1 Sensors covered by this manual

These instruction applies to all O200 sensors with IO-Link interface: O200.G, O200.S, O200:R

2 IO-Link Introduction

IO-Link is an IO technology standardized worldwide according to IEC 61131-9. It permits manufacturer­independent digital, bidirectional point-to-point communication. For this purpose, sensors are connected to
the IO-Link master via standardized 3-wire plug-in cables. IO-Link is available for various sensor
technologies and can also be integrated into small miniature sensors. See also here for more information.

With the IO-Link master, which bundles several sensors, the connection to the controller is made via the
respective fieldbus system. In addition, an Ethernet-based connection (with OPC UA) from the master allows
direct communication from the sensor to IT systems. IO-Link masters are available as field devices for
decentralized mounting or as versions for mounting in control cabinets. Many control suppliers also offer IO­Link input terminals and thus an IO-Link master implemented directly on the control. The maximum cable
length between sensor and master is 20 m. However, significantly longer connections from the sensor to the
controller can be realized by connecting a field master to a field bus system. This gives them maximum
flexibility in the connection solution.

As a member of the IO-Link Consortium, Baumer is involved in developing the standard and is one of the
first manufacturers to feature the new Smart Sensor Profile 1.1. in its sensors.

Figure 1 Example of a system architecture using IO-Link

2.1 SIO / DI Mode Mode

Each port of the IO-Link master can be operated either in SIO mode (standard in-out mode: according to the
latest specification DI mode for sensors and DQ mode for actuators) or in IO-Link mode and thus process
the information of all sensors. In SIO mode, the binary switching output (NPN, PNP or push-pull) of the
sensor is used. In IO-Link mode, the output of the sensor (pin 4) is used as a bidirectional, digital interface to
exchange measurement and diagnostic information.

15.08.2018/ Frauenfeld, Switzerland

2.2 IO-Link Communication Mode

The IO link communication mode is initiated by the master (PLC) with a standardized command sequence,
this sequence is called “wake-up”. After successful completion of the wake-up sequence the IO link
communication starts.

Data is the most important basis for process and product optimization. With the help of IO-Link, valuable
additional data can be made accessible. Sensor and Master can exchange two different types of data (cyclic
and acyclic data).
More information can also be found here.

2.2.1 Cyclic data

Transmitted in real time. They are used for process control in the automation system. These can also be
transferred to other IT systems via IO-Link.

2.2.2 Acyclic data

Through this data stream, sensors (IO devices) can be parameterized. Additionally this data stream also
allows to transmit data for identification and analyzation. The figure below shows the different types of data
and their value for the application.

Figure 2 Different IO Link data streams

15.08.2018/ Frauenfeld, Switzerland

2.3 IO-Link Device Description (IODD)

Each IO-Link Device has a device description file, the so-called IODD (IO Device Description). This contains
data about the manufacturer, article number, functionality, software version etc., which can be easily read out
and further processed by the automation system. Each device, i.e. each sensor, can be uniquely identified
both via the IODD and via an internal device ID. The identification data of the sensor also includes device or
application descriptions that can be freely assigned by the user. The IODD consists of several files: a main
file and optional external language files (both in XML format), as well as image files (in PNG format).

2.4 Off-Line Parametrization

Off-line sensor parameter adjustment via convenient user interfaces in the PC (via USB Master) or via
Wireless App (via Wireless Master). Sensors can be conveniently configured at the desk and installed
without further teach-in.

Even if IO-Link is not implemented in the machine control, sensors can be operated in SIO mode and use
this advantage

2.5 Adjustable switching sensor (AdSS)

Additionally, the sensors described in this manual can be operated as “adjustable switching sensors (AdSS)”
according to the Smart Sensor Profile. When treated as AdSS the sensors-Master communications happens
via a fully standardized command set. Thus operation without IODD file is possible.

3.1 Signal Path

The signal path describes the rough position of a parameter in the signal processing chain. The path starts
with the measuring value in the top left corner and finishes either with a physical pin (top right) or as output
via the process data (bottom right).

Figure 3 Illustrates the signal path from raw data to an output either through a physical pin (top right) or as
output via the process data (bottom right)

15.08.2018/ Frauenfeld, Switzerland

3.2 Process Data

With the sensor in the IO-Link communication mode, process data is cyclically exchanged between the IO­Link master and the device. Process data is exchanged to and from the sensor (SensorMaster). The
master does not need to explicitly request these process data.

3.2.1 Process Data-In

Process Data-In is sent from the sensor to the master (Sensor  Master).

Measurement Data Channel (MDC)

The Process Data Input is an 32bit string and structured according to the Smart Sensor Profile definition
PDI32.INT16_INT8.

Bit 0: SSC1 (Switching Signal Channel 1)

This bit is the digital representation of a switching output.
Bit 0 = 0 → No object is being detected (Logic: Normal)
Bit 0 = 1 → An object is being detected (Logic: Normal)
See section 4.3 to learn how to configure this bit

Bit 2: Quality

The quality bit signals that the signal quality has fallen below the configured threshold.
It is directly connected to the weak signal indication LED (section 4.6.2)

See section 4.7 to learn how to configure this bit

Bit 3: Alarm

The alarm bit indicates that there is a detectable problem with the configuration or function of the sensor.
Bit 3 = 0 → Sensor operates properly.
Bit 3 = 1 → A problem with either the sensor configuration or function was detected.

Bit 5: Switching Signal Channel 4 (SSC4), Switch Counter Function

By configuring SSC4, it is possible to set up a binary signal related to the number of switchcounts of SSC1.
An auto-reset and timefilters are included, to be able to create a full-featured counter being able to count lot
sizes without any need to code software on the PLC.

See section 4.3.4 to learn how to configure this bit.

Bit 8 to 15: Scale

Value is the exponent to the power of ten, applicable to the value of the Measurement Data Channel (MDC)
Example:

- Value of MDC 1000

- Unit m

- Scale -6

- Means 1000*10

-6

m or 1000 m

As O200 sensors only provide measuring values where no scale factor is required, the scale factor is set
fixed to 0 (zero).

Bit 16 to 31: MDC / Measurement Value

MDC stands for measurement data channel. Via this channel the distance value or the switch counts of
SSC1 or 4 can be read out as 16 bit integer value. See section 4.2 to learn how to configure the MDC.

3.2.2 Process Data-Out

4.3 Configuration - Switching Signal Channel (SSC)

The sensor features two different switching channels. Switching Signal Channel SSC1 is reserved for object
detection.
Switching Channel 4 includes a counter function with an auto-reset. All switching channels can be adjusted
individually via IO-Link. All switching channels can be mapped to the MDC as well. Then they will show the
counts detected by the channel.

For more information about how to set-up the Counter/SSC4 channel and its behavior, please see section

4.3.4.

4.3.3 Timefilter

This changes the timing of the switching signals, for example to avoid bouncing/suppress false switching
operation. The ability to directly parametrize and configure the timing on the sensor itself, removes the need
to have additional coding on the PLC or to use pulse stretching adapters.

The described time filters can be configured and applied to each SSC individually.

4.3.3.1 Response Delay Time

The response delay time defines the time, the measurement value needs to be above (single point mode) or
inside (window mode) the switchpoints of the related SSC until its status changes to active (or inactive, if the
logic is inverted as described in section 4.3.2.1)

When to apply?

- To avoid the detection of small peaks/false switching operations due to structure changes of the

background or similar.

- To avoid wrong switching of known disturbances such as the wheel of a mixer

- To avoid bouncing.

- To optimize the timing of the execution of a subsequent actor triggered by the outssput of the sensor.

4.3.4 Counter / SSC4

For each individual SSC a switching counter is implemented, which can be used as diagnosis data or also as
measurement value. The number of counts of each channel can also be mapped to the measurement data
channel MDC by adjusting the MDC source (See section 4.2.3).
Trigger of counter is on positive slope of related SSC.

By configuring SSC4, it is also possible to set up a binary signal related to the number of switchcounts of
SSC1. An auto-reset and timefilters are included, to be able to create a full-featured counter being able to
count lot sizes without any need to code software on the PLC.

As all SSCs, SSC4 can also be mapped to the digital output giving the possibility to create a stand-alone lot­size counter.

In section 3.1, the signal path is decribed more detailed, to illustrate how the counter module is implemented.
In section 4.3.4.2 the behavior depending on the configuration is explained.

4.3.4.1 SSC4 Configuration

In general the SSC4 offers the same features as the SSC1 and SSC2 based on distance (See 4.3.2),
including also timefilters.
Exceptions:

- No hysteresis settings as there are only incremental counts.

- Additional parameters to adjust like SSC4 Source and SSC4 Auto-Reset.

5 Teach Commands

By using teach commands, the setpoints of the switching signal channel SSC1 can be defined by teach-in
the position of the object or reference.
Next to teach-by-value which can be applied as described in section 4.3.1, using teach commands makes it
easy to compensate individual variations such as mechanical and mounting tolerances.

There are two different procedures available – static or dynamic – which can be individually chosen
independent of the switching mode of the selected SSC

- Static: Defines the setpoints by teach-in the positions of non-moving objects

- Dynamic: For moving and small objects. Analyzes the minimum and maximum distances within

a time frame to define the setpoints.

The teach-in procedures are described more detailed in section 5.2 (Static) and 5.3 (Dynamic).

The switching behavior of each switching signal channel depends on the configuration (Switching Mode,
Channel Logic, …) described in section 4.3.2.

5.1 Teach Channel Selection, TPO & Teach Status

The described teach commands can be applied to individual switching signal channels. Before proceeding
with the teach-in procedure, make sure to select the SSC that should be addressed.

Furthermore different information are available to indicate the current mode and teach-in state of the
selected switching signal channel to help to execute the right commands described in section 5.2 and 5.3.

5.2.1 Single Point Mode: 1-Point Teach

If the selected SSC is configured as Single Point mode (Section 4.3.2.1), following command sequence is
required to teach-in SP1:

Command sequence:

- Place object (O200.G), reflector (O200.R) or reference (O200.S) at desired position

- Execute Teach SP1 to teach-in the position

- Execute Teach Apply to store the resulting setpoint

By executing Teach Cancel the teach-in procedure can be canceled at any state, as long Teach Apply has
not been used before.

Figure 24: O200.G/O200.R: Single Point Teach, switching behavior

Figure 24 shows the switching behavior of the selected SSC if the teach-in was successful.
In single point mode, the TPO/Teach Point Offset will be added on the teached-in value to define the
setpoint.

O200.G: SP1 = TP + TPO
O200.R: SP1 = TP * TPO

Figure 25: O200.S: Single Point Teach, switching behavior

Figure 25 shows the switching behavior of the selected SSC if the teach-in was successful.
Regarding the O200.S SmartReflect sensors, the SP1 is related to the background position / position of the
reference part of the machine. Tolerance describes the allowed distance variation of the reference to be still
being detected.
