3 IO-Link – Basics

3.1 IO-Link- interface – the fieldbus independent communication interface

IO-Link is a fieldbus-independent communication interface for sensors and actuators.

It is based on the IO-Link specification "IO-Link Interface and System Specification" version 1.1.2,
November 2012, and on the IEC 61131-9 (2013-09), ed. 1.0, „Programmable controllers - part 9: Sin­gle-drop digital communication interface for small sensors and actuators (SDCI)“.

IO-Link is a point-to-point connection between an IO-Link device (e.g. sensor, I/O hub, valve termi­nal) and the IO-Link master. Up to now, the binary connection was only designed for transferring
switching information, but IO-Link now allows 2 bytes to be transferred normally in a 2.3 ms cycle
via a combined switching status and data channel.

Other information can be exchanged in addition to the process values, such as parameters or diag­nostic messages.

This enables communication with sensors and actuators down to the "last meter" to be established
for universal communication.

Further information: : www.io-link.com

3.1.1 Communication

 Standard I/O-connection technologies in point-to-point connection, unshielded, 20 m wire

length

 Cyclic process data transfer in typ. 2.3 ms

 Parallel service data exchange without any impact on the process data

 Communication via 24 V-pulse modulation, standard UART protocol

 Communication between master and device in 3 different transmission speeds

–

4.800 Baud (COM 1)

– 38.400 Baud (COM 2)

– 230.400 Baud (COM 3)

3.1.2 Data transmission

Basically 4 different types of data exist, which are transmitted either cyclically or acyclically.

 Process data  cyclic data exchange

 Value status  cyclic data exchange

 Device data  acyclic data exchange

 Events  acyclic data exchange

V01.0| 2016/04

Process data:

The devices' process data are transmitted cyclically, whereas the process data size is defined
through the device. The device process data can contain from 0 to 32 Byte (for both in- and output).

11

D301368 - 0815 TBEN-S2-4IOL

IO-Link – Basics

Value status:

The value status displays if process data are valid or not. It is transmitted cyclically with the process
data.

Device data:

Device data are parameters, identification data and diagnostic information. The transmission is
done acyclically and only on demand of the IO-Link master.

Events:

Events are error messages or warnings/maintenance data. Error messages are transmitted from the
device to the PLC or similar via the IO-Link master. The IO-Link master itself can also transmit events
and status information. Those events can be for example an open circuit, communication loss or an
overload.

3.1.3 Transmission media

IO-Link does not require any special wiring. The sensors and actuators can continue to be connected
using the proven, attractively priced and unshielded industrial cables.

The operating modes available for selection are the standard switch mode and the communication
mode.

4 TBEN-Lx-8IOL

4.1 Product identification

The TBEN-Lx-8IOL is the 8-channel IO-Link-master module of the product family TBEN-L.

Like all modules of the TBEN-L-product family, the TBEN-Lx-8IOL is a device with Turck multiproto­col functionality, which means, it can be used in the three Ethernet protocols PROFINET, EtherNet/
IP™ and Modbus TCP. An integrated Ethernet-switch allows the building up of a line topology.

Besides the eight IO-Link channels (4 with IO-Link Class A and 4 with IO-Link Class B), the TBEN-Lx­8IOL provides four universal digital DXP-channels (PNP).

The eight IO-Link channels can be parameterized independently and can optionally be operated in
IO-Link mode (IOL) or in standard I/O mode (DI mode).

Thanks to the "Simple IO-Link Device Integration (SIDI)“, Turck IO-Link devices can directly be
selected from the device GSDML in PROFINET.

The four universal digital channels are designed as DXP-channels and can therefore be parameter­ized as in- or output.

Properties:

 8-channel IO-Link master according to IO-Link specification V1.1

–

four IO-Link Class A-channels (C0 to C3)

– four IO-Link Class B-channels (C4 to C7)

 4 universal digital channels, PNP, channel diagnostics, 0.5 A at the connectors C0 to C3

 Connector for voltage supply:

–

TBEN-L4-8IOL: 7/8“ (4-pole)

– TBEN-L5-8IOL: 7/8“ (5-pole)

ATTENTION!

Connection of Class A devices to Class B ports

Loss of the galvanic isolation

 Only use Class A devices with signals on pin 1, pin 3 and pin 4 at Class B ports. 

The connection of Class A devices with signals on pin 2 and pin 5 leads to the loss of the

Mode

0000 IO-Link without 

validation A

Pin 4 is operated in IO-Link mode.
The master does not check if the connected device matches the
configured one.

0001 IO-Link with family

compatible device

4 is operated in IO-Link mode.
The master checks if the Vendor ID and the MSB of the Device ID
(this byte defines the product family) of the connected device
match those of the configured one.
If the master detects a mismatch, the IO-Link communication is
established, but there is no process data exchange. The device
remains in the safe state (Pre-Operate). Parameters and diagnos­tic information can be read and respectively written.

0010 IO-Link with compati-

ble device

4 is operated in IO-Link mode.
The master checks if the Vendor ID and the Device ID of the con­nected device match those of the configured one.
If the Vendor ID matches, but the Device ID not, then the master
tries to write the Device ID to the device.
If the writing is successful, then the device is a compatible one,
process data exchange is possible.
If writing the Device ID is not successful, then process data
exchange is not possible. The device remains in the safe state (Pre­Operate). Parameters and diagnostic information can be read and
respectively written.

0011 IO-Link with 

identical device

4 is operated in IO-Link mode.
The master checks if the device type (Vendor ID and Device ID)
and the serial number of the connected device match the data of
the configured one.
If the master detects a mismatch, the IO-Link communication is
established, but there is no process data exchange. The device
remains in the safe state (Pre-Operate). Parameters and diagnos­tic information can be read and respectively written.

0100 DI (with parameter

access)

Pin 4 is generally operated as simple digital input.
However, an acyclic parameter access from the PLC or the DTM is
possible.
The IO-Link master starts the port in IO-link mode, parameterizes
the device and sets the port back into DI-mode. The port remains
in DI mode until a new IO-Link request is sent from the higher­level control.
Data storage is not supported.
Connected devices have to support the SIO-mode (DI-mode).

case the data storage has to be deactivated (data storage mode: 11 = deactivated, clear).

For fast applications (e.g. tool changing applications) th
The start-up time defined in the IO-Link specification (TSD = Device Detection Time) is reduced.

00 no A The start-up time is within the specified range (0.5 s). All IO-Link

devices in accordance with the specification can be operated.

01 yes The start-up time is reduced to approx. 100 ms. It is not supported

by every IO-Link device.
It can thus be necessary to check if the used IO-Link device starts
in this mode.

4.6.1 Adaptation of the process data mapping

The mapping of process data can be adapted application-specifically via the IO-Link-master's
parameterization.

Depending on the used fieldbus, it can be necessary to swap process data word-wise, double word­wise or completely in order to align them to the data structure in the PLC.

The process data mapping is determined channel by channel through the parameters "process
input data mapping" and "process output data mapping"" (see Parameters, page 22).

Example mapping for field buses with Little Endian-format:
