If an event burst exceeds the capacity of a buffer, the “lost events” are marked in the data base
file and sent to the operator station with time marked “uncertain” when the load decreases.
These events will not be missing in the event and alarm lists if MasterBus 300 is used.
The maximum steady state rate is 2 events/sec.
Momentary event bursts with higher frequency are handled
as described above.

• Events handled within a controller utilizing S100 I/O or
S800 I/O with SOE functionality <2 ms
• Events handled within a controller utilizing S400 I/O 10-100 ms
(The event is time tagged when the signal arrives at the controller.
Time error depends on scanning selected.)
• Events handled within a subordinated autonomous
controller (for example Advant Controller 110) <1 ms
(Events locally time tagged.)
• Events handled within separate controllers
Advant Controller 450, Advant Controller 410,
Advant Controller 110 (not S400 I/O)
– With external time synch.
1
<4 ms
– No external time synch. <5 ms
• For S800 I/O without SOE functionality, the relative time error between events (DI
signals) in one controller can be evaluated from the expression:
Maximum relative time error = a + b + c
a = scan cycle time of the Fieldbus Communication Interface 5 - 100 ms, not configurable
b = Cycle time of Advant Fieldbus 100 (set by the user, terminal INSCANT)
c = scan cycle time of the process data communication in Advant Controller 450
(set by the user, terminal SCANT).
