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 normally.
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 mounted
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 corresponds to
the common information is stored.)
Remedy
- The CPU module is experiencing a hardware fault.
Contact your local service center.
