• When the station number of the
MELSECNET/H module is 0, the
inter-PLC network parameter setting
has been made.
• When the station number of the
MELSECNET/H module is other
than 0, the remote master parameter
setting has been made.
Correct the type or station number of
the MELSECNET/H module in the
network parameter to meet the used
system.
• The network No. specified by a
network parameter is different from
that of the actually mounted
network.
• The head I/O No. specified by a
network parameter is different from
that of the actually mounted I/O unit.
• The network class specified by a
network parameter is different from
that of the actually mounted
network.
• The network refresh parameter of
the MELSECNET/H, MELSECNET/
10 is out of the specified area.
• Check the network parameters and
mounting status, and if they differ,
match the network parameters and
mounting status.
If any network parameter has been
corrected, write it to the CPU
module.
• Confirm the setting of the number of
extension stages of the extension
base units.
• Check the connection status of the
extension base units and extension
cables.
When the GOT is bus-connected to
the main base unit and extension
base units, also check their
connection status.
If the error occurs after the above
checks, the cause is a hardware fault.
(Contact your local Mitsubishi
representative, explaining a detailed
description of the problem.)
A multi-remote I/O network was
configured using a module that does
not support the MELSECNET/H multi-
remote I/O network.
Use a module that supports the
MELSECNET/H multi-remote I/O
network.
