PLC programming is a problem that can easily cause headaches for engineers. This article will detail the tips of PLC programming from three aspects: ladder logic and PLC scan, BCD code and reusable code. The BCD code is a binary code of a decimal number, where each number is represented by a specific bit, usually 4 or 8 bits, which is quite different from the way humans calculate. This splitting will cause problems for PLC users. PLC's reusable code gives users the flexibility and allows building structures that can be exported from one application to another.
