SEW 3001-403-4-06 第二通信协议的类型太多。仅西门子plc品牌就有很多。现在，让我们来谈谈这些类型:

串行端口协议有:

1) MODBUS RTU通信协议

2)现场总线通信协议

3) USS通信协议

4) PPI通信协议

5) MPI通信协议

6)自由港

以太网通信协议包括:

1) MODBUS TCPIP通信协议

2)opc通信协议

3)等开传输控制协议

4) UDP通信协议

5) PROFINET通信协议

6) S7协议

西门子的主要协议在这里。根据笔者的经验，MODBUS RTU通信协议和MODBUS TCPIP通信协议是最常用的必须掌握的协议。因为这两个协议被广泛认可和使用，基本上自动化工厂的每一个自动化设备都支持这两个协议，所以这两个协议必须由一个合格的自动化工程师来掌握，可以结合plc视频教程来学习。
