This article will guide you step-by-step on how to create the luminaires registers map.

In order to have more insight on this matter and determine which registers are crucial for your implementation, please read the reference article: Luminaires registers map (table)

Vertex 3

  1. Download a system report file from Vertex GUI in csv. format. Remember to log in first.

2. Open the downloaded file using MS Excel. You will see information about your system (number of total devices, status information, Luminaires serial number, etc.). For register map calculations we’ll use Dali Port and Short Address data.

3. Filter out DALI-2 devices (eg. buttons).

Vertex stores data on individual luminaires status.

Filtering

Create a table and expand it to fit your data rows.

Click on the DeviceType drop-down list and uncheck the DALI 2 device filter box.

4. Create new columns for the first and last register number of each luminaire.

5. In order to calculate the luminaire’s start register number, use this formula:

Vertex3: (400+DALI short address*50+(DALI port-1)*64*50).

Each luminaire data is stored in 50 registers (first 20 - data, 30 reserved for later use).

 

Vertex 2

  1. Go to http://VERTEX_IP:1880/vertex/devices

  2. Select and copy the contents using ctrl+a and ctrl+c shortcuts.

  3. Convert the data from JSON to CSV (you can use JSON To CSV online converter).

  4. Download the converted file using JSON To Excel button.

5. Open the downloaded file in MS Excel and create a new Excel sheet for clarity.

6. Copy and paste the following columns onto the new sheet:

  • Device UID

  • Device Name

  • ShortAddress

  • DaliPort

  • Vertex UID

7. Create a table and filter out DALI-2 devices as shown here: Filtering

8. Create new columns for the first and last register number of each luminaire.

In order to calculate the luminaire’s start register number, use this formula:

Vertex2: (400+DALI short address*50+(DALI port)*64*50).
