A Clock for the Manufacturing Systems Integration Testbed

Published

Author(s)

Abstract

This paper describes a software module that provides timing services to the MSI, a Manufacturing Systems Integration Testbed in the automated factory.

The software alarm clock provides services to other MSI software including:

  • Synchrony
  • Real-time, or non-real-time adjusted in a variety of ways
  • Alarms at relative or absolute internals.

By providing a central time service, these services are provided more reliably, efficiently, and flexibly than could any client on its own.

This paper describes how the timing software was implemented, what its interfaces are, and how to design and write programs that use it.
