An integrated diagnostic system for a process controller

The Oak Ridge National Laboratory Instrumentation and Controls Division is developing an integrated diagnostic system to aid a technician in diagnosing faults in a complex process controller. The integrated diagnostic system, which is being developed to run on 80386 machines in the Smalltalk language, will include an expert system to make a diagnosis, an on-line ''hypermedia'' manual (which includes equipment manuals and video) to supply additional help and reference material, and an automated procedure guide to take the technician through complex procedures for tasks such as parts replacement. 3 refs., 6 figs.
