4.2 Concept of I/O Number Assignment
4.2.1 I/O numbers of base unit
The CPU module assigns I/O numbers when the programmable controller is powered ON
or the reset operation of the CPU module is performed.
I/O numbers are assigned automatically from the right side of the CPU module of the main
base unit.
When two CC-Link Safety master modules and one CC-Link IE controller module are
mounted on the main base unit, the I/O numbers are assigned as shown in Figure 4.1.
For the empty slot where no CC-Link Safety master module or CC-Link IE controller
network module is mounted on the main base unit, the points set on the PLC system
setting tab of PLC parameter in GX Developer are assigned. (Default: 16 points)
Remark
The start I/O number can be changed for each slot on the I/O assignment setting tab
of PLC parameter in GX Developer.
4.2.2 I/O numbers of remote station
It is possible to assign input (X) and output (Y) of the CPU module to the remote station I/
O modules and control the modules in the CC-Link Safety.
(1) CPU module I/O numbers that can be used at remote stations
When two CC-Link Safety master modules and one CC-Link IE controller module are
mounted on the main base unit, the CPU module uses X/Y0 to X/Y5F.
When using CPU module input (X) and output (Y) for remote station I/O numbers, use
X/Y60 or later.
