Multi CPU Errors (A)
I - 50
A01 MULTI CPU ERROR 1201
Details
- The hardware (logic) in the CPU module does not operate normally.
Remedy
- This suggests a CPU module hardware fault.
Contact your local service center.
A01 MULTI CPU ERROR 1202
Details
- The operation circuit for sequence processing in the CPU module does not operate normal-
ly.
Remedy
- This suggests a CPU module hardware fault.
Contact your local service center.
A01 MULTI CPU ERROR 1300
Details
- There is an output module with a blown fuse.
Remedy
- Check FUSE. LED of the output modules and replace the module whose LED is lit.
- The module with a blown fuse can also be identified using a programming tool. Check the
special registers SD1300 to SD1331 to see if the bit corresponding to the module is "1".
- When a GOT is bus-connected to the base unit, check the connection status of the extension
cable and the earth status of the GOT.
A01 MULTI CPU ERROR 1310
Details
- An interruption has occurred although there is no interrupt module.
Remedy
- Any of the mounted modules is experiencing a hardware fault. Therefore, check the mount-
ed modules and change the faulty module.
Contact your local service center.
A01 MULTI CPU ERROR 1311
Details
- An interrupt request from other than the interrupt module was detected.
Remedy
- Take action so that an interrupt will not be issued from other than the interrupt module.
Details
- An interrupt request from the module where interrupt pointer setting has not been made in
the PLC parameter dialog box was detected.
Remedy
- Correct the interrupt pointer setting in the PLC system setting of the PLC parameter dialog
box.
- Take measures so that an interrupt is not issued from the module where the interrupt pointer
setting in the PLC system setting of the PLC parameter dialog box has not been made.
- Correct the interrupt setting of the network parameter.
- Correct the interrupt setting of the intelligent function module buffer memory.
- Correct the basic program of the QD51.
A01 MULTI CPU ERROR 1401
Details
- There was no response from the intelligent function module in the initial communication.
- The size of the buffer memory of the intelligent function module is invalid.
- There was no response from the intelligent function module.
(When error is generated, the head I/O number of the special function module that corre-
sponds to the common information is stored.)
Remedy
- The CPU module is experiencing a hardware fault.
Contact your local service center.
A01 MULTI CPU ERROR 1402
Details
- The intelligent function module was accessed in the program, but there was no response.
Remedy
- The CPU module is experiencing a hardware fault.
Contact your local service center.
A01 MULTI CPU ERROR 1403
Details
- There was no response from the intelligent function module when the END instruction is ex-
ecuted.
- An error is detected at the intelligent function module.
- The I/O module (intelligent function module) is nearly removed, completely removed, or
mounted during running.
Remedy
- The CPU module, base unit and/or the intelligent function module that was accessed is ex-
periencing a hardware fault. Contact your local service center.
A01 MULTI CPU ERROR 1411
Details
- When performing a parameter I/O allocation the intelligent function module could not be ac-
cessed during initial communications.
(On error occurring, the head I/O number of the corresponding intelligent function module is
stored in the common information.)
Remedy
- Reset and restart the CPU module.
If the same error is displayed again, the intelligent function module, CPU module or base
unit is faulty.
Contact your local service center.
