该顺控器主要由输入矩阵、步进器、输出矩阵三部分组成。采用输入矩阵,使得输入的现场转移信号具有通用性,可以重复使用。同时输入信号可以在矩阵输入端进行“与”、“或”等逻辑运算。在矩阵中将有关的横竖母线“短接”来把信号引至步进器中相应的程序上。短路连接点如图中的·所示。 The sequencer mainly by the input matrix, stepper, output matrix composed of three parts. The use of input matrix, making the input field transfer signal has versatility, can be reused. At the same time input signal can be in the matrix input “AND”, “OR” and other logic operations. In the matrix will be related to the vertical and horizontal bus “shorted” to lead the signal to the corresponding program in the stepper. Short circuit connection point as shown in the figure.
