3.9 List of Alarm Code
Description and cause
Hardware error of analog ADP was detected.
The power is not supplied normally.
Read error or damaged EEPROM.
There is some offset/gain data defect or setting
defect in EEPROM.
Communication error occurred between the
analog ADP and the PLC.
Description and cause
There is no error.
Warning output alarm (upper limit) has occurred
in the CH.
Warning output alarm (lower limit) has occurred
in the CH.
The saved offset/gain output range is different
from the currently set output range.
The range was changed during offset/gain
writing or offset/gain initialization.
Offset/gain initialization was executed during
offset/gain writing.
Offset/gain writing was executed during offset/
gain initialization.
Offset/gain writing, offset/gain reading or offset/
gain initialization was executed while the analog
ADP memory error (Error code: 3082H) was
detected.
Or offset reading was executed while the analog
ADP memory error (Error code: 3083H) was
detected.
Special relays/registers for analog are changed
while conversion is enabled.
Action
After resetting the CPU unit, carry out RUN. If
the same error is displayed again, there is a
possibility of hardware error of the analog ADP.
Consult the nearest Mitsubishi Electric
representative.
Confirm if the power is supplied properly.
After resetting the CPU unit, carry out RUN. If
the same error is displayed again, there is a
possibility damaged EEPROM. Consult the
nearest Mitsubishi Electric representative.
Reset the data by offset/gain settings.
Confirm if ADP is connected properly to the
PLC. If not improved, consult the nearest
Mitsubishi Electric representative.
Action
When the CH digital operation value returns
from the warning output range, the alarm code
automatically changes to "0: Normal".
Change the currently set output range to the
output range selected when the offset/gain was
written, and then read the offset/gain.
Wait until offset/gain writing or offset/gain
initialization is finished, and then change the
range.
Wait until offset/gain writing is finished, and then
initialize the offset/gain.
Wait until offset/gain initialization is finished,
and then write the offset/gain.
Reset the CPU module.
Change the setting of special relays/registers
while conversion is disabled.
