摘要： A programmable analog I/O circuit for use in an industrial control system has a first mode of operation as an input circuit and a second mode of operation as an output circuit. In the first mode of operation, a device-side I/O terminal is adapted for receiving an analog input status signal from an analog input device. In the second mode of operation, the device-side I/O terminal is adapted for transmitting an analog output control signal to an analog output device. According to another aspect, a programmable I/O circuit that drives an output device in an industrial control system comprises a plurality of configurable gain stages and a plurality of programmable isolating links. The plurality of programmable isolating links are coupled to the plurality of configurable gain stages and are programmable to determine a series or parallel arrangement of the plurality of configurable gain stages. The output control signal produced by the parallel arrangement is a high current, low voltage output signal as compared to the output control signal produced by the series arrangement. According to another aspect, an integrated circuit fabricated on a single semiconductor chip comprises an I/O interface, a control/logic circuit, and a communication interface. The integrated circuit may be advantageously used to provide a highly distributed industrial control system in which control is distributed all the way to the device level.

摘要： A control unit (38) provided on each of a plurality of operating units for integrating the whole of such an operating unit group that operating units performing a certain operation plurally aggregate and making the same perform regularly operation control includes a signal transmission part (33 and 34) and a signal receiving part (35 and 36) for communicating with the adjacent operating unit, and a connection determination part (37) determining whether or not it is located on a predetermined start position forming a start point of integrated control in the operating unit group on the basis of relative positional relation obtained as a result of performing a communicating operation for deciding the operating unit as a master operating unit when determined as located on the start position while deciding it as a dependently operating slave operating unit when determined as not located on the start position. Thus, an operation integrated control method in which the operating unit can determine whether it is the master operating unit or the slave operating unit itself and a control unit therefor are provided.
