Figure 2-26a: Parameter tree node OBD.

 

The Enable OBD signals checkbox is used to turn on the OBD processing (= OBD signals).

 

The Port is used to select either CAN1 or CAN2 for OBD access.

 

Init. Delay: Defines the initial waiting period before protocol detection.

 

Protocol: Defines the used OBD protocol. Auto is used to automatically detect the OBD protocol.

 

Counter Mask: Each OBD signal has an associated counter signal whose name is derived from the name of the OBD signal. A star symbol (*) is a placeholder for the original OBD signal name.

 

Dyn. Signal: Optionally defines the OBD signal which is requested each 2nd time.

 

Compound query: In case of OBD-II, the request is done for two OBD signals at once.

 

Note that there shouldn't be a Code definition referring to OBD access within the device comment. Also note that the request cycle is aligned to the cycle of the calculated signals. Also, for some cars, the refresh rate of the OBD signals may be too fast. In this case, the calculation cycle should be enlarged (to e. g. 30 ms).
