Allocations for the CPU Unit
Section 7-3
General I/O Area Range Setting (with PORT_A)
Explanation
• Area type specification (word m+74)
Specifies in hexadecimal the area to transfer between the CPU Unit and
the MC Unit.
0000: System variables
0001: Global general variables
0002: Input variables
0003: Output variables
0004: Position data
0005: Reserved
0006: Task variable 1
0007: Task variable 2
0008: Task variable 3
0009: Task variable 4
000A: Task variable 5
000B: Task variable 6
000C: Task variable 7
000D: Task variable 8
Other: Reserved
• First address (word m+75)
Specifies in hexadecimal the first word to be transferred in the area speci-
fied for the Area Type. Address specifications are as follows:
System variables 0000-07FF
Global general variables 0000-1FFF
Input variables 0000-0FFF
Output variables 0000-0FFF
Position data 0000-27FF (“0000” and “27FF”
correspond to xxxx in PLxxxx.)
Task variables 0000-007F
The settings for PORT_B to PORT_H are the same (m+76 to m+89).
Setting example
The following settings are used to transfer 10 words (0A Hex words) of data
from EM 20000 (4E20 Hex) in the EM Area of the PLC to position data
PL0000 to PL0004 in the MC Unit for custom I/O area A.
• Bit 08 of parameter P00004 is set to 1.

m+74 PORT_A transfer area type at MC Unit When the power is turned ON, or when
MC Unit is restarted
m+75 PORT_A transfer first address at MC Unit
Data configuration Setting range
