The clock data is not factory-set.
The clock data is used by the CPU module system and intelligent function
modules for error history, etc.
When using the CPU module for the first time, be sure to set the precise time.
If part of the clock data is corrected, all data must be written to the CPU module
again.
Write new clock data within the range given in (3) of this section.
If impossible time data is written to the CPU module, normal clock operation
cannot be performed.
However, if the data is impossible as time, an error will not occur when it is within
the range given in (3) of this section.
