Today, I have gathered some ideas and methods on how to master PLC programming. I hope that after accepting this recommendation, everyone can have a general learning approach to PLC programming and independently apply PLCs to complete programming. 1. Basic Hardware Knowledge Before programming, it’s essential to understand some basic hardware knowledge. It’s best to … Read more
Everyone knows that industrial production and technological development are inseparable from the automation control of PLCs. PLC can be broadly understood as: a centralized relay extension control cabinet. In practical production applications, PLC greatly reduces the cost of industrial control and enhances the centralized management and automatic control of equipment. To learn PLC well, it … Read more
Search on WeChat Technical Training Before selecting a PLC, we must first determine the system plan. Once that is established, we can choose the manufacturer and model. Do you know how to make these selections? This article provides detailed introductions from manufacturers and models to input/output (I/O) points, control functions, etc., helping you choose the … Read more
