Micro-PWC CONFIGURATION GUIDE
Introduction 1
1.0 Introduction
1.1 Overview
The Micro-PWC is an operator’s console designed for use with Micro-DCI and other compatible equip-
ment. This Configuration Guide describes the operations required to configure the Micro-PWC. It is
designed to accomplish the following objectives:
• Provide instructions on how to perform configuration tasks on the Micro-PWC.
• Provide suggestions and examples for configuration activities.
• Provide additional information as necessary.
1.2 Intended Audience
The Micro-PWC Configuration Guide is intended for use by personnel engaged in the configuration of the
Micro-PWC. The Micro-PWC communicates with the Micro-DCI control instruments. Familiarity with these
instruments is necessary to understand the functions of a Micro-PWC.
1.3 Functional Description
Micro-DCI is a distributed process control and information management system which provides the ability
to divide process functions among many system components to provide operating flexibility, system reli-
ability, reduced system costs, and ease of implementation. Distribution combined with redundancy also
allows system control and operating functions to be divided among system elements to increase reliability
and flexibility and to reduce risk.
Console-type nodes (computers on which the Micro-PWC software is in use) which reside on the same
network can be organized into console groups of up to 10 console-type server nodes each. Many types of
data and configuration information are distributed automatically to (or synchronized between) all server
nodes in the same console group, and can be distributed on demand to other console groups via a utility
known as console group synchronization.
Automation of most processes requires more than control at the unit operations level. The system must
also include an inherent ability to provide process management functions such as scheduling and graphi-
cal presentation of plant process conditions, as well as reporting functions. The Micro-PWC, controllers,
field wiring interface terminal boards, and process control software form the basic building blocks of the
distributed control system. The Micro-PWC is the HSI (human system interface), providing the process
operator, process engineer, instrument engineer and maintenance personnel with global access to all pro-
cess and system parameters required by each to perform their respective tasks.
The Micro-PWC provides the Process Operator with a window to the process. Using interactive process
graphics and hierarchical displays, the Process Operator can monitor and control all analog loops and dig-
ital devices interfaced to the network.
The Micro-PWC provides the Engineer with an interface through which to configure and change Graphic
and Hierarchical displays, database I/O, controller process control functions and sequences, Log (report)
formats, and security features (including Access Levels for operating personnel). Most changes are imme-
diate, on-line, and distributed to all Micro-PWCs in the same console group, requiring no compilation time
before downloading, and therefore no interruption of the process.
The Micro-PWC provides Maintenance Personnel with the capability to globally monitor the operating sta-
tus of any system component on the network, and to diagnose component failures from any Micro-PWC.
