Abstract
A new manufacturing, engineering, and laboratory facility for IBM in Tucson, Arizona utilizes a hierarchical distributed digital control system for monitoring and control of air conditioning and space heating systems plus central utility systems. The hierarchy consists of a central IBH Series/1 system for optimization and operator interface, a sequential logic control processor for management of a chilled water storage tank farm and remote microprocessor units located at each building for control of air conditioning units, fans and miscellaneous equipment. This paper describes the overall system architecture and discusses some of the installation experiences as well as the system performance during the first year of operation.
