Table 3: TRI/TRX data
column
position
Designation Purpose and particularities
1 Header bus header for OBD/UDS (hexadecimal) 0 = no protocol
or specific Can Bus Identifier for protocol
2 Can ID Can Bus Identifier (hexadecimal)
when using OBD/UDS/TP2.0: Address for querying the device
3 Format 0 -> Big endian; 1-> little endian; 2 -> VEMS (serial);
4 -> IEEE-754 float (Lenght=4)
4 Start byte First byte in Can Bus packet (0-7)
5 Length Length in bytes - 1, 2 or 4
for AINs: Attenuation strength 0-249 (0 = no attenuation)
6 unsigned if the value is negative, please do not tick the box
7 shift Bit moves the bit within the value to the right by position X
8 CAN Mask Masks the value before shift (0 -> no mask applied)
9 Decimal places Number of decimal places
10 Sensor Name Sensor name (maximum 15 characters, no special characters)
11 initCalc Can Bus value gets multiplied by this number
Result= ((Can Bus value & MASK)>>SHIFT) *IINITOFFSET
12 initOffset after multiplication this value is added
13 Mapper type OFF, MAP (linear analog sensors); NTC (3 constants and pull-up
resistor (Steinhart-Hart))
14 MapperInfo1 Varies by mapper type
15 MapperInfo2 Varies by mapper type
16 MapperInfo3 Varies by mapper type
17 MapperInfo4 Varies by mapper type
18 AIN active Internal analog sensor only; enables input pin polling
19 Min Lower warning value
20 Max Upper warning value
21 RefSensor reference sensor: only if the RefValue for this sensor is exceeded,
warning is active
22 RefValue Reference value for enabling the alert
24 Pop Popup active when exceeding or falling below the warning value
6.1 Name encoding of TRI/TRX files
Our TRI/TRX files always have the following name:
𝑋 − 𝐴𝐵𝐶 − 𝑋 . 𝑇𝑅𝐼
or
𝑋 − 𝐴𝐵𝐶 − 𝑋 . 𝑇𝑅𝑋
The first letter identifies the protocol used. More information on the protocols can be found in
Chapter 6.2
The letters two to four identify the engine code letter or ECU. The engine code DAZA becomes X-
DAZ-X or a Syvecs ECU becomes X-SYV-X here. For freely programmable ECUs, however, the names
can also be longer than three digits (e.g. MaxxECU -> X-Maxx-X). The maximum number of digits
including ending is 15 characters.
The fifth or fifth last letter in the name of the TRI/TRX file indicates the units or languages used to
name the sensors :
•
- G stands for the language German and units metric
