The buffer naming (output and input) is always from the customer's point of view, which is from the master (PLC).
The data are transmitted using Intel format, where the lower byte is being sent first.
Since the communication goes over words (16bit), each one byte signal is stored in a lower byte of the word, and the upper one is a padding one, not used. The lower byte is also called LSB (Least Significant Byte)
