* 1: MELSECNET/H network system 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.
*1
• The following modules cannot be mounted to remote
I/O stations: CC-Link IE Controller Network module,
MELSECNET/H network 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 interface 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.
<<First 5 digits of serial No. is "09012" or later>>

• The following modules cannot be mounted:
Interrupt module, CC-Link IE Controller Network
module, MELSECNET/H network module, Ethernet
interface module (function version: B or earlier), Web
server module (first 5 digits of serial No.: "09011" or
earlier), PROFIBUS-DP master module, PROFIBUS-
DP slave module, PROFIBUS-DP interface module,
DeviceNet master module, and DeviceNet slave
module.
• For intelligent function modules, dedicated
instructions and interrupt pointers are not usable.
