Corrective Action
• Check the network parameters and actual
mounting status, and if they differ, make them
matched. If any of the network parameters is
corrected, write it to the CPU module.
• Check the set number of extension base units.
• Check the connection status of the extension
base units and extension cables.
Check the connection of the GOT if it is bus-
connected to the main base unit or extension
base unit.
If an error occurs even after taking the above
*12
measures, the cause is a hardware failure.
(Please consult your local Mitsubishi
representative, explaining a detailed description
of the problem.)
• Set the mode switch of MELSECNET/H
*12
module within the range.
Change the file register file for the one that
enables entire range refresh.
Correct the type or station number of the
MELSECNET/H module in the network parameter
to meet the used system.
Set the refresh parameter within the range of
device setting.
