Assignee:

Gould Inc. - Rolling Meadows IL

International Classification:

G06F 1546

US Classification:

364900

Abstract:

An improved programmable controller having the ability to use two different data bases while presenting to the outside world a uniform word size. The programmable controller includes pipeline processing and hardware solution of a user control program in a network node format. A memory management scheme is provided allowing for the direct addressability of one-half million words by utilization of a page register. The programmable controller can be incorporated into a network containing other programmable controllers. The programmable controller also incorporates a multi-task interrupt so that the processor can handle more than one job at any particular time. Input/output tasks are handled logically in the scan solving the user networks rather than being based upon a particular physical area of the controller memory.
