Unused outputs must not be wired. In cable versions with unused cores, these cores

must be insulated. Do not exceed admissible cable bending radii. Prior to electrical
connection of the product, the system must be disconnected from the power supply.
In areas where screened cables are mandatory, they must be used as protection
against electromagnetic disturbances. If plug connections to screened cables are
made by the customer, an EMC version of the connectors should be used, and the
screen must be connected to the connector housing across a large area.

2 IO-Link introduction

These operating instructions contain a description of the most important aspects of the IO-Link interface
which are required for understanding the configuration options. For detailed information about IO-Link and all
specifications, go to www.io-link.com .

IO-Link is a standard interface for sensors and actuators. The device (sensor, actuator) and IO-Link master
are interconnected as a point-to-point connection. Communication between master and device takes place
bi-directionally via the device connecting line. Via this interface values can be read out and it is possible to
configure the sensor via IO-Link. The sensor can be operated in two modes: standard input/output mode
(SIO mode) and IO-Link communication mode.

The master switches the sensor to IO-Link communication mode. In this mode, process data are
continuously sent from the sensor to the master and demand data (parameters, commands) are written to
the device or read off it.

2.1 SIO mode

After start-up the sensor is in SIO mode. In this mode the sensor functions as a normally switching sensor.
On the master side the IO-Link port is switched as a normal digital input. The sensor can be used like a
standard sensor without IO-Link. Diverse functions can, however, only be controlled via IO-Link.

2.2 IO-Link communication mode

With a so-called "wake-up" the sensor is switched by the master into "communication mode". In the process
the master attempts to find a connected device through a defined signal on the switching line. If the sensor
responds, communication parameters are exchanged and afterwards cyclical transmission of process data is
initiated.
In IO-Link communication mode:

• Process data can be read.

• Parameters can be read off the sensor.

• Parameters can be written to the sensor.

• Commands can be sent to the sensor (e.g. teaching the switching point, restoring to factory setting,

etc.).

In the process data cyclical data such as outputs or quality data are transmitted to the superordinate control.
The master can leave the IO-Link communication mode again with a "fall back", and the sensor continues to
operate in SIO mode until a new "wake up".

In IO-Link communication mode, sensor behavior can be adjusted in SIO mode so that the sensor can easily
be parameterized according to requirements and then operate as a "normal" sensor without the IO-Link
master. Alternatively, the sensor can also be operated in IO-Link communication mode, enabling use of the
full range of functions via process data.

2.3 IODD (IO-Link device description)

The IODD describes the IO-Link device and can be downloaded at www.baumer.com. It consists of a set of
XML and PNG files. An engineering tool or diagnosis tool reads the IODD of a sensor and therefore knows
its:

• Identification (manufacturer, designation, article number, etc.)

• Communication characteristics (communication speed, frame type, etc.)

• Parameters and commands

• Process data

• Diagnosis data (events)

Sensor data that can be viewed and changed is defined by the IODD. The manner of data representation
and manipulation is defined by the control manufacturer and is therefore sensor-independent.

3 Sensor in SIO mode

In SIO mode the sensor operates according to the factory settings or the settings adjusted by the user via
IO-Link. The range of functions in SIO mode is sensor-specific.

4 Sensor in IO-Link communication mode

4.1 Process data

If the sensor is in IO-Link communication mode, data are periodically exchanged between the IO-Link master
and the device. These data consist of process data and possible commands and parameters to the sensor.
In the process data the current measuring value and status bits like output, quality data, etc. are transmitted
to the master. The process data do not have to be explicitly queried by the master.

4.1.1 Process data structure

Figure 1 shows the process data structure. A brief description of the individual data is provided in the
following.

4.1.1.1 Back-up

Bit4…Bit15 serve solely as a back-up and are reserved with the value 0.

4.1.1.2 Meaning of status information

Bit 0: Alarm

The alarm bit indicates whether an object is in the defined scanning range (e.g. 50 to 400 mm)
Bit0 = 0 → There is an object is in the scanning range
Bit0 = 1

→ There is no object in the scanning range
