Offset/gain setting mode (range specification) [Q compatible mode]
The output range can be changed in the offset/gain setting when the Q compatible mode function is used.
The output range is changed to the set one by 'Channel change request' (YB).
The setting written in 'Offset/gain setting mode (range specification)' (Un\G25) is applied to all the channels.

Offset/gain setting mode (range specification)
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.
 Digital-Analog Converter Module User's Manual
CH1 Synchronization digital value
When the inter-module synchronization function is enabled, the D/A conversion is performed to the digital value set in this
area in the inter-module synchronization cycle, and the value is output in the analog format in the next inter-module
synchronization cycle.
Output range setting
0: 4 to 20mA
1: 0 to 20mA
2: 1 to 5V
3: 0 to 5V
4: -10 to 10V
E: User range setting (voltage)
F: User range setting (current)
*1 The available setting range and practical range of when the scaling function is enabled differ depending on the setting of the scaling
upper limit value and scaling lower limit value.
When a value out of the available setting range is written, the D/A conversion is performed with the upper or lower limit value
of the available setting range. A check code is stored in 'CH1 Setting value check code' (Un\G400) and a digital value setting
range error (error code: 191H) is stored in 'Latest error code' (Un\G0).
