A01 MULTI CPU ERROR 3015
Details
- In a multiple CPU system, the parameter settings are different between the modules.
Remedy
- Read the error details using a programming tool, check and correct the details of the parameter that
corresponds to the read value (parameter No. or CPU No.), as well as the parameter of the target
module.
A01 MULTI CPU ERROR 3100
Details
- The number of actually installed modules is different from that designated in the number of modules
setting parameter of MELSECNET/H.
- The head I/O number of actually installed modules is different from that designated in the network
parameter of MELSECNET/H.
- Some data in the parameters cannot be handled.
- The station type of MELSECNET/H has been changed while the power is ON.
(Reset and restart is required to change the station type.)
Remedy
- Check the network parameters and actual mounting status, and if they differ, make them matched.
If any network parameter has been corrected, write it to the CPU module.
- Check the extension base unit stage No. setting.
- 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 the
connection status.
- If the error occurs after the above checks, the possible cause is a hardware fault. Contact your local
service center.
Details
- In a multiple CPU system, the MELSECNET/H under control of another CPU is specified as the head
I/O number in the network setting parameter of the MELSECNET/H.
Remedy
- Delete the MELSECNET/H network parameter of the MELSECNET/H under control of another CPU.
- Change the setting to the head I/O number of the MELSECNET/H under control of the host CPU.
Details
- The network parameters of the MELSECNET/H operating as a normal station was changed to the
control station, or the network parameter of the MELSECNET/H operating as a control station was
changed to a normal station.
(The network parameter is updated on the module side by resetting.)
Remedy
- Reset the CPU module.
