Abstract

A system for controlling an electromechanical system comprised of a number of electromechanical devices such as solenoid operated valves, motor, relays and other devices. The control system is comprised of a central processing unit and control software plus suitable interface circuitry to convert the digital data from the central processing unit into suitable control signals to operate the electromechanical devices. The control software is characterized by the ability to allow users to either select preprogrammed sequences of commands to be executed by the computer or to program unique sequence at either of two levels of complexity. User access privileges may defined by the system manager such that certain users may not be allowed to program their own sequences, while other users may be allowed to program their own sequences only on the first level of complexity but not the second, while a third group of users may be allowed to program on either of the programming levels or to run the preprogrammed sequence as defined by the system manager. The two levels of programming complexity are a high level and an expert level where the command set on the high level consists of a plurality of commands each of which represents a macro.
