(8) Parameter setting data register (offset address +6, +7)
When a value in the range from “30000” to “32767” (INT type) is input to the mode changeover register (offset address +4), bit
15 of the module status register (offset address +0) is set ON, and “parameter mode” is activated.
The set values of “operation parameter write” mode, “scaling parameter” mode or “offset/gain adjustment” mode are written in
this register.
1) When operation parameter setting mode is activated
Data is set in the locations shown below, and “operation parameter write mode flag” (bit 4 of the parameter type setting
register) is set ON.
* When using D300win, assign WORD type variables to these registers. If you access by the bit, assign a BOOL type variable
to each bit.

2) When scaling parameter setting mode is activated
For scaling, offset and gain values are set in the locations shown below.
* When using D300win, assign INT type variables to these registers.
<Scaling>
The analog output modules convert the digital values that are input to them by application program into analog values. The
operation to change the width (scale) of input digital values is referred to as “scaling”. The available range of scaling of these
modules is -25000 to 25000 (INT type). If a value that is out of this range is set, it will be limited to -25000 or 25000.
