SERIAL CONTROLLER.

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.
