Process Input Data - Error Status:
About the status byte error messages of the measuring system are transferred bit-wise. Warnings are
always reset automatically if the error was removed or is no more present, with the exception of the
warning bit
Speed
. By default error messages are reset automatically if the error is no more present,
see chapter
“Index 0x0066: Failure Autoquit” on page 65.
If the automatic error acknowledgement is disabled the error messages
Intensity
,
Temperature
and
Hardware
, as well as the warning bit
Speed
can be acknowledged by means of bit 2
2
of the
c
ontrol byte or the optional function “Reset Failure Value” of the external switching input, see chapter
“Index 0x006E: Ext. Input Function”, on page 73.
Definition:
“1” = active.
Standard value: 0x00 = no error.
Bit
Function
Description
0
Intensity
The bit is set, if an intensity value of < 8% is present, or the laser beam
is interrupted.
The bit is also set, if the laser diode was switched off.
1
Temperature
The bit is set, if the device temperature is outside the permissible
working temperature. A small range deviation has no influence on the
measured value and should therefore be regarded as a warning. The
limit value can be changed via TRWinProg.
2
Hardware
The bit is set, if an internal hardware error is detected and leads to the
failure value output. Optically, this error is displayed via the device
status LED = red.
3
Laser diode
switched off
The bit is set, if the laser diode was switched off over the IO-Link
interface, or the optional switching input. Serves only for information
purposes.
4
Warning bit
Intensity
The bit is set, if the permissible intensity value has been fallen below.
The standard limit is 12% and can be changed via TRWinProg.
The bit is also set, if the laser diode was switched off.
5
Warning bit
Speed
The bit is set, if the adjusted speed is exceeded. About the default
setting the speed-check is switched off. Configurability see chapter
“Index 0x0054: Max. Speed” on page 70.
6
Warning bit
Plausibility
measuring value
The bit is set, if the plausibility of the measured value cannot be
guaranteed. E.g. this is the case at a position jump if a second reflection
foil is held into the laser beam.
7
Warning bit
Measuring range
The bit is set if a measurement outside the range of 0.1 to 25 m is
performed.
Error causes and remedies are determined in chapter “Other faults”, see page 87.
