About this document
11.1.1
Purpose of this document
The ISDU descriptions in this document apply to IO-Link-enabled photoelectric sensors (Smart Sensors) with the
following principle of operation: WI180C-IOA00.
In some cases, functions may be described in this document which are not supported by individual sensors. The
functions in question are marked accordingly (
).
The specific functional scope of an individual sensor is described in full in the
Addendum to operating instructions
on
the relevant product page under
.
11.1.2
Intended use
Use IO-Link only as described in this documentation.
11.1.3
Symbols
NOTICE
This symbol indicates important information.
NOTE
This symbol provides additional information, e.g., dependencies / interactions between the described function and
other functions, or when individual functions are not supported by every sensor.
11.2
Description of IO-Link
IO-Link and control integration
IO-Link is a non-proprietary internationally standardized communication technology, which makes it possible to
communicate with sensors and actuators in industrial environments (IEC 61131-9).
IO-Link devices communicate with higher-level control systems via an IO-Link master. The IO-Link devices (slaves)
are connected to these via a point-to-point connection.
Different variants of IO-Link master are available. In most cases, they are remote fieldbus gateways or input cards
for the backplane bus of the control used.
To make it possible for an IO-Link sensor to communicate with the control, both the IO-Link master and the
IO-Link sensor must be integrated in the hardware configuration in the control manufacturer’s Engineering Tool.
To simplify the integration process, SICK provides sensor-specific device description files (IODD = IO-Link Device
Description) for IO-Link devices.
You can download these device description files free of charge:

Not all control system manufacturers support the use of IODDs. If third-party IO-Link masters are used, it is possi‐
ble to integrate the IO-Link sensor by manually entering the relevant sensor parameters directly during the hard‐
ware configuration.
To ensure that the IO-Link sensor can be easily integrated into the control program, SICK also provides function
blocks for many control systems. These function blocks make it easier to read and write the individual
sensor parameters, for example, and provide support when it comes to interpreting the process data supplied by
the IO-Link sensor. You can also download them free of charge from the homepage:
On the SICK YouTube channel, you can find a number of tutorials, which will help you to integrate SICK
IO-Link masters:
