The OUT DATA (4ch) is used for storing commands and parameters to the AD-4402.
The IN DATA (8ch) is used for storing reply data from AD-4402.
Caution
The interface needs 8 bytes for OUT DATA and 16 bytes for IN DATA in the
memory area of the PLC. Avoid crossing memory area of other slave devices.
These use BCD code.
