5.3 Function code of an analogue setting value
5.3.1 Reading of an analogue setting value
[Function code: 03 (03H)]
Continuously analogue setting value (2 bytes: 16 bits) is read out only the designated number
from the designated No. The reading order is an upper class (H) 8 bits, the subordinate class (L) 8
bits.
5.3.2 Writing of an analogue setting value
[Function code: 06 (06H)]
Program the analogue setting value of the designated No to the designated value.
[Example] Reading of upper class “H” data and subordinate class “L” data of
calibration curve coefficient a0 of slave 1.
(Reading out 2 data of reference No 40022 to 40023)
Reference No 40022 40023

*1: Start No (Relative No) is "Reference No-40001".
*2: The data number is the byte number of data. (It is not the demand number).
*3: The reading order is an upper class (H) 8 bits, the subordinate class (L) 8 bits.
*4: The reading order is the subordinate class (L) 8 bits, an upper class (H) 8 bits.

Same answer as a command message at the time of a normal answer.
[Example] Program the [Constituent 1: Calibration curve No] to “1”.
Program the [Analog setting value reference No 40001] to “1”.
