Description
Corrective measures
Lens temper-
ature too high
W#16#5019 25 -- The temperature of the lens
is outside the valid range.
This can lead to incorrect
read results, shortened
service life or destruction of
the reader.
Reduce the ambient tempera-
ture, e.g. by air circulation, or
dissipate the heat and ensure
that the ambient temperature is
within the permissible range.
Sensor tem-
perature too
high
W#16#501A 26 -- The temperature of the
sensor is outside the per-
missible range. The proba-
ble cause is an excessively
high ambient temperature.
Reduce the ambient tempera-
ture, e.g. by air circulation, or
dissipate the heat and ensure
that the ambient temperature is
within the permissible range.
No message -- -- E4FE84 Error in last command se-
quence
Note:
No diagnostic interrupt is
sent to the I/O controller.
May occur if triggering is too
fast. The Ident profile can only
process one command at a time
before a new command can be
executed.
Self-acknowledging connection errors
The following connection errors are self-acknowledging:
● Error "TCP communication"
● Error "Archiving/MMI communication"
● Error "PROFINET IO connection error"
● Error "PROFINET IO controller status 'Stop'"
As soon as the connection is re-established after an interruption, the optical reader exits the
error state. The optical reader returns to the mode prior to the occurrence of the error, for
example, back to processing mode.
The occurrence of these errors and their automatic acknowledgment are stored in the
diagnostic data records. Stored error messages are not overwritten by newer errors.
If there are error entries, a corresponding note appears in the WBM during processing mode
("Start") in the "Program > Info statistics" area.
Note
PROFINET IO error / OB 86 not programmed
Note that the
occurrence of a PROFINET IO error in a SIMATIC S7 controller causes OB 86
(rack failure OB) to be called. If you have not programmed OB 86, the controller goes to the
"STOP" state.
