There are many PLC learning machines on Taobao, including 200-200 and thousands. The price is cheap, but I can only learn to write programs, understand components and connect wires, which can be said to be of no help. If you only know how to write a few instructions, you can say that you are a little reluctant to get started. Thousands of machines are very good, exactly the same as those in the factory, but the price is too high, which can almost enter the training class. I suggest you buy a 1000 one, which is similar to the one in the factory, and you can learn something at an affordable price.

Someone suggested buying PLC, power supply and stepping driver for assembly. It is reasonable to say that it is best to assemble one by yourself, but it is impossible for novices to assemble these things well, and the quantity is small and the price is high. It is better to buy a ready-made one, learn how to use it first, and then disassemble and assemble it yourself, so as to learn things quickly and save money.

This is ok, the price is 750, and there are stepping drivers, stepping motors, lights, sensors and button switches. Although the number is small, the overall classification is quite neat and the information is very complete. Generally speaking, it is cost-effective, and novices can buy this.
