REMARKS
What is network type?
The network type is a parameter set for specifying the network where the network
module is used.
Set the network type of the network module in the Network parameter of GX
Developer.
There are the following network types.

MELSECNET/H mode
MELSECNET/H Extended
mode
MELSECNET/10 mode
Network to be connected
MELSECNET/10
PLC to PLC network
(MESLECNET/10 mode)
Set this mode when all CPUs within the network are QCPUs.
The maximum number of link points per station has been increased
compared with the MELSECNET/H mode.
In excess of 2000 bytes, a maximum of 35840 bytes can be set.
Set this mode when the system uses many link points per station.
This mode is used to operate the network module on a
MELSECNET/10 network where the QnA/AnU exists.
