Micro-PWC OPERATOR’S MANUAL
Introduction 1
1.0 Introduction
The Micro-PWC is an operator’s console for use with Micro-DCI instruments. This manual describes the
operations required to use a configured Micro-PWC. It is designed to accomplish the following objectives:
• provide instructions on how to perform operational tasks on the Micro-PWC
• provide suggestions and examples for operator activities
• provide additional information as necessary
1.1 Intended Audience
This manual is intended for use by personnel engaged in operating Micro-DCI equipment.
1.2 Functional Description
Micro-DCI provides the capability to divide process functions among many system components to provide
operating flexibility, system reliability, reduced system costs and ease of implementation. Distribution com-
bined with redundancy also allows system control and operating functions to be divided among system
elements to increase reliability and flexibility, and to reduce risk.
Micro-PWCs can be organized into console groups with a maximum of 10 console-type server nodes in
each group. Many types of data and configuration information are distributed automatically to all server
nodes in the same console group.
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 graphical presentation of
plant process conditions as well as reporting functions. The Micro-PWC and Micro-DCI process control
instruments form the basic building blocks of the Micro-DCI Distributed Control System. The Micro-PWC is
the human/machine interface to this system, providing the Process Operator, Process Engineer, Instru-
ment Engineer and Maintenance personnel with global access to all process and system parameters
required by each to perform their respective tasks.
The 53PW6000 (Micro-PWC) on a Pentium-based Personal Computer hardware platform provides the
user interface in a Windows NT environment. Using interactive process graphics and hierarchical dis-
plays, the Process Operator can monitor and control all analog loops and discrete devices interfaced to the
network, as well as sequential batch operations.
The Micro-PWC provides the Engineer with an interface through which to configure and change Graphic
and Hierarchical Displays, database I/O, Micro-DCI process control functions and sequences, Log (report)
formats, and security features (including access levels for operating personnel). Most changes are immedi-
ate, on-line and distributed to all Micro-PWCs within 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.
1.2.1 User Interface
The Micro-PWC provides the Process Operator, Engineer, and Maintenance Technician with a window-
based interface to both the process and the Micro-PWC itself. The user interface is described in detail in
Section 2 .
