A01 MULTI CPU ERROR 3101
Details
- The link refresh range exceeded the file register capacity.
Remedy
- Set either the larger capacity for file register or the narrower range for link refresh.
Details
- 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.
Remedy
- 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
service center.
A01 MULTI CPU ERROR 3102
Details
- The result after checking network parameters in the network module shows an error.
- The parameters specific to MELSECNET/H and MELSECNET/10 are not normal.
Remedy
- Correct and write the network parameters.
- If the error occurs after correction, it suggests a hardware fault. Contact your local service
center.
A01 MULTI CPU ERROR 3103
Details
- Although the number of modules has been set to 1 or greater number in the Ethernet
module count parameter setting, the number of actually mounted module is 0.
- The head I/O No. of the Ethernet network parameter differs from the I/O No. of the actually
mounted module.
Remedy
- Correct and write the network parameters.
- If the error occurs after correction, it suggests a hardware fault. Contact your local service
center.
Details
- In a multiple CPU system, the Q series Ethernet interface module under control of another
station is specified to the head I/O number of the Ethernet network parameter.
Remedy
- Delete the Ethernet network parameter of MELSECNET/H module under control of
another station.
- Change the setting to the head I/O number of the MELSECNET/H module under control of
the host station.
