Description: 西门子S7-1200 PLC支持多种协议通过以太网通讯方式，如OPC、TCP、S7、MODBUS-TCP等。TCP方式相比其它协议，具有更多的灵活性，更快的数据响应等优点，本人即介绍LabVIEW通过TCP方式与S7-1200 PLC通信。
S7-1200 PLC的TCP通信方式，称之为“开放式用户通讯”，通过以太网发送或读取数据。(SIEMENS S7-1200 PLC supports a variety of protocols through Ethernet communications such as OPC, TCP, S7, MODBUS-TCP, and so on. Compared with other protocols, TCP has more flexibility, faster data response and so on. I introduce LabVIEW to communicate with S7-1200 PLC through TCP mode.
S7-1200 PLC TCP communication, known as "open user communications", send or read data over ethernet.) Platform: |
