A01 MULTI CPU ERROR 2011
Details
- The QA*B,QA1S*B was used as the base unit.
Remedy
- Do not use the QA*B,QA1S*B as the base unit.
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 as-
signed 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 sta-
tus 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.
A01 MULTI CPU ERROR 2110
Details
- The location designated by the FROM/TO instruction set is not the intelligent function mod-
ule.
- The module that does not include buffer memory has been specified by the FROM/TO in-
struction.
- The intelligent function module being accessed is faulty.
- Station not loaded was specified using the instruction whose target was the CPU shared
memory.
Remedy
- Read the individual information of the error using a programming tool, check the FROM/TO
instruction that corresponds to that numerical value (program error location), and correct
when necessary.
- The intelligent function module that was accessed is experiencing a hardware fault. Contact
your local service center.
A01 MULTI CPU ERROR 2111
Details
- The location designated by a link direct device (J* \ *) is not a network module.
- The I/O module (intelligent function module) was nearly removed, completely removed, or
mounted during running.
Remedy
- Read the individual information of the error using a programming tool, check the FROM/TO
instruction that corresponds to that numerical value (program error location), and correct
when necessary.
- The intelligent function module that was accessed is experiencing a hardware fault. Contact
your local service center.
A01 MULTI CPU ERROR 2112
Details
- The module other than intelligent function module is specified by the intelligent function mod-
ule/special function module dedicated instruction. Or, it is not the corresponding intelligent
function module.
- There is no network No. specified by the network dedicated instruction. Or the relay target
network does not exist.
Remedy
- Read the individual information of the error using a programming tool and check the special
function module dedicated instruction (network instruction) that corresponds to the value
(program error part) to make modification.
