4.1.1.2 Significance of the Status Information
Bit 0: Alarm
The alarm bit indicates whether an object lies within the measurement value range.
Bit0 = 0 → An object lies within the specified measuring range.
Bit0 = 1 → There is no object within the specified measuring range.
Bit 1: Switch bit
In the IO Link communication mode, the switch bit performs the function of a switching output.
Bit1 = 0 → There is no object within the the switching range.
Bit1 = 1 → An object lies within the switching range.
Bit 2: Quality
This bit provides information about the amount of light reflected by the object being measured (soiled lens
indicator).
Bit2 = 0 → The amount of reflected light exceeds the threshold (adequate signal strength).
Bit2 = 1 → The amount of reflected light lies below the threshold (weak signal strength).
Bit3: Not used
4.2 Parameters and Commands
Parameters and commands are either written to the device or read from it using SPDU (Service Protocol
Data Unit) indices. The read and write function is provided by the IO Link master. The user can write a value
to an index, or can have a value read from it.
4.2.1 Product Information
Some parameters contain product information such as the manufacturer’s name, the product name and
number, together with a user-specific sensor designation (refer to Table Fehler! Verweisquelle konnte nicht
gefunden werden., Table of General Information SPDUs).
4.2.2 Parameters
For a description of parameters, refer to Table 6.2, Table of Parameter SPDUs.
4.2.3 Commands
Commands are written to SPDU Index 0x02 (system commands). Refer to Table 6.3 Table of System Com-
mands.
4.2.4 Saving Modifications
If parameters have been modified by either directly writing to them or by a command (this also includes re-
setting to factory settings), the modifications must be permanently saved by means of Save parameters.
Failure to do this will result in the modifications being lost when the sensor is restarted. The sensor will then
use the most recently saved entries.
