4 System Description IO-Link
IO-Link is a fieldbus independent communication interface for sensors and actuators. Signals
and energy can be exchanged between any networks, fieldbuses and backplane buses via a di-
gital, serial point-to-point connection.
Each IO-Link system consists of an IO-Link master and an IO-Link device (e.g. sensor, I/O hub,
valve block). An IO-Link master is provided with at least one IO-Link port (channel). One IO-Link
device can be connected to each port. The system components are interconnected according
to the port specification via unshielded 3-wire or 5-wire standard cables.
The IO-Link technology is described in the “IO-Link Interface and System Specification” and
IEC61131-9. IO-Link capable devices comply either with specification V1.0 or specification V1.1.
The properties, functions and parameters of the IO-Link device are represented in an electronic
device description (IODD). The IODDs for Turck devices can be downloaded via the Turck Soft-
ware Manager and can also be obtained free of charge from www.turck.com . The IODDs of all
devices have the same structure and contain the following information for system integration
nCommunication properties
nDevice parameters with value range and default value
nIdentification, process and diagnostic data
nDevice data
nText description
nPicture of the device
nLogo of the manufacturer
The structure of the IODD is defined by the IO-Link specification and is the same for all IO-Link
devices. The IODD is based on indexes. The communication properties, device parameters,
identification, process, diagnostic and device data are assigned to fixed indexes in the IODD, via
which the parameters can be controlled. Some indexes are further divided by sub indexes.
4.1 Features
nPoint-to-point connection (max. cable length: 20 m)
nUnshielded 3-wire or 5-wire standard cables
nCyclical process data transmission
nAcyclical data transmission, e.g. device data and events
nCommunication between IO-Link master and IO-Link device possible in three transmission
rates
nParallel exchange of device data without influencing the process data
nCommunication via 24 V pulse modulation, standard UART protocol

V01.00 | 2019/11 11
4.2 System architecture
At least one IO-Link master and one IO-Link device (e.g. sensor or actuator) are required for IO-
Link communication. IO-Link master and IO-Link device are interconnected via an unshielded 3-
wire or 5-wire standard cable. The setting can be carried out with a configuration tool or via the
fieldbus level.
The IO-Link master establishes the connection between IO-Link device and the higher-level
control system. An IO-Link master can have several IO-Link ports. Only one IO-Link device can
be connected to each port.
IO-Link hubs also make it possible to integrate devices without an IO-Link output in automation
systems via IO-Link.
Standard tools and functions are provided for the integration, commissioning and configura-
tion of the IO-Link communication.

System Description IO-Link
Operating modes

4.3 Operating principle
IO-Link is a digital point-to-point connection between an IO-Link master and an IO-Link device.
Process data and other information such as parameters and diagnostic messages are trans-
ferred with a 24 V pulse modulation via a combined switching status and data channel (C/Q).
IO-Link communication is independent of the fieldbus used.
4.4 Operating modes
The operating mode can be set separately at any port of the IO-Link master.
Two operating modes are available for the IO-Link master:
nIO-Link mode: IO-Link communication possible
nStandard I/O mode (SIO): digital I/O communication
IO-Link communication is implemented via the switching and communication cable (C/Q).

Fig.2: IO-Link communication via C/Q
During initialization the ports of the IO-Link master behave like a normal digital input. The IO-
Link devices are operated in IO-Link mode. A command of the higher-level IO-Link master es-
tablishes IO-Link communication in IO-Link mode. This command is called the “Wake-up re-
quest”.
4.4.1 IO-Link mode
In IO-Link mode communication takes place between an IO-Link master and an IO-Link device.
Communication always starts from the IO-Link master.
Transmission speed between IO-Link master and IO-Link device
Three transmission rates are defined in the IO-Link specification:
n4,8 kBaud
n38,4 kBaud
n230,4 kBaud
Each device supports only one transmission rate, an IO-Link master supports all transmission
rates. The transfer time of the cyclical process data is determined by the telegram length as well
as the delay times in the device and the master. With a transmission rate of 38.4 kBaud and a
telegram length of 2 byte the transmission time is typically 2.3 ms.
Response times
The response time of the IO-Link system provides information on the frequency and speed of
the data transmission between IO-Link master and IO-Link device. This response time depends
on the following factors:
nMinimum cycle time: Intervals defined in the IODD in which the IO-Link master addresses the
IO-Link device. Different minimum cycle times can be defined for different devices.
nInternal processing time of the IO-Link master and the IO-Link device

V01.00 | 2019/11 13
Cyclical and Acyclical Communication
The data exchanged between IO-Link master and the IO-Link device can be divided into cyclical
process data and acyclical data. Process data and value states are transferred cyclically. Acyc-
lical data is transferred separately to cyclic process data. Acyclical data includes device data,
parameter functions and events such as diagnostic information, which is only transferred on re-
quest. The two communication types are independent of each other and do not interact.
Cyclical communication
Process data Value status (port qualifier)
n0…32 bytes of process data possible per
device (each input and output)
nProcess data size determined by the device
nThe Port Qualifier indicates whether the
process data is valid or not.
Acylical communication
Device data Value status (port qualifier)
nParameters, identification data or
diagnostic information
nData exchange on request of the IO-Link
master
nDevice data can be written to the device or
read from the device.
nDevice indicates event to master: Error mes-
sages and warnings
nMaster indicates event to device: e.g. cable
break or communication abort
Combining IO-Link devices with different specifications
Only devices of specification V1.0 can be operated on IO-Link masters of specification V1.0.
Devices of specification V1.0 and V1.1 can be operated on IO-Link masters of specification V1.1.

Data storage mode
NOTE
Data storage mode is only available for devices complying with the IO-Link specifica-
tion V1.1.
Data storage mode makes it possible to replace IO-Link devices without the need for a reconfig-
uration.
The IO-Link master or the IO-Link device save the device parameters set in the previous config-
uration. In data storage mode the parameter data memories of IO-Link master and IO-Link
device are synchronized. If data storage mode is activated in the IO-Link master, the master
writes the stored device parameters to the new device after a device is replaced. The applica-
tion can be restarted without having to perform a new configuration.

4.4.2 Standard I/O mode (SIO mode)
In standard I/O mode IO-Link devices behave like digital sensors or actuators. In this mode the
devices only send input or output data to the higher-level instance. IO-Link access to the device
is not possible.

5 Product Description
The devices are designed in a fully encapsulated housing with degree of protection IP65/IP67/
IP69K.
The IO-Link master module TBEN-LL-8IOL has eight IO-Link ports for connecting IO-Link
devices. The IO-Link ports at the connectors X0…X3 are designed as Class A ports. The IO-Link
ports at the connectors X4…X7 are designed as Class B ports. In addition to the four IO-Link-
channels, four universal digital DXP channels (PNP) are available. The eight IO-Link channels
can be parameterized independently of each other and operated either in IO-Link mode or in
SIO mode
(DI).
With Turck's "Simple IO-Link Device Integration (SIDI)", IO-Link devices can be directly integ-
rated into PROFINET via the GSDML file of the TBEN-LL-8IOL.
The 4 universal digital channels are designed as DXP-channels and can therefore be parameter-
ized as in- or output.
For connecting the supply voltage, the device has 5-pin M12 connectors.
The multiprotocol device can be operated with the three Ethernet protocols PROFINET, Ethern-
Net/IP and Modbus TCP mentioned above by automatic protocol detection without user inter-
vention

5.3 Operating principle
The IO-Link master module TBEN-LL-8IOL connects IO-Link sensors and actuators with the
higher-level control system. The device has an Ethernet interface and fieldbus-independent I/O
electronics with IO-Link master functionality (Class A and Class B ports). Via the Ethernet inter-
face, the IO-Link master is connected to an (existing) Ethernet network as an EtherNet/IP device,
Modbus TCP slave or PROFINET device. During operation, the process data is exchanged
between Ethernet and IO-Link. In addition the devices can process signals from sensors and ac-
tuators via four configurable digital channels.

The devices can be used in the following three Ethernet protocols:
nModbus TCP
nEtherNet/IP
nPROFINET
The required Ethernet protocol can be detected automatically or determined manually.
Automatic protocol detection
A multi-protocol device can be operated without intervention of the user (which means,
without changes in the parameterization) in all of the three Ethernet protocols mentioned.
During the system start-up phase (snooping phase), the module detects which Ethernet pro-
tocol requests a connection to be established and adjusts itself to the corresponding protocol.
After this an access to the device from other protocols is read-only.
Manual Protocol Selection
The user can also define the protocol manually. In this case, the snooping phase is skipped and
the device is fixed to the selected protocol. With the other protocols, the device can only be ac-
cessed read-only.
Protocol Dependent Functions
The device Supported the following Ethernet protocol specific functions:
PROFINET
nFSU - Fast Start-Up (prioritized startup)
nTopology discovery
nAddress assignment via LLDP
nMRP (Media Redundancy Protocol)
EtherNet/IP
nQC – QuickConnect
nDevice Level Ring (DLR)
5.4.2 IO-Link channels
The IO-Link master module TBEN-LL-8IOL has four Class A IO-Link ports (slots X0…X3) and four
Class B IO-Link ports (slots X4…X7).
The eight IO-Link channels can be parameterized independently of each other and operated
either in IO-Link mode or in SIO mode (DI).

Simple IO-Link Device Integration (SIDI)
Turck's Simple IO-Link Device Integration (SIDI) simplifies the handling of IO-Link devices in
PROFINET engineering systems. Since the devices are already integrated in the GSDML file of
the master, the user can select the devices from the device library (for example in the TIA
portal) and integrate them into his project via drop-down fields as if the devices were submod-
ules of a modular I/O system. The user benefits from plain text access to all device properties
and parameters. Measuring ranges, switching points and pulse rates can be set directly from
the engineering system - without programming or additional software.
5.4.3 Configurable digital channels – functions
The device is provided with four digital channels, which can be configured as inputs or outputs
according to the application requirements. In all, up to four 3-wire PNP sensors or four PNP DC
actuators with a maximum output current of 0.5 A can be connected per input or output.

Fig.8: Grounding clip (1), grounding ring (2) and metal screw (3)
The grounding ring (2) is the module grounding. The shielding of the I/O level is permanently
connected to the module grounding. The module grounding is only connected to the refer-
ence potential of the installation when the module is mounted.
Shielding concept of the I/O modules (I/O level)
In the case of direct mounting on a mounting plate, the module grounding is connected to the
reference potential of the system via the metal screw in the lower mounting hole (3). If module
grounding is not desired, the electrical connection to the reference potential must be interrup-
ted, e.g. by using a plastic screw.
