COMPUTER CONTROLLED DISTRIBUTION APPARATUS FOR DISTRIBUTING TRANSACTIONS TO AND FROM CONTROLLED MACHINES TOOLS ABSTRACT OF THE DISCLOSURE A system for controlling a plurality of machine tools in which the central processor communicates data trans- actions to and from a plurality of tool controllers, each of which is operatively associated with a machine tool. Each of the controllers comprises at least one machine tool control unit which is adapted to provide a digital output to the associated machine tool for con- trolling a particular tool function and/or for receiving from the machine tool a digital input indicative of a particular tool condition. The central processor has connected thereto a main multiple channel data bus for conducting data transactions by transferring parallel bits of data to and from the processor. The system also includes a plurality of multiple-channel unit data buses, each of which is connected to one of the tool control units. Data distribution apparatus in the system couple the unit data buses to the main data bus from the processor and serve to distribute the processor transactions to and from the specific tool functions of the controlled machine tools. This data distribution apparatus includes means responsive to a set of distribution signals from the central processor for selectively activating one of the tool control units and for selectively activating only -1- BACKGROUND OF THE INVENTION This invention relates to digital data controlled systems and more particularly to systems for controlling and monitoring an extensive number and variety of machine tools. With the increasing automation of industry, both in manufacturing and in facilities controlling and monitoring, as well as the ever increasing automation of many aspects of life, both in homes and business offices, there is a constant demand for means for increasing the distribution potential of the central processing unit input/output in order to increase the capability of such central processors -2-
