    摘要： A controller for electrical circuit systems and apparatus, the controller being programmable with logic instructions representative of circuit nodes of a ladder diagram. As compared to the prior art, this controller is simple to program and does not require any modification of the conventional ladder diagram. The controller comprises a store WNM of the logic values of the circuit nodes and a store CCM of the logic values of the control coils in the ladder diagram. The control program is stored in main memory MM. Processing circuit LC1 is provided for computing and updating the logic values of the circuit nodes or control coils based on the previous stored values and input signals from input circuit IB, and for storing the updated logic values in the stores WNM and CCM.

    摘要： A system and method for controlling operation of a plurality of elements in an automated process, such as a production process, and indicating error conditions as they occur. Each unique set of input and output conditions of the various system elements defines a unique logic state or zone. Thus, there are defined a multiplicity of valid system logic states or zones, each having a unique input/output image. A predetermined sequence of zones, productive zones representing designed machine operations, is stored in a zone table. All zones not explicitly defined in the zone table are automatically treated as error zones. A zone engine automatically cycles to observe any change in input/output image. Any change in inputs from the various system elements automatically transfer action to the unique zone associated with such inputs, resulting in corresponding changes in control outputs to the system elements and/or display an error message as appropriate.
