8-5-6. Writing multiple analog setting values [Function code: 16(10H)]
From the specified number consider the analog setting value of the specified number of units as
the specified status (ON/OFF). The data is split into high order 8 bits and low order 8 bits is arranged
in numeric order and then sent.
Example) Set as, SV decimal point = 1, SV range, lower limit = -200.0, SV range higher limit = 1370.0
of slave 1.
(Set 3 units of analog setting value reference number of slave 1 from 40206 to 40208.)

Note) Starting number (Relative number) is 'Reference number - 40001'.
Note) If slave address is considered as 0, all the slave machines execute that command. However,
no slave machine responds.
Note) There is a restriction on the number of data units of message that can be sent at a time.
(That this device can receive). (See section 8-4.)
