13.7.3 FlexRay label list
Label lists are protocol-specific. A FlexRay label file contains four values for each iden-
tifier:
●
"ID / Addr": number of the slot in which the frame is transmitted
●
"Base cycle" and "Repetition": define the cycle indexes for which the identifier
applies. Base cycle defines the first applied cycle.
There are 64 cycles in a FlexRay communication. The same identifier can be
shared by different devices, and each device uses the identifier at different cycles.
For example:
0x0AB,0,2,Ignition_Info: uses cycles 0,2,4,6,...,62
0x0AB,1,2,GearBoxInfo: uses cycles 1,3,5,7,...,63
●
"Symbolic label": symbolic name of the identifier, specifying the device function.
