The classic communication scheme between Kingview and Siemens PLC wireless PPI that industrial controllers must learn

■ Program introduction

In the actual system, the human-machine interface and the PLC are usually not together. The central computer is generally placed in the control room, while the PLC is installed in the on-site workshop. The distance between the two is often from tens of meters to several kilometers. If wiring is required, trenching is required, which is more troublesome. In this case, wireless communication is more suitable. Because the wireless PPI protocol has a fast response speed and does not require programming, only configuration is required, so users prefer to use the PPI protocol network. However, the realization of wireless PPI communication requires a dedicated wireless data terminal, and the matching of the setting parameters should also be considered during configuration.

This program uses configuration software as an example to introduce the process of wireless PPI communication between Siemens S7-200 Smart and configuration software. In this scheme, Siemens PLC dedicated wireless communication terminal-DTD434M is used as the hardware device for wireless communication.
