A01 MULTI CPU ERROR 3104
Details
- The Ethernet and MELSECNET/H use the same network number.
- The network number, station number or group number set in the network parameter is out
of range.
- The specified I/O No. is outside the range of the used CPU module.
- The Ethernet-specific parameter setting is 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 3105
Details
- Though the number of CC-Link modules set in the network parameters is one or more, the
number of actually mounted modules is zero.
- The head I/O number in the common parameters is different from that of the actually
mounted module.
- The station type of the CC-Link module count setting parameters is different from that of
the actually mounted station.
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 CC-Link module under control of another station is
specified as the head I/O number of the CC-Link network parameter.
Remedy
- Delete the CC-Link network parameter of the Q series CC-Link module under control of
another station.
- Change the setting to the head I/O number of the Q series CC-Link module under control
of the host station.
A01 MULTI CPU ERROR 3106
Details
- The CC-Link link refresh range exceeded the file register capacity.
Remedy
- Change the file register file for the one refresh-enabled in the whole range.
Details
- The network refresh parameter for CC-Link is out of range.
Remedy
- Check the parameter setting.
A01 MULTI CPU ERROR 3107
Details
- The CC-Link parameter setting is incorrect.
- The set mode is not allowed for the version of the mounted CC-Link module.
Remedy
- Check the parameter setting.
