■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
Offset/gain setting mode (offset specification)
Offset/gain setting mode (gain specification)
■Enabling the setting
Turn off and on 'Channel change request' (YB).
■Default value
The default value is Disable (0) for all channels.
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.
