Abstract
A parallel process controller capable of expandable, parallel operating multi-function control of processes without degradation of performance. The process controller comprises up to N (where N is a positive integer) programmable command memory modules, and also comprises data memory modules, an input/output system, a high speed data bus (N-bus) and a general timing and control unit. Each command memory module performs the functional equivalent of a central processing unit with storage of instruction lines designatable by a user via a programming panel. Each command memory module operates autonomously, without regard to the other command memory modules and cyclically solves each of the user instruction lines in a short, fixed length of time. Each data memory module supplements data storage in the command memory modules. The N-bus is a high speed data bus that cyclically interconnects for a fixed length of time each command memory module during one of N control signals generated by the general timing and control unit, to any of the data memory modules and to the input/output system. During this length of time, the selected command memory module may address, read, or write in any loc…
