411
Memory cassette is write-
protected. Check the
memory cassette.
The memory cassette installed in PLC CPU is in the state
protected with EPROM or E
2
PROM.
Confirm the memory cassette installed in PLC CPU.
412
Cannot read/write device
protected by keyword.
Remove keyword.
The key word is set in PLC CPU.
Cancel the key word.
420
E71 specification is
ASCII.
[ASCII code] is selected in [Ethernet operations] of the PLC
side setting.
Select [Binary code].
421
E71 is set as read-only.
Clear setting.
The Ethernet module on the PLC side is set in read-only.
Set the Ethernet module on the PLC side to write-enabled.
422
Not communicating
between CPU and E71.
Confirm CPU error.
PLC CPU error. Communication between PLC CPU and the
PLC side Ethernet module impossible.
Confirm whether there is error in PLC CPU by GX Developer
etc. (Confirm buffer memory)
423
Insufficient network table
information. Add station
no.
The station number set in the object, etc. does not exist in the
Ethernet setting.
1. Add the station number set in the object, etc. to the
Ethernet setting.
2. When station No. switching is used, check the settings of
the station No. switching device.
If the used station number is not set in the Ethernet setting,
add the station number.
If the station number does not exist in a system, review the
settings of the station No. switching device.
(Set the station number so that it becomes the same as the
station number of the PLC CPU side Ethernet module set
by the parameter of GX developer.)
424
Same sta. on GOT &
project data. Review
communication
parameter.
The station number set in the GOT's utility is the same as the
station number set by the GT Designer2 Ethernet setting (the
station number of the PLC side Ethernet module) or by the
project data.
Confirms the following contents so that the multiple station
numbers should not be the same.
1. Confirm the station number of GOT by the utility of GOT.
2. Confirm the station number set by the project data.
3. Confirm the station number set by the Ethernet setting.
(Set the station number so that it becomes the same as the
station number of the PLC CPU side Ethernet module set
by the parameter of GX developer.)
4. When station No. switching is used, check the settings of
the station No. switching device.
448
PLC cannot handle as
requested. Correct
devices.
The file register of QnACPU and the device beyond the
outside range of buffer memory was specified.
Correct the monitor device by setting file register of PLC CPU.
