When a module-specific backup parameter is not used
When not using a module-specific backup parameter, save and restore offset/gain values with the following methods.
• Saving and restoring by dedicated instructions
• Saving and restoring by reading from and writing to the buffer memory
Using the above methods, restoration of offset/gain values to a new module or application of offset/gain values set in one
module to the other modules in the same system is also possible.
• To restore offset/gain values onto a new replaced module:
1.
Save the offset/gain values.
2.
Power off the programmable controller and replace a
temperature input module.
3.
Restore the offset/gain values.
