摘要： An interchangeable keyboard application module is connected to a video monitor module in a computer terminal to provide sequences of processor instructions and a keyboard for performing a plurality of selectable applications. The video monitor module includes a CRT display, a serial I/O interface and a processor that processes characters received through the serial I/O interface for display on the CRT screen whether or not the application module is attached. The processor in the video monitor module detects the connection of the application module, and then selects its instructions from a memory in the application module first, to prompt the selection of a mode of operation for the terminal, and second to execute the selected mode of operation. The application module uses a plurality of keyboard overlays, each corresponding to a respective mode of operation. In a specific embodiment two of the modes of operation are programming applications related to programmable controllers.

摘要： A rack adapter for a programmable controller is included in each of four remotely located I/O interface racks that are connected in series to a central processor. The rack adapter includes a rack interface processor under program control which converts serial data received from the central processor to parallel data that is written into I/O modules in its rack. The rack interface processor also converts parallel data from I/O modules to serial data, which is sent back to the central processor through a select data out circuit in proper sequence with data from the other racks. The rack interface processor initiates the decontrol of machines connected to the four racks if a major transmission fault occurs, but the rack interface processor is tolerant to transmission errors caused by electrical noise. A dual-frequency clock drives the rack interface processor, and interface circuitry which is operable at two bit-transmission rates connects the rack interface processor to the communication channel, which can range up to 10,000 feet from the central processor.

摘要： An active programmable controller services I/O racks which contain circuits that interface with sensing devices and operating devices on a machine being controlled. A back-up programmable controller monitors this I/O data to maintain a current I/O image table in its memory. Other status data is coupled to the back-up controller from the active controller through a peer-to-peer communications link. If a malfunction occurs in the active controller, the back-up controller is signaled to switch to the active mode in which it assumes control of the operating devices on the machine being controlled.

摘要： A processor-based control system including a host processor, a data receiver device, a system memory, and an intelligent DMA controller. The DMA controller includes a pre-parsing section. The pre-parsing section interrogating a received data packet to determine whether the received data packet contains an error, is valid, is a null packet or whether the host processor must be contacted.

摘要： A programmable controller suitable for operating a machine to carry out programmed functions includes a plurality of program processors. Each of the program processors being operable to execute simultaneously a different user control program that directs the operation of the machine to perform specific functions. Each of the processor means is contained within a separate module which also includes a memory for storing the user control programs that are to be executed by that processor means. A mechanism is also provided to control the sequence in which the user control programs are executed and which of the processor means executes a given control program. At least one input/output interface circuit controls the gathering of data from various external sensors and in response to output data received from the processor means, controls the operation of actuator devices on the machine. The input/output data regarding state of the sensors and actuator devices are stored in a memory within the interface circuit. A system controller supervises the interaction and intercommunication of the plurality of processor means and the input/output interface circuits.
