The Role of Sensors and Contr ol Technology in CIM
• Managing a program library for queuing and routing messages 265
• Establishing alert procedures
• Monitoring work-cell status
With these functions, Distributed Automation Edition can (1) help
manufacturing engineers select or develop application programs to
control work-cell operations and (2) provide communication capa-
bilities between area- and plant-level systems (Fig. 5.15).
DAE supports several communication protocols to meet the
needs of a variety of enterprises. For example, it supports SNA for
connections to plant host systems and the IBM PC network, as well as
