CX-Programmer for CP1E
IBM PC/AT or equivalent
Precautions for Correct Use Precautions for Correct Use
For CP1E CPU Units, the following I/O memory area will be unstable after a power interruption.
• DM Area (D) (excluding words backed up to the EEPROM using the DM function)
• Holding Area (H)
• Counter Present Values and Completion Flags (C)
• Auxiliary Area related to clock functions(A)
Mount the CP1W-BAT01 Battery (sold separately) to an N-type CPU Unit if data in the
above areas need to be retained after a power interruption. A Battery cannot be mounted to
an E-type CPU Unit.
