西门子模块代理商PLC模块功能特点：
1、可靠性高：由于PLC大都采用单片微型计算机，因而集成度高，再加上相应的保护电路及自诊断功能，提高了系统的可靠性；
2、编程容易：PLC的编程多采用继电器控制梯形图及命令语句，其数量比微型机指令要少得多，除中、PLC外，一般的小型PLC只有16条左右。由于梯形图形象而简单，因此容易掌握、使用方便，甚至不需要计算机知识，可进行编程；
3、组态灵活：由于PLC采用积木式结构，用户只需要简单地组合，便可灵活地改变控制系统的功能和规模，因此，可适用于任何控制系统。

S7-1500模块计数工艺模块，西门子PLC S7-1500系列的计数工艺模块，可以实现高速计数和测量,并能对快速信号进行预处理;它可以在西门子PLC S7-1500的CPU中进行集中操作，也能在ET200分布式I/O中操作。计数模块可以连接信号增量式编码器，24V非对称，带有或不带方向信号的脉冲编码器，正向或反向脉冲编码器等。它可以实现频率，周期，速度的测量，每个计数通道有3个DI，用来启动，停止，捕获及同步，2个DQ用于计数比较器和限值。西门子S7-1500RS232通讯模块6ES7540-1AD00-0AA0 SIMATIC S7-1500， CM PTP RS-232 BA 通讯模块针对 串行连接 RS-232， 空闲端口，3964(R)，USS， 19200 kBit/s， 9针 Sub-D 连接器SMARTS7-1500产品简介制造行业中的创新系统解决方案——模块化控制器SIMATIC S7-1500控制器具有模块化、结构紧凑、功能等特点，适用于多种应用，能够**现有投资的长期。由于该控制器具有可扩展的灵活设计，符合工业通讯高标准的通讯接口，以及的集成工艺功能，因此它可以作为一个组件集成在完整的综合自动化解决方案中。

二管是用半导体材料(硅、硒、锗等)制成的一种电子器件 。它具有单向导电性能， 即给二管阳和阴加上正向电压时，二管导通。 当给阳和阴加上反向电压时，二管截止。 因此，二管的导通和截止，则相当于开关的接通与断开 。
