6�3�7�14�- Digital inputs
The Input Name configuration variable occupies 4 registers.
The Units configuration variable occupies 3 registers.
All other variables occupy 1 register each.

(1) When programming a value of more than 1, programme the impulse operating mode and energy meter factor
for this mode simultaneously.
(2) the characters must be sent in hexadecimal.
Note: The 11 registers must be written and read at once (as a group), otherwise it will respond
with an error.
