4.6 Details of function codes
Replies by each of function codes are shown below.
4.6.1 Readout of analogue settings
[Function code：03（03H）]
Readout will be made for "Analogue settings (2 byte：16 bit)data" whose numbers are continuous
for the specified number of values starting with the specified number. Data is divided into high 8
bits and low 8 bits, which then will be arranged in the order of their numbers to form data for the
reply message.
Example: Readout of fixed temperature operation SV temperature setting, fixed value auto start SV
temperature setting, fixed value auto start time/clock time select setting of slave 1.
(Readout of three analogue settings of slave 1 from reference #40001 to 40003)

Note: Starting number (relative number) is "Reference #－40001".
Note: The number of data pieces is the number of bytes of the data.
(This is different from the requested number. In the example, the requested number is three
while the number of pieces of the data is six.)
