In Modbus it is customary to encode addresses and data in the big-endian format, when bytes are starting with the high: for example, when transmitting the hexadecimal number 0x1234, the device will first accept the byte 0x12, and then — 0x34. To transfer data of another type, for example, float numbers, text strings, date and time of day, etc. the manufacturer can choose its own method of encoding — for data decrypting it is important to get acquainted with the specification of the device manufacturer. | |||
