Offset/gain adjustment value specification
Set the adjustment amount of the analog output value in the offset/gain setting mode.
For the offset/gain setting, refer to the following.

■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
Offset/gain adjustment value specification
Offset/gain adjustment value specification (When
the Q compatible mode function is used)
■Setting range
The setting range is from -3000 to 3000.
Ex.
When the setting value is 1000
The analog output value is adjusted to approx. 0.31V (in voltage output) or approx. 0.35mA (in current output).
When the offset/gain setting is configured from the offset/gain setting window of an engineering tool, the
setting is performed properly on the window. Therefore, a program is not required to perform the setting.
To configure the offset/gain setting from a program, set the offset/gain setting mode (offset specification) and
offset/gain setting mode (gain specification). For details, refer to the following.

CH1 Offset/gain setting mode
Specify the channel where the offset/gain setting is adjusted.
• Offset/gain setting mode (offset specification): Channel to adjust the offset
• Offset/gain setting mode (gain specification): Channel to adjust the gain
Setting value
0
1
Multiple channels cannot be set at the same time. Set Disable (0) in Offset/gain setting mode (offset specification) or in Offset/
gain setting mode (gain specification).
When a value other than the above is set, Offset/gain setting channel range error (error code: 1E8H) occurs.
In the following cases, an offset/gain setting channel specification error (error code: 1E50H) occurs.
• When Setting channel (1) is set for both of Offset/gain setting mode (offset specification) and Offset/gain setting mode (gain
specification) of the same channel
• When Disable (0) is set for all channels
• When multiple channels are set at the same time

■Enabling the setting
Turn off and on 'Channel change request' (YB).
■Default value
The default value is Disable (0) for all channels.
