Inner Board (D32000 to D32099)
The Inner Board is allocated 100 words. Refer to the Board’s Operation Man-
ual for details on the function of these words.
CPU Units only.
The EM Area is divided into 13 banks (0 to C) that each contain 32,768 words.
EM Area addresses range from E0_00000 to EC_32767. This data area is
used for general data storage and manipulation and is accessible only by
word.
Data in the EM 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 EM 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 EM Area cannot be force-set or force-reset.
There are two ways to specify an EM address: the bank and address can be
specified at the same time or an address in the current bank can be specified
(after changing the current bank, if necessary). In general, we recommend
specifying the bank and address simultaneously.
1. Bank and Address Specification
2. Current Bank Address Specification
Words in the EM Area can be indirectly addressed in two ways: binary-mode
and BCD-mode.
Binary-mode Addressing (@E)
When a “@” character is input before a EM address, the content of that EM
word is treated as binary and the instruction will operate on the EM word in
the same bank at that binary address. All of the words in the same EM bank
(E00000 to E32767) can be indirectly addressed with hexadecimal values
With this method, the bank number is specified just before the EM address.
For example, E2_00010 specifies EM address 00010 in bank 2.
With this method, just the EM address is specified. For example, E00010
specifies EM address 00010 in the current bank. (The current bank must
be changed with EMBC(281) to access data in another bank. A301 con-
tains the current EM bank number.)
The current bank will be reset to 0 when the operating mode is changed
from PROGRAM mode to RUN/MONITOR mode, unless the IOM Hold Bit
(A50012) is ON. The current bank is not changed as the program proceeds
through cyclic tasks.
