5-5 Data Memory Area (D)
The DM area is used for general data storage and manipulation and is accessible only by word (16
bits).
These words retain their contents when the PLC is turned ON or the operating mode is switched
between PROGRAM mode and RUN or MONITOR mode.
Some words in the DM Area can be saved to the built-in Flash Memory using Auxiliary Area bits. These
words are specifically referred to as the backed up words in the DM Area.
The DM Area is automatically retained in the built-in non-volatile RAM even if the power supply is inter-
rupted.
• E-type CPU Units have DM Area addresses ranging from D0 to D4095.
Of these, D0 to D1499 can be backed up in backup memory (built-in Flash Memory).
• S-type CPU Units have DM Area addresses ranging from D0 to D8191.
Of these, D0 to D6999 can be backed up in backup memory (built-in Flash Memory).
• N-type CPU Units have DM Area addresses ranging from D0 to D16383.
Of these, D0 to D14999 can be backed up in backup memory (built-in Flash Memory).
