5 ASSIGNMENT OF I/O NUMBERS
5.5.2 Remote station I/O number
It is possible to allocate High Performance model QCPU device input (X) and output
(Y) to remote station I/O modules and intelligent function modules and control the
modules in the MELSECNET/H remote network, the CC-Link and other remote I/O
systems.

When using High Performance model QCPU device input (X) and output (Y) in remote
stations, I/O numbers that succeed the numbers used by the main base unit and
extension base units' I/O modules and intelligent function modules will be allocated.
For example, if X/Y0 to X/Y3FF are being used by the main base unit and extension
base units' I/O modules and intelligent function modules, then numbers above X/Y400
can be used by the remote station.
However, the I/O numbers for remote stations should be set in consideration of
additions to the main base unit and extension base units' I/O modules and intelligent
function modules.
For example, if 1024 points from X/Y0 to X/Y3FF are being used by the main base unit
and extension base units, and 256 points from X/Y400 to X/Y4FF are to be held back
for use with future additions, then the situation shown in the diagram below is to be
observed.

POINT
If network parameter setting is not made in the CC-Link system, 2048 points in the
range from X/Y1000 to X/Y17FF are assigned to the master local module of the
CC-Link having the lowest number.
REMARK
There is restriction on the order of allocating I/O numbers for MELSECNET/H
remote I/O networks, CC-Link or other networks.
