摘要： A serial control apparatus includes a main controller (2) and a plurality of nodes (3) each serving as an auxiliary controller normally serially arranged on a loop-shaped signal transmission line (1). Each node (3) extracts data for the present node among from the data delivered from the main controller (2) as time elapses so as to allow the terminal units (A) associated with the present node to be properly controlled. In addition, the node inserts the output data from the terminal units (A) into a time slot corresponding to the present node and then delivers to the signal transmission line (1) the output data which in turn are transferred to the main controller (2) via other nodes on the downstream side. To assure that the data extracting circuit operates properly, two latching circuits, i.e., first and second latching circuits (311, 312 to 315) are serially arranged in a signal passage by way of which the extracted data are fed to a driver (316) for the corresponding terminal units.

摘要： An apparatus for carrying out serial control and a method of controlling the apparatus wherein the apparatus and the method are employable for a centralized control system for various machinery such as press, machine tool, ship, aircraft or the like machine as well as a centralized control system for unmanned conveyor, unmanned warehouse or the like installation. The apparatus comprises a plurality of nodes connected in series one after another and a main controller connected to the nodes. A data row length of data included in a signal from the node at the preceding stage is counted by a data row length counter and the counted data row length is compared with data row length data included in the signal from the node at the preceding stage. When the counted data row length does not coincide with a data row length representative of the data row length data, this non-coincidence is determined as a data row length abnormality thereby to generate an error signal. The data row length data included in the signal from the node at the preceding stage is converted into data row length data corresponding to a row length of data outputted from own node and the converted data row length data are delivered to the node at the subsequent stage.

摘要： In a measuring differential amplifier having first and second input terminals for subtracting a first signal applied to the first input terminal from a second signal applied to the second input terminal to obtain a subtraction and for outputting a signal corresponding to A times of the subtraction, a circuit for reducing an offset generated during measurement. Prior to the measurement, the second signal is applied to the first and second input terminals so that the differential amplifier outputs a voltage corresponding to A times of a difference between the second signals, i.e., A times an offset voltage. At this time, the differential amplifier is connected at its output terminal to one end of a capacitor grounded at the other end so that the voltage corresponding to A times of the offset voltage is applied to the capacitor for charging. During the measurement, the output terminal of the differential amplifier is disconnected from one end of the capacitor so that the voltage charged in the capacitor is applied to the adder and multiplied by 1/A to become again the offset voltage. The adder adds a signal indicative of the offset voltage to the first signal to obtain an addition signal and supplies the addition signal to the first input terminal of the differential amplifier. Thus, the input offset voltage is canceled by an offset voltage newly generated at the differential amplifier.

摘要： An apparatus for carrying out serial control includes a single main controller and a plurality of node controllers for directly controlling a variety of sensors and actuators. The node controllers are serially connected to the main controller. The main controller receives a data signal row which is successively transferred through the node controllers and then indirectly and centrally controls sensor data derived from the sensors, as well as actuator control data transmitted to the actuators. Data is transmitted from the data signal row to the sensors or the actuator to be controlled and vice versa in each node controller. An error code is added to the data signal row which is to be transferred to a succeeding port under logic conditions indicating the occurrence of an error. The occurrence of an error is confirmed by inspecting an error check code which is previously added to the data signal row to check whether an error has or has not occurred between the node controllers. The error code for indicating the occurrence of error is added to the data signal row which is inputted into the relevant node controller.

摘要： This apparatus for carrying out serial control comprises a plurality of node controllers each including a group of sensors (21S to 2nS), a group of actuators (21A to 2nA) or the like terminal components and a main controller for controlling the node controllers and the terminal components in an annular configuration or in a daisychain-shaped configuration. The main controller sends a frame signal which includes a first identification code (STI) indicative of the head position of sensor data and a second identification code (STO) indicative of the head position of actuator controlling data in one frame. Each node controller including a group of sensors feeds its own sensor data to a location just behind the first identification code of the received frame signal and sends to the subsequent stage the frame signal delayed by a length of the sensor data having the received frame signal fed thereto, subsequent to the signal having the sensor data fed thereto. Further, each node controller including a group of actuators extracts its own actuator control data from a location just behind a second identification code of the received frame signal and then sends the frame signal having the actuator control data extracted therefrom, subsequent to the frame signal which has been delayed by a length equivalent to the actuator control data having the received frame signal extracted therefrom.

摘要： A device is provided to prevent erroneous operation of an object to be controlled connected to the controller if the clock is interrupted. When a clock monitoring unit (15) detects that no clock pulse signal (CL) is generated from a clock generating unit (14) in a controller (10), a D flip-flop (13) is forcibly turned off, so that no drive signal is given to the actuator that is the object to be controlled. Moreover, a clock monitoring unit (42) in a controller (40) detects whether a clock pulse signal (CK1) is being sent from a controller of the preceding stage or not. When the clock pulse signal (CK1) is being received, the clock monitoring unit (42) sends the clock pulse signal (CK1) to the actuator that is the object to be controlled via a data processing unit (44). When the clock pulse signal (CK1) is not detected, a clock pulse signal (CK2) of a self clock generating unit (41) is sent to the actuator that is the object to be controlled via the data processing unit (44).

摘要： To reduce the number of signal lines for connecting an current detector and a solenoid electrically.Between solenoids 1-1 and 1-2 and switches SW-1 and SW-2 and on the high sides with respect to the individual solenoids, respectively, there are connected current detectors 4-1 and 4-2. The end portions of the solenoids 1-1 and 1-2 on the individual GND sides are made common. The number of signal lines for connecting a controller and the two solenoids may be “2+1=3”. Therefore, the number of terminals (or the pin number) of a connector 3 may also be “2+1=3” (P1 to P3). The current detectors 4-1 and 4-2 detect the electric currents to flow to the solenoids 1-1 and 1-2. In the case of an incomplete grounding, for example, it is possible to detect an overcurrent to flow to the solenoids.
