What Is The Best And Worst Case Repeat Ability Of This Configuration?
Answer»
The best case which is 99% the NORMAL case is that the timing is absolute STABLE (5% jitter is possible due to control FUNCTIONS)
In case of a failure (stations are dropping out) the timing can change
1 transmission failure will be CORRECTED within 500/100μs (1,5/12Mbaud)
1 station failure will add a jitter of 700/300μs
A worst case scenario of 33ms by 1.5MBaud or 6.6ms by 12MBaud for one cycle will occur when all stations fail (in this situation the reaction time is meaningless).
After the failure detection the timing is back to the regular cycle time.
