The complete list of MODBUS registers is shown below. If you try to read a register that
is not present, the instrument returns the fixed value 32767. The list of the available
registers can be downloaded in the PC using the function " Download the list of MOD-
BUS registers of the device " included in the Settings sections of HD35AP-S software
(see software instructions).
The following conventions have been used in the tables:
o
Type: b = bit, B = 8 bits (Byte), W = 16 bits without sign (Word), SW = 16 bits
with sign
o
(x10) = decimal value expressed as an integer (e.g., if the content of the register
is 184, the value is to be intended as 18,4).
o
(x100) = centesimal value expressed as an integer (e.g., if the content of the reg-
ister is 500, the value is to be intended as 5,00).
The commands for requesting units of measurement return an index according to the
