title = "Integration of PLCs and databases for factory information systems",
abstract = "It is explained in some detail and in tutorial fashion how PLCs (programmable logic controllers) can be integrated into information systems for day-to-day use on the factory floor. How a PLC is used to collect real-time data and is interfaced to a low-cost supermicrocomputer for production monitoring and FIS (factory information systems) purposes is described. It is pointed out that the whole issue of real-time data collection and control is greatly simplified by the use of PLCs provided that time is not a critical factor. As the PLC program task becomes more complex, the scan time degenerates.",
