MELSECNET/10 network modules and MELSECNET/H network modules
cannot be mixed.
• MELSECNET/H remote I/O modules cannot be connected to
MELSECNET/10 master modules.
• MELSECNET/10 remote I/O modules cannot be connected to
MELSECNET/H master modules.
When changing remote I/O modules, use MELSECNET/H for all network
modules.
The network number setting switches and condition setting switches for the
MELSECNET/10 network modules are not found on the MELSECNET/H
network module.
These settings must be made by the network parameters.
The network parameters for the remote master station require the corrections
shown in (2) above.
• The I/O allocation settings set by the network parameters of the
MELSECNET/10 remote I/O network master module is set by the remote I/O
module PLC parameters on the MELSECNET/H remote I/O network.
• When changing the intelligent function modules mounted to the remote I/O
station, there is a need to make switch settings using the remote I/O station
PLC parameters. For details, refer to the user's manual for the intelligent
function module being used.
