Appendix 7.10 Multi CPU Errors (A)
A01 MULTI CPU ERROR 3003
Details
- The number of devices set at the PLC parameter device settings exceeds the possible
CPU module range.
Remedy
- Read the detailed information of the error using a programming tool, check the parameter
items corresponding to those numerical values (parameter numbers), and correct when
necessary.
- If the error is still generated following the correction of the parameter settings, the possible
cause is the memory error of the CPU module's built-in RAM, program memory or the
memory card. Contact your local service center.
Details
- The automatic refresh range of the multiple CPU system exceeded the file register
capacity.
Remedy
- Change the file register file for the one refresh-enabled in the whole range.
A01 MULTI CPU ERROR 3004
Details
- The parameter file is incorrect.
Alternatively, the contents of the file are not parameters.
Remedy
- Check whether the parameter file version is ***QPA, and check the file contents to be sure
they are parameters.
A01 MULTI CPU ERROR 3012
Details
- Multiple CPU setting or control CPU setting differs from that of the reference CPU settings
in a multiple CPU system.
Remedy
- Match the multiple CPU setting or control CPU setting in the PLC parameter with that of
the reference CPU (CPU No.1) settings.
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.
