Appendix 7.10 Multi CPU Errors (A)
A01 MULTI CPU ERROR 2100
Details
- In the I/O assignment setting of PLC parameter, intelligent function module was allocated
to an I/O module or vice versa.
- In the I/O assignment setting of PLC parameter, a module other than CPU (or nothing)
was allocated to the location of a CPU module or vice versa.
- In the I/O assignment setting of the PLC parameter, general switch setting was made to
the module that has no general switch setting.
- In the I/O assignment setting of the PLC parameter dialog box, the number of points
assigned to the intelligent function module is less than the number of points of the
mounted module.
Remedy
- Make the PLC parameter I/O assignment setting again so it is consistent with the actual
status of the intelligent function module and the CPU module.
- Delete the switch setting in the I/O assignment setting of the PLC parameter.
A01 MULTI CPU ERROR 2103
Details
- 2 or more interrupt module, QI60, where interrupt pointer setting has not been made are
mounted.
Remedy
- Reduce the QI60 modules to one.
- Make interrupt pointer setting to the second QI60 module and later.
A01 MULTI CPU ERROR 2106
Details
- 5 or more MELSECNET/H modules have been installed.
- 5 or more Ethernet modules have been installed.
- The same network Nos. or station Nos. exist in the MELSECNET/10 network system.
Remedy
- Reduce the number of MELSECNET/H modules to 4 or less.
- Reduce the number of Ethernet modules to 4 or less.
- Check the network Nos. and station Nos.
A01 MULTI CPU ERROR 2107
Details
- The start X/Y set in the PLC parameter’s I/O assignment settings is overlapped with the
one for another module.
Remedy
- Make the PLC parameter’s I/O assignment setting again so it is consistent with the actual
status of the intelligent function module.
