2.3 I/O System Support
S100 I/O System
S100 I/O boards are located in I/O subracks which are integrated with Advant Controller 450 in
the same cabinets and connected to the controller subrack via a bus extension cable (max. length
12 m (39 ft.). For increased availability the S100 I/O bus extension can be doubled
(redundancy). S100 I/O subracks can also be distributed via an optical bus extension (max.
length 500 m (155 ft.). For further information about S100 I/O, please refer to the Product
Guide for S100 I/O.
S800 I/O System
The distributed S800 I/O modules communicate with the Advant Controller 450 over
the Advant Fieldbus 100, via the CI522A interface module. The fieldbus communication
between the controller and the modulebus in the S800 I/O station can be doubled (redundancy).
The range of supported S800 I/O modules is shown in
Table 2-1 .
For further information about S800 I/O please refer to the S800 I/O System Product Guide.
2.4 Time Tagging of Events and Alarms
The time tagging of digital input signals can be done in the system software of the controller or
on certain digital input (DI) modules belonging to S100 I/O or S800 I/O. Time tagging on
a DI module results in a high time accuracy. Signals created in AMPL can also be time tagged
but with an accuracy corresponding to the PC program cycle time.
