Review the 1734-4IOL IO-Link Add-on Profile
Overview
Device Parameter Behavior
IO-Link parameters are shown in the Add-on Profile (AOP) only for IO-Link
devices with IODD Advanced integration. Each parameter can have an
attribute of read-only (ro), read-write (rw), or write only (wo). The behavior of
parameters and the source for their values differ whether you are offline or
online.
Table 3 - IO-Link Device Parameter Behavior
The 1734-4IOL AOP offers four different tabs to describe the sensor
functionality and operation. These tabs are:
•
Common Tab:
General product information about the sensor
specifications and IO-link IODD information.
•
Identification Tab:
Sensor cat. no., series letter, general product
description including the current product firmware, and hardware
revisions.
•
Parameter Tab:
Different configurable parameters available in the
871TM.
•
Diagnosis Tab:
Monitor IO-Link communication characteristics.
For a complete listing of all sensor parameters and parameter definitions, see

Attribute
Offline
Online
Read-only
(ro)
Parameters are blank.
Parameter values are read from the connected IO-Link
device.
Parameters show “??” when communication breaks.
Read-write
(rw)
Parameter values are read from the
IODD file when the IO-Link device is
added.
Changes made to the parameters are
applied when the “OK” and “Apply”
buttons are clicked.
Parameter values can be edited and changes made to
the parameters are applied when the “OK” and “Apply”
buttons are clicked.
Changes are sent to the Master Module, which then
writes the changes to the connected IO-Link device.
Write only
(wo)
Parameter buttons are disabled.
Parameter buttons that could potentially alter the
Process Data are disabled.
Other parameter buttons that are enabled, result in
commands being sent to the connected IO-Link device.
