c# communicates with Siemens plc

Preface: The tools used in the example are Portu v15 + advanced v5.0 + s7netplus. I write this because there are too few introductions to PLC on the Internet, and the information is scattered. As a beginner, I took too many detours here. So record it. And some common bugs and things that need attention […]

ELK handles Spring Boot logs, nice!

Hello everyone, I am Bucai Chen~ In the process of troubleshooting online anomalies, query logs are always an indispensable part. In most microservice architectures used today, logs are scattered on different machines, making log query extremely difficult. If a worker wants to do his job well, he must first sharpen his tools. If there is […]
