• 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 A/D converter module to
the internal device of the CPU, then use G(P).OGSTOR to write the values to the destination A/D converter 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. (To write data: use the SP.FWRITE instruction. To read data: use the SP.FREAD
instruction.)
• Store the saved data.
For use of dedicated instructions, refer to the following.
