* 2: MELSECNET/H remote I/O stations have a limit for the maximum number of parameters that can
be set with GX Configurator as intelligent function modules.
•The maximum number of parameter settings for initialization settings: 512
•The maximum number of parameter settings for automatic refresh settings: 256

Modules for the expanded system are mounted
to MELSECNET/H remote I/O station.
[Restrictions on Mounting Modules on Remote I/O
Stations]
• FROM/TO instructions and intelligent function
module devices (U \G ) are inapplicable. Use
REMFR/REMTO for accessing. Or, in GX
Configurator, configure the settings for intelligent
function modules on remote I/O stations.

• The following modules cannot be mounted to
remote I/O stations: CC-Link IE Controller Network
module, MELSECNET/H module, interrupt module,
Web server module, MES interface module,
PROFIBUS-DP master module, PROFIBUS-DP
slave module, PROFIBUS-DP interface module,
DeviceNet master module, DeviceNet slave
module, and AS-i master module.
• For Ethernet modules, dedicated instructions,
interrupt pointers, e-mail function, communication
by the fixed buffer, FTP server function, web server
function is not usable.
For intelligent function modules other than the above,
dedicated instructions and interrupt pointers are not
usable.
