!Caution Do not allow the bank of the EM Area with the number specified for allocation
164
The bank number (0 to 12) of the EM bank allocated to the HMI data area is
set with ITEM050 of the System Common Block (block model 000.)
• System Common Block
EM area words 00000 to 00019 are allocated to send data.
EM area words 15000 to 15019 are allocated to receive data.
• Control/Operation Block: block addresses 001 to 500
EM area words 00020 to 10019 are allocated to send data.
EM area words 15020 to 25019 are allocated to receive data.
• External Control Block: block addresses 601 to 632
EM area words 12020 to 12659 are allocated to send data.
EM area words 27020 to 27659 are allocated to receive data.
Note (a) Even if there are unused block addresses, the blocks and ad-
dresses are not shifted. The block addresses always retain the
same structure.
(b) A total of 20 words is allocated to each function block as shown
below. The first 18 words (through the +17 words) are allocated
to analog data. The words +18 and +19 from the beginning words
are allocated as bit data.

Units. The block allocated for the HMI is specified in ITEM 050 (EM Area Bank
Allocated for HMI Memory = 0 to 12) of the System Common block (Block
Model 000). If areas overlap, the system may operate in an unexpected man-
ner, which may result in injury.
