Abstract

This paper presents the design of a control system which uses the personal computer (PC) as a versatile and indispensible system component for process development, control, and on-line supervision. The incorporation of the PC as an interface to a programmable logic controller (PLC) is shown to be an analytically useful link in acquiring the data necessary for process development, while the PC utilization continues to be cost effective for systems with existing processes. A ladder logic programming philosophy along with the PC interface, is presented which initially allows for the construction and the safe operation of the system in the process development phase. Examples of MS-DOS BASICA source code used with a commercially available Allen-Bradley to PC driver package are included to illustrate the programming techniques which yield the versatile PC/PLC interface.
