Project description
Introduction Let’s start with what this project is about. The creator built a simple but fully functional HMI panel for the Siemens S7-1200 PLC using a custom STM32 board named USM01, and he added a W5500 to handle Ethernet communication. So instead of using a commercial touch HMI, this setup lets you monitor values, change parameters, and trigger actions directly from a small LCD and three buttons. It’s small, reliable, and industrial-friendly. WIZnet Product Integration Now let’s look at how the WIZnet device fits in. The W5500 is used as the main Ethernet engine, and it communicates with…
