When using CX-Process Tool version 4.0 or higher, a list can be displayed show-
ing the areas of the CPU Unit's I/O memory that are being used by the Loop Con-
troller. The list is displayed for each area type in address order. The following
areas can be displayed and the status can be confirmed by the color of the ad-
dress cell.
• When HMI I/F Area is allocated:
Send Area (Loop Controller → CPU): Blue
Receive Area (CPU → Loop Controller): Pink
• When analog or contact signals are allocated in the addresses of the User Link
Table: Green
• When analog or contact signals are allocated in the field terminal block:
Orange
• When program pattern data is allocated in Segment Program 3 (Block Model
158): Dark green
Note 1. For User Link Table contacts, the I/O memory address in which the contact
signal is allocated is displayed in color.
2. The following two types of overlapping can be confirmed when checking
whether the same I/O memory address has been used more than once.
• When data has been written (sent) from the Loop Controller to the same
I/O memory address in the CPU Unit: The corresponding cell will be dis-
played in red to indicate an overlap warning.
• When data has been read (received) to the Loop Controller from the same
I/O memory address in the CPU Unit, or when data has been read (re-
ceived) from and written (sent) to the same I/O memory address in the
CPU Unit: The corresponding cell will be displayed in aqua to indicate an
overlap in the receive area.

This function simplifies management of the CPU Unit memory by enabling con-
firmation of which areas in the CPU Unit's I/O memory are being used by the
Loop Controller.

Displays whether the tag is being used in
the HMI interface data area, the User Link
Table, or a Field Block Terminal.
Also displays whether any address is being
used more than once.
