make offset/gain setting in the device test of GX Developer.
To switch modes, set a value to Mode switching setting (buffer memory address
158, 159: Un\G158, Un\G159), and turn on and off Operating condition setting
request (Y9).
Note that if module control is resumed without offset/gain setting being made,
operation will be performed with the default values.
