A01 MULTI CPU ERROR 3013
Details
Multiple CPU automatic refresh setting is any of the followings in a multiple CPU system.
- When a bit device is specified as a refresh device, a number other than a multiple of 16 is
specified for the refresh-starting device.
- The device specified is other than the one that may be specified.
- The number of send points is an odd number.
- The total number of transmission points is greater than the maximum number of refresh
points.
- The automatic refresh parameter was set for the CPU that does not support the automatic
refresh.
- The device to transmit is not set.
Remedy
Check the following in the multiple CPU automatic refresh parameters and make correction.
- Specify the device that may be specified for the refresh device.
- Set the number of send points to an even number.
- The total number of transmission points is within the maximum number of refresh points.
- Set the parameter to the CPU that supports the automatic refresh.
- Specify the device to transmit.
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 param-
eter that corresponds to the read value (parameter No. or CPU No.), as well as the param-
eter 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 an-
other 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.
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 spec-
ified 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.
