8-5-2. Reading analog setting value [Function code: 03 (03H)]
From the specified number, only the number of specified units read the number series 'Analog
setting value (2 bytes: 16 bytes) data'. Data consists of response message data that is arranged in
numeric order and is split into high order 8 bit and low order 8 bit.
Example) Reading executing SV, executing time ‘hour’, and executing time ‘minute’ of slave 1.
(Reading 3 units of analog setting value reference number from 49003 to 49005 of slave 1.)

Note) Starting number (Relative number) is 'Reference number - 40001'.
Note) Data count is the number of bytes of data.
(It differs from request units. In the example request unit count is 3 units, data count is 6
units).
Note) There is a limitation on the number of data units of the message (This device can be sent)
that can be received at a time.
(See section 8-4.)
8-5-3. Reading analog input data [Function code: 04 (04H)]
From the specified numbers, only the number of units that are specified 'Analog input (2 bytes: 16
bytes) data of the number series' are read. Data is split into high order 8 bits and low order 8 bits and
is arranged in numeric order and consists of the data of response message. Response example is
similar to that of 'Function code 03'. However starting number (Relative number) is 'Reference
number-30001'.
Example of SV = 100 and time = 10:20
<ASCII mode error check> (*CRC(L)(H) of the above are LRC as follows.)
