Review the 1734-4IOL IO-Link AOP Chapter 9
• Pin 2 Mode enables the operation of the sensor as a standard 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
Normally Open or Normally Closed contact in standard I/O
application. This parameter is ideal for applications where the response
time is critical for the application as IO-Link response time is not fast
enough to address the application needs.
Sensor Configuration
In this section, the operator is able to change when the sensor indication
indicator displays marginal conditions. Two parameters are displayed:
Proximity Alarm Level and Margin Level Low Multiplier.
• Proximity Alarm Level allows you to view a signal level that is below the
threshold. The default value for this parameter is 0.8 mm (0.03 in.).
• Margin Level: Low Multiplier allows you to view when the orange status
indicator starts flashing to reflect a signal level that is below the
threshold. The default value for this parameter is 1.1 mm (0.04 in.).
Counter/Timer Configuration
In this section, the operator is able to configure the sensor counter and timer
functions. Two main parameter subsections are shown: Counter and Timer.
• Counter: When enabled, the counter counts up on any transition from
OFF to ON.
– Mode: Allows you to enable or disable the counter function. This
parameter is Read/Write.
– Reset: Allows you to reset the counter function. This parameter is
write-only and can be enabled via the AOP or sending explicit
messages. See Appendix B for Index information.
– Counter: This parameter is read only and displays the current count.
• Timer: Measures the amount of time the output is present and absent up
to a maximum period of 4 seconds.
– Mode: Allows you to enable or disable the timer function. This
parameter is Read/Write.
– Reset: Allows you to reset the timer function. This parameter is
write-only and can be enabled via the AOP or sending explicit
messages. See Appendix B for Index information.
– Duration Triggered: Displays the amount of time the target was
detected. The maximum value that this parameter displays is
4095 ms.
Timer must be enabled.
– Duration Not Triggered: Displays the amount of time the target was
not detected. The maximum value that this parameter displays is
4095 ms. Timer must be enabled.
