Section 7 I/O Displays - ABB 800xA Operation

I/O Displays Overview
I/O displays contain information that allow you to identify detectable fault
conditions, monitor general status and performance, change process outputs directly
for testing, and control the status of redundancy. The I/O displays include:
•
•
•
•
•
Entries identifying an operator action on the I/O displays are relayed to the
appropriate logging device. Color coding of data shown on the displays is like the
diagnostic displays. Hardware factors to consider are:

S800.
S100.
PROFIBUS.
TRIO.
Direct I/O.
No more than 30 TRIO blocks can be attached to a Field Bus Controller.
A SC Controller I/O Module has either all TRIO or all Direct I/O.
A SC Controller can have two Field Buses at most. Each can be either non-
redundant or redundant.
All SC Controllers backed up by one specific backup controller must have the
same type of I/O: either TRIO or Direct I/O.
An Advant Controller 460 can have a mixture of TRIO and local S100 I/O,
with a maximum of four non-redundant or two redundant Field Buses.
An Advant Controller 410 can have a mixture of TRIO and local S100 I/O,
with a maximum of two non-redundant or one redundant Field Bus(es).
