摘要： A communication protocol employing dummy input and output values is used in communicating blocks of data between an industrial controller and its I/O modules while preventing premature use of partially transmitted data by the I/O modules yet without the need for special handshaking type circuitry or the continuous overhead of such handshaking protocols.

摘要： An industrial control output device is provided which provides electrical isolation between device power and field power. The device includes two isolation devices, one of which is adapted to energize a power switching device, and the other is adapted to de-energize the switching device. The output device thus minimizes or reduces EMI/RFI emissions and provides fast switching times in selectively providing power to a load. In addition, the invention includes a method of providing power to a load in an industrial control system, which allows fast switching of a digital output with minimal or reduced EMI/RFI emissions.

摘要： The present invention provides an efficient method of transferring multi-word data across a fixed width parallel bus normally transmitting a single word at a time by allocating part of the bus word to the transmission of a fractional address dividing the given addressing space into subaddresses or "fractional addresses". A data transfer request provides the desired fractional address and the data transfer response returns the fractional address value and the portion of the multi-word data corresponding to that fractional address.

摘要： The density of I/O circuits on input and output modules in a programmable controller is doubled, while the number of optically coupled circuits is reduced, by transmitting data serially through one of the optically coupled circuits. Optically coupled circuits are also used for address and test signals and error-checking circuitry is provided to sense failures of the optically coupled circuits. The optically coupled circuits on each module are connected between two universal large scale integrated (LSI) circuits. The universal circuit can be operated on either the processor side or the machine side of either an input module or an output module by selecting a corresponding one of its four modes of operation. The multiplexing electronics on the input and output modules, aside from the optically coupled circuits, is integrated into just two components, and only one universal component is required for replacement of either of these two.

摘要： A programmable controller has a chassis which removably holds a plurality of functional modules. The chassis has a backplane with conductors and connectors that electrically connect the modules. These conductors carry module enable, read, and write control signals, as well as byte addresses and data. Another conductor carries a signal, which when true designates that files of data, as opposed to discrete bytes of data, are being exchanged over the backplane data conductors. Each module stores identification and diagnostic data as a number of individually addressable bytes. The identification and diagnostic data is obtained from a given module by sending an active module enable signal to it. At the same time the given module is sent inactive read and write signals and an active data file transfer signal. This combination of signals is used only to read the identification and diagnostic data and is not used to exchange other types of data with functional modules.

摘要： A method and circuitry for communicating both byte transfer I/O data and file transfer I/O data to an individual I/O module through an equipment chassis backplane in a programmable controller. The byte transfer data is real time I/O data representing the status of I/O devices on an industrial machine or process. The file transfer data includes fault diagnostic data concerning conditions of the I/O devices in addition to their ON or OFF state. The circuitry is integrated into a single integrated circuit. The methods and circuitry are applicable to two different modes of addressing, one mode being used by earlier programmable controller processors and adapters and the other mode being used by newly developed processors and adapters.
