The DM Area contains 32,768 words with addresses ranging from D0 to
D32767. This data area is used for general data storage and manipulation
and is accessible only by word.
Data in the DM Area is retained when the PLC’s power is cycled or the PLC’s
operating mode is changed from PROGRAM mode to RUN/MONITOR mode
or vice-versa.
Although bits in the DM Area cannot be accessed directly, the status of these
bits can be accessed with the BIT TEST instructions, TST(350) and
TSTN(351).
