Plant I/O Subsystem
Plant I/O
Subsystem:
Overview
The iBox Plant I/O Subsystem collects, processes, and stores data related to physical
inputs and outputs. Once it is stored in the system database, I/O point data can be
accessed by other applications.
Plant I/O
Subsystem:
Functions
The Plant I/O Subsystem is responsible for scanning of iBox physical I/O points. For
input type points (digital and accumulator), the data of each scan is compared to
previous known data. Changes are recorded in the system database, then reported to
other applications, as needed.
The Plant I/O Subsystem:
•
Scans and processes up to 8 digital inputs
•
Controls up to two digital outputs and two master trip/close relays.
Requests for digital outputs are accepted and processed as soon as they arrive.
Fixed Number
of Points
The Plant I/O DCA maintains a fixed number of points in the System Point
Database. The actual number of points is determined by the version of the P097 Plant
I/O Subsystem that has been installed on your iBox.
The hardware options available in the iBox (and the user’s software configuration)
determine if specific system features and data points are available or disabled.
