Introduction Last week, the new electrical engineer at the company was frustrated again. Faced with a production line failure, he stared blankly at the PLC ladder diagram on his computer screen for half an hour, finally admitting with a red face: “I don’t understand this logic…” This was already the third time this month. The … Read more
The hardware of a PLC mainly consists of several parts: the Central Processing Unit (CPU), memory, input units, output units, communication interfaces, expansion interfaces, and power supply.The CPU is the core of the PLC, while the input and output units serve as the interface circuits connecting field input/output devices to the CPU. The communication interface … Read more
