Enter here the time in seconds that the DALI device is to take
to change the brightness when, for instance, changing a scene, or
direct DALI commands for lamp power. This time is independent
of the size of the change, so that all the lamps complete their
change over the same period. In the case of a lamp that is switched
off, the pre-heating and ignition time is not included in the fade
The absolute fade time is not entered directly, but it is calculated according to the following formula:
|T = absolute fade time|
|n = value that is stored in the Fade time variable|
The following values result:
|n||absolute fade time|
|0||< 0.707 s|
This variable contains the DALI device's short address. A valid short address lies in the range between 0dec and 63dec. If 255dec is written into the variable, the short address is deleted.
This variable can only be read. It contains the DALI device's status byte. The bits in the status byte have the following significance:
|7||Power supply fault||0bin||No|
|6||Missing short address||0bin||No|
|4||Fading done||0bin||Fading has been completed|
|1bin||Fading in progress|
|3||Limit value error||0bin||The most recently requested lamp power value was between the MIN and MAX values, or was OFF.|
|0||Status of the DALI device||0bin||OK|
Displays the DALI device's version number. This variable is entered by the device manufacturer, and can only be read!
Indicates the lowest physically possible lamp power that the DALI device can adopt. This variable is entered by the device manufacturer, and can only be read!
