Why can't you see the application of PLC in the field of automotive electronics? !

First of all, PLC is mainly used in the field of non-standard automation equipment. Is a relatively open platform, but anyone who knows a little about the program can apply it. Privacy or property rights will be threatened. Although there is password protection, there are many softwares and people who can decipher PLC passwords.

In order to protect their own property rights, the standard equipment is a control panel developed by their own team, which is essentially the same as PLC, but it is an embedded system with underlying programs. Just like the operating system of our computer. Its underlying program is not open, and its confidentiality is greatly improved. Automobile electrical system is such a complex system. A lot of data are empirical data that they have summed up in years or decades. It must be kept secret.
