• To apply the offset/gain values set in one module to the other modules in the same system:
Ex.
When the offset/gain values in module No.1 are applied to modules No.2 to No.4
Saving and restoring by dedicated instructions
Use the dedicated instruction G(P).OGLOAD to temporarily save the offset/gain values of the source temperature input
module to the internal device of the CPU module, then use G(P).OGSTOR to write the values to the destination temperature
input module.
Prevent the saved offset/gain setting data from being deleted, by one of the following methods before replacing the modules:
• Use latch settings for the internal device of the destination module.
• Save the data onto an SD memory card. (For data write: Use the SP.FWRITE instruction. For data read: Use the
SP.FREAD instruction.)
• Record the saved data.
For use of dedicated instructions, refer to the following.
