4.2 I/O Number Assignment
4.2.1 Concept of I/O number assignment
(2) I/O assignment on a remote I/O stations
CPU module device input (X) and output (Y) can be assigned to I/O modules and intelligent function modules,
which allows to control the modules in the remote I/O system such as MELSECNET/H remote I/O network and
CC-Link.
Also, inputs (X) and outputs (Y) can be used for the refresh target (devices on the CPU module side) of the
MELSECNET/H module link I/O (LX and LY).
(a) I/O numbers available on remote I/O stations
When the input (X) and output (Y) of the CPU module are used for the I/O numbers in the remote
station, assign the I/O numbers later than those used for the I/O modules and intelligent function
modules on the CPU module side.
When X/Y0 to X/Y3FF (1024 points) are used for the I/O modules and intelligent function modules
on the CPU module side, X/Y400 and later can be used in the remote stations.
