D/A converter modules
■Restoration of the user range setting
Setting the following item to "Enable" allows the module-specific backup parameter (offset/gain value) in the CPU module or
remote head module to be automatically restored upon module recognition. Thus, even without the use of dedicated
instructions or other means, a newly replaced D/A converter module operates with the same user range setting as that of the
old D/A converter module.
Setting the following item to "Disable" does not allow the offset/gain value to be automatically restored upon module
recognition. When replacing the module with a new D/A converter module where the offset/gain setting is already set up, set
the following item to "Disable" to perform online module change.
[Navigation window]  [Parameter]  Target module  [Module Parameter]  [Application setting]  [Online module
change]  [Auto restore of Offset/gain setting with the module change]
Replacing the module with a D/A converter module where the offset/gain setting is already set up results in
the mismatch of offset/gain values between the module-specific backup parameter of the CPU module or
remote head module and the user range. After the replacement, update the module-specific backup
parameter of the CPU module or remote head module. For the update method, refer to the User's Manual
(Application) for each module.
■Q compatible mode
A module in operation in Q compatible mode also allows online module change. The newly replaced D/A converter module
starts up in Q compatible mode.
■Operation mode
Online module change is permitted regardless of the mode set as the operation mode. After the replacement, the operation
starts up with the settings of module parameters written in the CPU module or remote head module.
Temperature input modules
■Restoration of the user range setting
Setting the following item to "Enable" allows the module-specific backup parameter (offset/gain value) in the CPU module or
remote head module to be automatically restored upon module recognition. Thus, even without the use of dedicated
instructions or other means, a newly replaced temperature input module operates with the same user range setting as that of
the old temperature input module.
Setting the following item to "Disable" does not allow the offset/gain value to be automatically restored upon module
recognition. When replacing the module with a new temperature input module where the offset/gain setting is already set up,
set the following item to "Disable" to perform online module change.
[Navigation window]  [Parameter]  Target module  [Module Parameter]  [Application setting]  [Online module
change]  [Auto restore of Offset/gain setting with the module change]
Replacing the module with a temperature input module where the offset/gain setting is already set up results
in the mismatch of offset/gain values between the module-specific backup parameter of the CPU module or
remote head module and the user range. After the replacement, update the module-specific backup
parameter of the CPU module or remote head module. For the update method, refer to the User's Manual
(Application) for each module.
■Q compatible mode
A module in operation in Q compatible mode also allows online module change. The newly replaced temperature input
module starts up in Q compatible mode.
■Operation mode
Both in normal mode and in offset/gain setting mode, online module change is permitted. After the replacement, the operation
starts up with the settings of module parameters written in the CPU module or remote head module.
