3.2 Factors for Planning
When you plan an industrial communications strategy that will
integrate various control systems and computer products, you’ll need to
consider the kinds of applications you will implement, their information
requirements, and their control devices. Your planning should be at
three levels: (1) Network Applications; (2) Information Requirements;
and (3) Transaction Requirements. Factors to consider are listed below.
3.2.1 Network Applications
Consider the types of applications you will require for your network:
Process Data Acquisition Local and Remote Programming
Supervisory Control Program Archiving, Upload, and Download
User Interfaces Database Generation for Management Re-
ports
Statistical Process Control Connectivity to Other Types of Networks
Statistical Quality Control
3.2.2 Information Requirements
Consider the kinds of information that must be handled in each
application and between applications:
Process data between interactive nodes Supervisory control and information for user
interfaces
Downloading of recipes and control pro-
grams
Data conversion to computer databases
Production and quality statistics and re-
ports
Process device diagnostics and maintenance
reports
Consider the quantities of each type of information and their
throughput requirements.
How much data must be transferred between devices per unit of time
