Review the 1734-4IOL IO-Link AOP
Service Function
This section contains multiple parameters that allow operators to enable
additional sensing functionality. This parameter can only be accessed through
explicit messages as described in
Explicit Messaging Examples on page 79
.
• Restore Factory Settings: A write-only command and sets the current
sensor settings to their factory default values. This parameter can only
be accessed via explicit message as defined in
.
• Device Reset: A write-only command that performs the same function
as a power cycle of the sensor.
• Location Indicator: Activates the location indication sensor
functionality. When enabled, the sensor user interface (green and
orange indicators) starts flashing synchronously until the operator
disables this function. This parameter is useful when there are multiple
sensors near each other.
• Status Indicators Enabled: This parameter allows operators to turn the
user interface status indicators (green and orange) OFF or ON. This
parameter is ideal to accommodate applications where the status
indicators must be turned OFF.
• Error Count: Displays the number of errors.
• Device Status: Displays the status of the device.
• Last Event: Displays the code for the last event the sensor initiates.
Operation Information
In this section, the operator is able to monitor the sensor operating hours since
inception and power up.
• Operating Hours – Since Inception: displays the total operating hours
that the sensor has been running since the first time it was powered ON.
This value is not lost during factory reset. The information that is
displayed in this parameter is represented in hours.
• Operating Hours – Since Power Up: Displays the total operating hours
that the sensor has been running since the last time the sensor power was
cycled. This value is reset to zero every time that the sensor loses power.
