    Abstract: A method and apparatus for incorporating fuzzy logic into a feedback controller is provided. An error signal and the derivative of feedback or error is provided to the fuzzy logic to develop a proportional and differential signal, the differential signal is subsequently integrated and added to the proportional signal to create a control output of the controller. The fuzzy rules of the fuzzy logic decrease the integral term under situations that might lead to "wind-up".

    Abstract: A multi-tasking operating system for real-time control of industrial processes integrates ladder type programs and state-type programs by viewing each as a series of instructions with an implicit pointer list pointing to the next instruction. A fixed number of instructions of each program task are executed after which the effective pointer to the next instruction is stored toward the next time that task is invoked. Multiple tasks that need to be coordinated can be linked with subtasks that can be guaranteed complete execution by allocating sufficient instructions to those subtasks.

    Abstract: An eight-bit microprocessor sequentially reads controller type instructions from a memory and applies the operation codes of selected ones of the instructions to a hardwired Boolean processor. The microprocessor also couples status words between an I/O image table stored in the memory and the I/O interface racks which connect the programmable controller to the machine being controlled. In general, those controller type instructions which are word oriented are executed by the microprocessor and those which are single-bit oriented are executed by the Boolean processor. The Boolean processor is operable in combination with the microprocessor to examine selected status bits in the I/O image table and to set selected status bits therein to a logic state which is determined in part by the state of the examined status bits.

    Abstract: An industrial control processor is employed in a numerical control system to operate the servo mechanisms on a machine tool in response to a part program stored on a tape. The industrial control processor includes unique hardware and software features which also allow it to operate as a programmable controller to control the discrete digital devices associated with the machine tool. The industrial control processor is programmed with a conventional computer type instruction set to perform numerical control functions and is programmed with a programmable controller type instruction set to perform the machine dependent logic functions. The resulting system maintains the state-of-the-art capabilities of a computer numerical control (CNC) and adds to it the flexibility and programming ease of a programmable controller.

    Abstract: A programmable controller interfaces a numerical control system to sensing and operating devices that control the auxiliary functions on a machine tool. In the controller a microprocessor is coupled to a random-access memory (RAM) and an electrically alterable read-only memory (EAROM) through an address bus and a data bus. The RAM stores a user control program and an I/O image table that depicts the status of the sensing and operating devices on the machine tool. Under program control the microprocessor verifies the contents of the RAM and copies the verified contents into the EAROM. If the contents of the RAM are altered or lost, the master copy of data stored in the EAROM is reloaded into the RAM.

    Abstract: Fault detection hardware is employed at the I/O interface racks of a programmable controller to detect fault conditions which may occur there. An I/O fault line is connected in daisy chain fashion between the I/O interface racks and the controller processor, and when a fault is indicated at any of the I/O interface racks, it is communicated to the controller processor through this line. The indicated I/O fault freezes, or holds, a microprocessor in the controller processor, and if the I/O fault persists for a preselected time interval, all operating devices connected to the programmable controller interface racks are decontrolled. A watchdog timer is also provided in the controller processor for detecting malfunction conditions which may occur at the processor. When such a condition is detected, the operating devices connected to the programmable controller interface racks are decontrolled.
