Pacer: A Microprocessor-Based Process Control*

Automated manufacturing processes are frequently controlled by a centralized mini-computer which monitors system status and controls individual machines using parameters such as temperature, number of rejected units, etc. Systems of this nature suffer from inflexibility in that expansion or other changes require re-programming of the control computer. GARD has devised a control system called PACER which permits increased flexibility through decentralized control. Each machine is individually controlled by its own microprocessor; expanding or modifying the system is thus greatly simplified.
