Command Data Format

Signal Name padding
variable 0-3 bytes

Signal Name
The name of the signal for which information will be returned. The name is a null terminated string.

 

Response Data Format

Offset Length Signal Encoding Name padding
1 byte 1 byte variable 0-3 bytes

Offset
The starting bit number of the signal. The bit offset references the data frame as as a single big endian value. That is bit 0 is the most significant bit of the first byte and bit 63 is the least significant bit of the eighth byte.

Length
The length of the signal in bits.

Signal Encoding Name
The name of the signal encoding definition as a null terminated string.

 

note:
The Signal Encoding Name has a variable length. The name is terminated with a null character, making it a standard C string. This enables the use of strcpy() and length() when working with the name.
