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
measures, the cause is a hardware failure.
Please consult your local Mitsubishi
representative.

• Delete the MELSECNET/H network
parameter of the MELSECNET/H under
control of another CPU.
• Change the setting to the start I/O number
of the MELSECNET/H under control of the
host CPU.
Reset the CPU module.
