摘要： A device for transmitting a synchronous data which transmits data asynchronously from a first system controller to a second system controller. Transferred data is doubly stored in a first and a second memory. The data outputted from the first system controller is written in the first and second memories alternatively in correspondence to the data transmission of the first system controller. When the writing is completed, the second system controller reads the data in one of the memories in which the writing has been completed earlier than the other, and the next writing by the first system controller is performed to the latter memory. Thereby, the access to one of the system controllers need not wait temporarily, the transmission of a block of a large amount of data is not interrupted during the access to each controller, and accurate high-speed data transmission accompanied by no error can be performed.

摘要： A serial control apparatus in which nodes to which are connected one or more sensors and one or more actuators are connected in series in the form of a closed loop including a main controller which sends data frame signals including a first special code, a second special code and output data for said actuators. Each of said nodes adds the data received from its associated sensor to the end of the first special code and picks up the output data for its associated actuator from the end of said second special code. The main controller controls the interval for sending the data frame signals depending upon the number of sensors and the number of actuators detected based on the initial frame signal that includes the first special code, the second special code and data for detecting the number of actuators, in order to improve the transmission efficiency and to carry out the control in real time.

摘要： A serial control apparatus in which nodes to which are connected one or more sensors and one or more of actuators are connected in series in the form of a closed loop including a controller which sends data frame signals including an output data for said actuators. At each node, the data from its associated sensors are added to said data frame signals and the output data for its associated actuators are picked up from the data frame signals. The controller includes first setting means for setting output data for the actuators of the individual nodes, second setting means for setting numerals that indicate the order of transmitting the data from said controller to the nodes of the individual nodes, and data forming means for forming a sequence of output data for the actuators in said data frame signals according to the contents set by the first and second setting means, enabling the data to be allocated to the nodes simply and correctly even when the nodes are added or deleted.

摘要： This invention relates to a serial controller in which nodes connected to one or more sensors are connected serially together with a main controller, the main controller sends out predetermined data frame signals at a period sufficiently shorter than the time intervals at which the data detected by the sensors vary and each node adds the data sent from the connected sensors to the data frame signal. A main controller compares the data from the sensors contained in an inputted data frame signal by predetermined times when receiving the data frame signal. Only when the result of the comparison at the predetermined times coincide, the data of the respective sensors are received as true data. Any error generated over the whole path through which the data outputted from the sensors are transmitted to the main controller via the respective nodes can be detected.

摘要： A series controller consists of node controllers having terminal equipment such as sensors (21S to 2nS) or actuators (21A to 2nA), and a main controller that controls the terminal equipment, the main and node controllers being connected in the form of a ring or a daisy chain. The main controller produces a frame signal which includes a first identification code (STI) that indicates a head position of the sensor data and a second identification code (STO) that indicates a head position of the actuator control data in a frame, and sends such a frame signal to the node controllers. Each of the node controllers having the sensor adds its own sensor data to the frame signal immediately after the first identification code of the received frame signal and sends a frame signal, which is based on the received frame signal and delayed by the length of the sensor data added thereto, to the next step subsequently to the received signal to which the sensor data is added. Further, each of the node controllers having the actuator picks up the actuator control data related to the node controller itself immediately after the second identification code of the received frame signal and sends a frame signal from which the actuator control data has been picked up to the next step subsequently to the frame signal which is based on the received frame signal and delayed by the length of the actuator control data that is picked up from the received frame signal.

摘要： A data pick-up circuit for a serial controller is formed, usually of a main controller (2) and a plurality of nodes (3) as sub-controllers which are connected in series in a loop transmission line (1). In this circuit, each node picks up the data directed thereto out of time-series data sent from the main controller to control a terminal (A) connected thereto, and sends the data produced from said terminal to the transmission line through a time slot corresponding to said node. The data is transmitted to the main controller via another node on the downstream side, the data pick-up circuit being employed for each of the nodes to prevent the terminal connected to the nodes from operating erroneously. One method consists in connecting first and second two latch circuits (311, 312 to 315) in series with a signal path through which the data picked up are supplied to a driver (316) of the corresponding terminal. When error or error history is detected in transmitting the data, the data is prevented from being latched to the latch circuit placed on the driver side, such that erroneous data or unreliable data will not be supplied to the driver.

摘要： An error display device of a data transmission system in which plural nodes are connected to a main controller to transmit data and the main controller judges the content and position of an error from the error signal in a transmitted data frame signal and displays them on the error display device, the error display device being characterized in that the content stored in a temporarily storing means for storing temporarily signals representing the content and position is not updated every time an error signal is inputted but updated by the command of an operator. Even if all the displayed contents of the errors are difficult to confirm when the errors generate frequently at many places, the contents of the errors can be confirmed positively by using the error display device.
