Exploring the 42EF IO-Link Parameters
38
The parameter tab displays the sensor parameter settings, as well as enabling the
user to read data from the sensor or teach the sensor by writing new values.
The parameter section is divided into three sections:
• Operation Configuration
• Sensor Configuration
• Counter/Timer Configuration
• Data Mapping Configuration
Operation Configuration: In this section, operators are able to change the
function of the sensor outputs while operating in Standard IO mode and 
IO-Link Mode. The Triggered sub-section describes the parameters affecting the
sensor output.
Set-Point – Threshold allows operators to enter the signal value required for
the sensor output to turn ON (threshold) upon target detection. That means
that the sensor signal level must be higher than the threshold for the output to
turn ON. The default value for this parameter is 1000 with acceptable values
between 505 and 12923.
Polarity changes the sensor output to operate as Light Operate (Non Inverted)
and Dark Operate (Inverted) in relation to Pin 4. For complementary (Light and
Dark Operate) models, changing this parameter from Not Inverted to Inverted
swaps Pin 2 to function as Light Operate and Pin 4 to function as Dark Operate.
For PNP and NPN models, changing this parameter from Light Operate to Dark
Operate changes the function for both outputs PNP and NPN at the same time
(for example, Changing from Not Inverted to Inverted makes both outputs
(NPN and PNP) output to be Inverted.
Hysteresis displays the sensor output hysteresis value. The real value for
hysteresis is this value shown on this parameter divided by 100.
Pin 2 Mode enables the operation of the output on pin 2 in IO-Link Mode.
When connecting the sensor in IO-Link mode, pin 2 is disabled by default and
could be changed to either operate as Light Operate or Dark Operate. This
parameter is ideal for applications where the response time is critical for the
application as IO-Link response time may not be fast enough to address the
application needs.
Sensor Configuration: In this section, the operator is able to change when the
sensor Indication LEDs should display marginal conditions. Two parameters are
displayed: Margin Level Low Multiplier and Margin Level High Multiplier
Margin Level – Low Multiplier allows users to define when the green LED
should start flashing to reflect a signal level that is below the threshold. The
default value for this parameter is 0.8 with multiple selection options ranging
from 0.5 to 0.8 in increments of 0.1X.
Margin Level – High Multiplier allows users to define when the green LED
should stop flashing to reflect a signal level that is higher than the threshold. The
