Data Memory (DM) Area
Forcing Bit Status
Indirect Addressing
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).
Bits in the DM Area cannot be force-set or force-reset.
Words in the DM Area can be indirectly addressed in two ways: binary-mode
and BCD-mode.
Binary-mode Addressing (@D)
When a “@” character is input before a DM address, the content of that DM
word is treated as binary and the instruction will operate on the DM word at
that binary address. The entire DM Area (D00000 to D32767) can be indi-
rectly addressed with hexadecimal values 0000 to 7FFF.
BCD-mode Addressing (*D)
When a “*” character is input before a DM address, the content of that DM
word is treated as BCD and the instruction will operate on the DM word at that
BCD address. Only part of the DM Area (D00000 to D09999) can be indirectly
addressed with BCD values 0000 to 9999.
