IO-Link functions
This section is only relevant for sensors that
support IO-Link.
Sensors that support IO-Link feature an IO-Link
communication interface that allows direct access to
sensor values and parameters. An IO-Link master is
required for communication.
You can find the description files (IO-Link Device
Description – IODD) necessary for configuration as
well as further information at www.balluff.com .
Without an IO-Link master, IO-Link devices operate in the
SIO mode (Standard Input/Output) and behave like devices
with a conventional output. The settings made using
IO-Link are also effective in SIO mode.
6.1 Parameter objects
The parameter objects are described in the following.
6.1.1 System Command
Writing to this parameter allows you to activate various
system commands.
Full calibration, empty calibration
The sensor performs a full calibration or empty calibration
(see section Calibrate on page 8).
Teach Cancel
Resets the status of the Teach-In. Only available for
reasons of compatibility.
Device Reset
The sensor is restarted – like after power is interrupted.
Device Factory Reset
All parameters are reset to the factory defaults (see section
Reset to factory setting on page 9).
6.1.2 Device Access Locks
This parameter can be used to prevent different kinds of
access to the sensor. Setting the corresponding bit blocks
the respective access.
Write parameter
All write accesses to parameters and system commands
are blocked.
Data storage
The data storage mechanism is blocked and automatic
parameter calibration with the master is inhibited.
Local parametrization
The DI input is blocked, local operation of the sensor is not
possible.
6.1.3 Teach-In Channel
This parameter is available for compatibility reasons for the
function class Binary Data Channel of the Smart Sensor
profile.
Writing 0 resets the Teach-In Status .
6.1.4 Teach-In Status
This parameter is available for compatibility reasons for the
function class Binary Data Channel of the Smart Sensor
profile.
The parameter indicates the state and event of the
Teach-In. The value can be reset using the system
command Teach Cancel or writing Teach-In Channel .
6.1.5 Switching points
These parameters correspond to the Smart Sensor Profile
– Function Class Binary Data Channel.
The switching threshold for the sensor is defined by
Setpoint SP1.
Setpoint SP2 is present only for reasons of compatibility
with the Smart Sensor Profile and should always be set to 0.
