Section 1. Introduction
1-1. Overview
This manual describes the configuration and operation of the Ovation Link
Controller module in an Ovation Process Control System.
1-1.1. System Overview
The Ovation Distributed Control System provides modulating control, sequential
control, and data acquisition for a variety of system applications. This system
consists of a configurable mix of functional Input/Output (I/O) modules (described
in “Ovation I/O Reference Manual” (R3-1150)) that communicate on the I/O bus to
the Ovation Controller.
An Ovation I/O module consists of an electronics module and a personality module.
These modules are “plug-in” components with built-in fault tolerance and
diagnostics. They are able, by combining different personality modules with
electronics modules, to operate at a wide range of signals, and perform a multitude
of functions.
The Ovation I/O modules are locked into Base Units (two modules per Base Unit).
These Base Units are housed in the Controller cabinets where they are mounted on
DIN rails and wired to the appropriate field devices (see example of Controller
cabinet in Figure 1-1 and detailed cabinet descriptions in “Ovation Planning and
Installation”(U3-1000).
The modular components consist of the following:
•
Electronics module
•
Personality module
•
Base Units (containing the field terminations)
