2.9.2 Analog input data read-out
[Function Code: 04(04 H)]
Only a specific quantity from the specified number "continuous number analog input (2 byte : 16-bit)
data" is read.
The data is split into high 8-bit and low 8-bit, arranged in numerical order and composed into
response message data.
Response example: Same as "function code 03", only the start number (relative number) is
"reference number minus 30001".
2.9.3 Analog setting value write
[Function code: 06(06 H)]
Assign analog setting value for given number to specified value.
Example: set fixed temp operation temp setting to 100 for slave 1.
