4.1.2 Module Speed
The module uses one input word which is consistently transferred via the bus.
Here the momentary actual speed is output in mm/ms.

4.1.3 Module Error Display
The module uses 1 input byte, which is coded bit by bit. Over the input byte the error
message of the laser will transfer and is reset, if the error were recovered, or is no
more present.

Intensity
Bit 0 in the input byte
The bit is set, if an intensity value of smaller 8% is
present, or the laser beam is interrupted and leads to the
error value output.
Temperature
Bit 1 in the input byte
The bit is set, if the device temperature is outside of the
range from 0 - 50 °C. A low range deviation has still no
influence on the measurement and is therefore to be
regarded as a warning.
Hardware
Bit 2 in the input byte The bit is set, if an internal hardware error were noticed
and leads to the error value output.
Laser diode switched off
Bit 3 in the input byte
The bit is set, if the laser diode was switched off over the
bus, or the switching input. Serves only for information
purposes.
Warning bit Intensity
Bit 4 in the input byte
The bit is set, if an intensity value of smaller 12% were
determined and means that the measuring system optics,
or the reflecting foil is to be cleaned. However, the device
operates error-freely furthermore.
Warning bit Speed
Bit 5 in the input byte
The bit is set if the speed, adjusted in the PC program
OMSConfiguration Tool, is exceeded. About the default
setting the speed-check is switched off. A configurability
over the bus is not possible.
Warning bit Plausibility
Bit 6 in the input byte
The bit is set if the plausibility of the measured value
cannot be guaranteed. E.g. this is the case at a position
skip if a second reflection foil is held into the laser beam.
