*If you use HWCONFIG to set values in CRs, once the set value is downloaded, the values can be retained in
the module; however if you use TO instruction to write data into CRs, the values CANNOT be retained, after
power failure or after transition of the CPU from STOP to RUN.
Note: The attribute of the CR must be W (write) to use TO instruction.
