Allocations for the CPU Unit
Section 7-3
03: DM area (custom address)
Specifies DM area of PLC starting from the specified first address
(m+3).
04: EM area (custom word)
Specifies EM area of PLC starting from the specified first address
(m+3).
When EM area (04) is specified for the operation data area in area type
specification (word m+2), EM area is fixed at Bank No.0.
Note Do not set the bank No. of the file memory on PLC. Specifying EM area of the
file memory bank No. causes the alarm [0044h: CPU memory error].
When mounting several MC Units on the same PLC, make sure that operation
data areas do not overlap. Since MC Units do not detect the error even if cus-
tom data areas of different Units are overlapping in PLC, a malfunction may
result.
For details on bank and file memory for the EM Area, refer to the
SYSMAC
CS Series Programmable Controllers Operation Manual (W339) or the SYS-
MAC CJ Series Programmable Controllers Operation Manual (W393).
• First address (word m+3)
When CIO (0001), WR (0002), DM (0003), or EM area (0004) is specified
for the operation data area in the area type specification (word m+2), the
first address is to be specified.
Set the first address in hexadecimal (Hex). The setting ranges are as fol-
lows:
CIO area: 0000 to 177F Hex (0 to 6015)
WR area: 0000 to 017F Hex (0 to 383)
DM area: 0000 to 7F7F Hex (0 to 32639)
EM area: 0000 to 7F7F Hex (0 to 32639)
When “Does not use the custom data area (0000)” is specified in the area
type specification (word m+2), this setting is not necessary.
Setting example
The custom data area is allocated, as shown below, starting from word
7530Hex (30000) of DM area in PLC.
Note Custom data area is allocated for 32 axes starting from the specified first
address regardless of the setting of the axis parameter [P1AA01: Physical
axis setting].
However, in the addresses corresponding to the axes that are set to “Not
used” in the axis parameter [P1AA01: Physical axis setting], data is not trans-
ferred between CPU Unit and MC Unit.
