DALI Registers

DALI_COMMAND_REGISTER (40253)

The register contains an integer value representing actual configuration of particular functions assigned to the DALI interfaces. The register contains statuses and commands of both DALI interfaces in order to allow for the use of the only one register in the BMS to control the DALI network.

DALI1_ON_OFF_STATE (40253) Bit 0

The bit state shows the actual state of the DALI 1 interface.

If the bit is active (bit 0=1), the DALI 1 interface is ON, which means that the ballasts are set in a scene. Changing the bit state to 0 (inactive) sends the DALI1_BROADCAST_OFF command into the network.

If the bit is inactive (bit 0 =0), the DALI 1 interface is OFF, which means that the ballast are OFF. Changing the bit state to 1 (active) sends the DALI1_BROADCAST_LAST_SCENE command into the network.

The bit allows to read actual state of the ballasts connected to the DALI 1 interface and to send BROADCAST_OFF and BROADCAST_LAST_SCENE commands to the DALI 1 network. This functionality allows for using the only one single bit to read status and write commands, which makes it easier to create a visualization and limit the number of variables.

DALI1_BROADCAST_LAST_SCENE (40253) Bit 1

The raising edge of the bit sends the Last Scene Command to DALI 1 Interface to all the ballasts connected to the interface. The command is useful if there is a need of light up all ballasts connected to the DALI 1 interface remotely from BMS also without a discovery procedure (all ballasts connected to the DALI 1 interface react for Broadcast Last Scene even if short addresses of the ballasts are unknown). The command allows for recalling the last scene by activating only the one single bit, which can be really useful in case of creating a visualization.

DALI1_BROADCAST_OFF (40253) Bit 2

The raising edge of the bit sends the OFF command to the DALI 1 interface to all ballasts connected to the interface. The command is useful if there is a need of turn off all ballasts connected to the  DALI 1 interface remotely from BMS also without a discovery procedure (all ballasts connected to the DALI 1 interface react for Broadcast OFF even if short addresses of the ballasts are unknown). The command allows for recalling the last scene by activating only one bit, which can be really useful in case of creating a visualization.

DI1_COMMAND (40253) Bit 3

The bit overrides a signal from the digital input 1. The command simulates the physical signal on I1 from BMS.

If the bit is active (bit 3=1), the digital input 1 is overridden and considered active (closed circuit). If the bit is inactive (bit 3=0), the digital input 1 is overridden and considered inactive (open circuit).

DALI2_ON_OFF_STATE (40253) Bit 4

The bit state shows the actual state of the DALI 2 interface.

If the bit is active (bit 0=1), the DALI 2 interface is ON, which means that the ballasts are set in a scene. Changing the bit state to 0 (inactive) sends the DALI2_BROADCAST_OFF command into the network.

If the bit is inactive (bit 0=0), the DALI 2 interface is off, which means that the ballast are off. Changing the bit state to 1(active) sends the DALI2_BROADCAST_LAST_SCENE command into the network.

The bit allows for reading actual state of ballasts connected to DALI 2 and sending BROADCAST_OFF and BROADCAST_LAST_SCENE commands to the DALI 2 network. This functionality allows for using only one bit to read status and write commands, which makes it easier to create a visualization and limit the number of variables.

DALI2_BROADCAST_LAST_SCENE (40253) Bit 5

The raising edge of the bit sends the Last Scene Command to the DALI 2 interface to all ballasts connected to the interface. The command is useful if there is a need of light up all ballasts connected to the DALI 2 interface remotely from BMS also without
a discovery procedure (all ballasts connected to the DALI 2 interface react to Broadcast Last Scene even if short addresses of the ballasts are unknown). The command allows for recalling the last scene by activating only one bit, which can be really useful in case of creating a visualization.

DALI2_BROADCAST_OFF (40253) Bit 6

The raising edge of the bit sends the OFF command to the DALI 2 interface to all ballasts connected to the interface. The command is useful if there is a need of turn off all ballasts connected to the DALI 2 interface remotely from BMS also without a discovery procedure (all ballasts connected to the DALI 2 interface react to Broadcast OFF even if short addresses of the ballasts are unknown). The command allows to recall the last scene by activating only one bit, which can be really useful in case of creating a visualization.

DI2_COMMAND (40253) Bit 7

The bit overrides a signal from the digital input 2. The command is dedicated to simulate the physical signal on I2 from BMS.

If the bit is active (bit 7=1), the digital input 2 is overridden and considered as active (closed circuit). If the bit is inactive (bit 7=0), the digital input 2 is overridden and considered inactive (open circuit).

DALI1_RECEIVED_FRAMES_COUNTER (30229)

The 32-bit register with the number of valid DALI receives messages by the device from the ballasts since the last powered up through the DALI 1 interface.

DALI1_BROADCAST_LAST_SCENE (40254) Bit 1

The raising edge of the bit sends the Last Scene Command to the DALI 1 interface to all ballasts connected to the interface. The command is useful if there is a need of light up all ballasts connected to the DALI 1 interface remotely from BMS also without a discovery procedure (all ballasts connected to the DALI 1 interface react to Broadcast Last Scene even if short addresses of the ballasts are unknown).

The command allows for recalling the last scene by activating only one bit, which can be really useful in case of creating a visualization.

SI1_BLOCKING (40254) Bit 3

The bit allows to activating / deactivating a motion sensor / presence detector operating with connection to the special input 1.

If the bit is active (bit 3=1), the motion sensor / presence detector connected to the special input  1 is active and its signal has an impact on the control algorithm.

If the bit is inactive (bit 3=0), the motion sensor / presence detector connected to the special input 1 is inactive and its signal does not have impact on the control algorithm. The default value is 1 (active).

DI1_DIMMING_OFF (40254) Bit 4

The bit allows for activating / deactivating a dimming function assigned with the digital input 1.

If the bit is active (bit 4=1), the dimming function for the switch(es) connected to the digital input 1 is disabled.

If the bit is inactive (bit 4=0), the dimming function for the switch(es) connected to the digital input 1 is enabled.

The switch holds the function to switch on or off the lighting only the dimming function is disabled.

DALI1_DIMMING_STATE (40266)

The register contains an integer value representing the dimming state of ballasts connected to the DALI1 interface.

The command is useful if there is a need of dim all ballasts to the specific level remotely from BMS also without a discovery procedure (all ballasts connected to the DALI 1 interface react to dimming state even if the short addresses of the ballasts are unknown).

The minimum value of 0 means that all the ballasts are off, the maximum value of 254 means the maximum possible brightness level of the ballasts. By default, the register value is 0.

DALI1_FADE_RATE (40462)

The register contains an integer value representing the fade value in steps per seconds that are performed in response to fade command executed by switches controlling the ballasts connected to the DALI 1 interface.

The fade rate allows to change the precision of brightness level setting from switches. The function can be useful in the areas where the ballasts need to be dimmed, for example, in open spaces where the brightness level need to be set individually. The user can adjust most convenient fade rate to requirements and find the most optimal compromise between the time and the precision of changing the brightness level.

Appropriate number represents the time in seconds, which is needed to fade up / down the ballasts between the minimal brightness value and the maximal brightness value.

The fade rate is expressed in steps per second. The table below shows the register values assigned to the number of steps per seconds, which is valid during the dimming procedure. The minimum and maximum values create a range which sets the number of possible steps.

For example:

Minimum ballast value = 0

Maximum ballast value = 254

There are 254 possible steps.

The Fade Rate register value 1 (358 steps per second) means that dimming / lighting up procedure takes less than one second.

The Fade Rate register value 15 (2.8 steps per second) means that dimming / lighting up procedure takes about 254 / 2.8 = 90.5 seconds (Fade Time).
