In industrial control applications, the returned data is often stored in binary format, and the binary data represents a hexadecimal data content every 4 bits. During parsing, a single Byte usually occupies eight digits (bit). 4 bits at the top indicate a hexadecimal data, and 4 bits at the bottom indicate a hexadecima

In industrial applications, the returned data is often stored in binary form, and these binary data represent a hexadecimal data content per 4 bit. Parsing, often a byte (byte) occupies 8 bits (bit), high 4bit represents a hexadecimal data, low 4bit represents a hexadecimal data
