DALI Registers Available Only After DALI X Network Commissioning

Some of the device functions and registers assigned with DALI network(s), DALI1 or DALI2, are available only after the DALI X network commissioning process.

All Modbus registers, which are available only after commissioning, are described below.

DALI1_BALLAST_ACTUAL_LEVEL (30161- 30176)

The register contains information about actual brightness level from minimum 0 to maximum 254 of the particular ballast. Each register is assigned to the ballast number according to the following table:

DALI2_BALLAST_ACTUAL_LEVEL (30177 - 30192)

The register contains information about actual brightness level from minimum 0 to maximum 254 of the particular ballast connected to the DALI 2 interface. Each register is assigned to the ballast number according to the following table:

DALI1_BLINK (40262)

Each bit of the register activates blinking of the particular ballast assigned to the bit. It is possible to start blinking of several ballasts at the same time. The function is useful during the commissioning of the DALI network, including ballasts addressing (discover process) to localize the specific lamp in order to appropriate visualization in BMS. To do so, appropriate bits have to be activated according to the table below:

To stop blinking, the ballasts the particular bits have to be set to 0. The default value is 0.

DALI2_BLINK (40263)

Each bit of the register activates blinking of the particular ballast assigned to the bit. It is possible to start blinking of several ballasts in the same time. The function is useful during the DALI network commissioning including ballasts addressing (discover process) to localize the specific lamp in order to appropriate visualization in BMS. To do so, appropriate bits have to be activated according to the table below:

To stop blinking the ballasts the particular bits have to be set to 0. The default value is 0.

DALI1_BALLAST_SETPOINT (40270-40285)

Registers contain integer values, which represent the setpoint values sent to the particular ballasts connected to the DALI 1 interface in accordance with the table below.

If there is a need to set particular ballast brightness level in the DALI 1 network remotely from BMS, it is possible to use the DALI1_BALLASTX_SETPOINT registers.

If the ballasts brightness levels are set individually for each ballast by BALLAST_SETPOINT registers, there could be a need to hold this particular scene without a possibility to change the brightness level by switches. To deactivate the dimming function for switches, a register bit DI1_DIMMING_OFF has to be activated.

The function can be useful especially in the open spaces, where the brightness level needs to be set individually inside the single DALI network.

The minimum value 0 means that the ballasts send OFF command to the lamps, the maximum value 254 means the maximum possible brightness level of the ballast. By default, the register value is 0.

DALI2_BALLAST_SETPOINT (40286-40301)

The register contain integer values representing the setpoint values sent to the particular ballasts connected to the DALI 2 interface in accordance with the table below.

If there is a need to set particular ballast brightness level inside the DALI 2 network remotely from BMS, it is possible to do so using DALI2_BALLASTX_SETPOINT registers.

If the ballasts brightness levels are set individually for each ballast by BALLAST_SETPOINT registers, there could be a need to hold this particular scene without a possibility to change the brightness level by switches. To deactivate a dimming function for switches, the DI2_DIMMING_OFF register bit has to be activated.

The function can be useful especially in the open spaces, where the brightness level needs to be set individually in the single DALI network.

The minimum. value 0 means that the ballast lights with the minimum brightness, the maximum value 254 means the maximum possible brightness level of the ballast. By default, the register value is 0.

DALI1_BALLAST_MIN (40334-40349)

The register contain integer values, which represent the minimal brightness levels for the particular ballasts connected to the DALI 1 interface, in accordance with the table below.

The minimum value 0 means that the ballast minimum value is the same as in case of the OFF command (ballast is off), the maximum value 253 means that ballast cannot be dimmed in practice (the ballast setpoint value 254 means maximum possible factory brightness level of the ballast). The minimum value determines a low limit of dimming the ballast, both by dimming procedure initiated by monostable switch (writing down a lower value than it is stored in the register sets the ballast brightness level on the value of the register). By default, all registers values are 0.

DALI2_BALLAST_MIN (40350-40365)

The registers contain integer values, which represent the minimum brightness levels for the particular ballasts connected to the DALI 2 interface in accordance to the table below.

The minimum value 0 means that the ballast minimum value is the same as in case of the OFF command (ballast is off), the maximum value 253 means that ballast cannot be dimmed in practice (the ballast setpoint value 254 means the maximum possible factory brightness level of the ballast). The minimum value determines a low limit of dimming the ballast, both by dimming procedure initiated by monostable switch (writing down a lower value than it is stored in the register sets the ballast brightness level on the value of the register). By default, all registers values are 0.

DALI1_BALLAST_MAX (40398-40413)

Registers contain integer values, which represent the maximum brightness levels for the particular ballasts connected to the DALI 1 interface according to the table below.

The maximum value 1 means that ballast cannot be lighted up in practice (the ballast setpoint value 0 means that the ballast is off). The maximum value determines a high limit of lighting up the ballast, both by lighting up procedure initiated by monostable switch (writing down a higher value than it is stored in the register sets the ballast brightness level on the value of the register). By default, all registers values are 254.

DALI2_BALLAST_MAX (40414-40429)

The registers contain integer values, which represent the maximum brightness levels for the particular ballasts connected to the DALI 2 interface according to the table below.

The maximum value 1 means that ballast cannot be lighted up in practice (the ballast setpoint value 0 means that the ballast is off). The maximum value determines a high limit of lighting up the ballast, both by lighting up procedure initiated by monostable switch (writing down a higher value than it is stored in the register sets the ballast brightness level on the value of the register). By default, all registers values are 254.

DALI1_NUMBER_OF_BALLASTS (30258)

The register contains an integer value representing the number of ballasts connected to the DALI 1 interface with the short addresses given during the one of the discovery process (NEW_INITIALIZATION, REPLACE_BALLAST, ADD_NEW_BALLAST).

DALI2_NUMBER_OF_BALLASTS (30259)

The register contains an integer value representing the number of ballasts connected to the DALI 2 interface with the short addresses given during the one of the discovery process (NEW_INITIALIZATION, REPLACE_BALLAST, ADD_NEW_BALLAST).

DALI2_FAULT_STATUS_REGISTER (30158)

The register contains an integer value representing common fault status from all ballasts connected to the DALI 2 interface. Each bit of the register represents a fault state of the particular ballast in accordance with the following table:
