CANAPE中加载DBC后，如何在脚本中获取到DBC内的信号量

Question:

How to access CAN signals when the signal name exists more than one time?

Answer:

In the DBC file a CAN signal exists more than one time with different CAN message IDs. To access this signal via a script/function you have to use the message and the signal name.

Syntax for working with CAN devices:

value = .'$$'.mbuffer[0];

Example:

In this example, the Device ID is "Vin". Both CAN messages "VIN1" and "VIN3" include the CAN signal "Kanal1".

var value, value2;
value = Vin.'$VIN1$Kanal1'.mbuffer[0];
value2 = Vin.'$VIN3$Kanal1'.mbuffer[0];

Syntax for working with MDF files:

[[.].]].

Example:

In this example, the name of the file is "FILE1". The message name is "VIN1", and the channel number is "1".

value = FILE1.Kanal1;
value = FILE1.VIN1.Kanal1;
value = FILE1.1.VIN1.Kanal1;

Please note, that Channel Number and Message Name are additional and optional.
