6.6 Time Synchronization

6.7 Time Tagging of Events (Alarms)

6-8
Between nodes on the same MasterBus 300/300E control network, the accuracy
is better than 3 ms.
External minute pulse can be connected to Advant Controller 450, giving an accuracy better
than 2 ms. between the external clock and the internal clock in Advant Controller 450.
S100 I/O or S800 I/O
Time tagging of two DI signals on S100 I/O boards or two DI signals on S800 I/O modules.
The relative time error between events handled within one controller is max. 2 ms.
The relative time error between events handled within separate controllers are max. 4 ms,
typically 3 ms.
S100 I/O and S800 I/O
Time tagging of one DI signal on S100 I/O board and one DI signal on S800 I/O module.
The relative time error between events handled within one controller is max. 3 ms.
The relative time error between events handled within separate controllers are max. 5 ms,
typically 4 ms.
S800 I/O
Time tagging in the controller system software.
For S800 I/O the relative time error between events (DI signals) in one controller can be
evaluated from the expression: Relative time error = a + b + c
a = scan cycle time of the FCI unit (5 - 100 ms, due to number of modules and types)
b = transmission cycle time of Advant Fieldbus 100 (set by the user)
c = scan cycle time of the PDC in Advant Controller 450 (set by the user)
Advant Controller 55/70/110/160
Time tagging in a controller Advant Controller 55/70/110/160. It is possible to receive events
from Advant Controller 70/110/160 using Advant Fieldbus 100, or from Advant Controller
55/110/160 using RCOM/RCOM+.
