Signaling Examples
Function
The following examples illustrate the frame structure for the three
transmission repetition settings. The HEADER and TERMINATOR
parameters are set to ON (default), and the COLLAPSE CYCLE (CC) is
set to 1 and 2 (messages will be repeated every 2 frames (2l) and
4 frames (22) respectively).
SINGLE Mode Example
Start Cycle: 10
Start Frame: 127
Collapse Cycle: Has no effect
Since HEADER is set to ON, the idle signal is output at Frame 126.
With TERMINATOR set to ON, the asynchronous state signal is
output after the message.
BURST Mode Example
FCC= 1 idle message asynchronous
ICC=2 Iidle)messageIasynchronousI
Start Cycle: 10
Start Frame: 127
Collapse Cycle: 1 (2l) and 2 (22)
Burst: 3
Since HEADER is set to ON, the idle signal is output at Frame 126.
With TERMINATOR set to ON, the asynchronous state signal is
output in the frame where the next message was supposed to
occur (as determined by the collapse cycle).
