9.1.3 Label Lists
For all protocols using ID or address identification, it is possible to create label lists
containing addresses or IDs, a symbolic name for each node (symbolic label), and
some protocol-specific information.
You can load label lists, and activate its usage for decoding. As a result, an additional
"Label" column appears in the "Decode results" table, containing the symbolic label.
The frame captions of the decoded signal show the symbolic label instead of the ID or
address values. Hence it is easy to identify the messages of the different bus nodes.
You can also use the label list to trigger on an identifier or address. Instead of entering
the value, you select the name, which is defined in the label list.
Available file formats are PTT, CSV, and DBC (CAN only).
Label lists are protocol-specific. Their contents are described in the corresponding pro-
tocol chapters:
●
Chapter 9.2.4, "I²C Label List", on page 185
●
Chapter 9.5.4, "CAN Label List", on page 213
●
Chapter 9.6.4, "LIN Label List", on page 223
●
Chapter 9.7.4, "SENT Label List", on page 237
9.1.3.1 Using Label Lists
To load a label list and display the labels:
1. Save the label list file on a USB flash drive, or on the microSD card.
2. Press and hold the [BUS] key until the menu opens.
3. Configure the protocol.
4. In the "Bus" menu, tap "Load Label List".
5. Navigate to the label list file, select it, and tap "Select".
6. To read the label list, tap "Show Label List".
7. To use the labels in the display of the decoded data, tap "Display Labels".
To trigger on an identifier or address using the label:
Prerequisites: The bus is configured, decoding is enabled, and a decoded signal is visi-
ble.
1. Open the "Trigger" menu.
2. Set the following trigger settings:
● "Trigger Mode" = "Normal"
● "Trigger Type" = "Bus"
●
"<Protocol> T
rigger" = "Identifier", or "Identifier + Data", or "Address", or
"Address and Data".
