11.5 When Battery Has Gone Flat during Storage of a programmable

When the programmable controller is to be used after being stored for some period of time
and the battery has gone flat during storage, the memories in the CPU module may be
corrupted.
Hence, before resuming operation, always format the memories using GX Developer.
After formatting the memories, write the memory contents backed up prior to storage to
each memory.
The relationships between battery and battery-backed memories are shown in Table11.6.
