The IO-Link master module connects IO-Link sensors and actuators with the higher-level con-
trol system. The device has an Ethernet interface and fieldbus-independent I/O electronics with
IO-Link master functionality (Class A ports). Via the Ethernet interface, the IO-Link master is con-
nected 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 up to 16 sensors and actuators via 16 con-
figurable digital channels.

4.4 Functions and operating modes
4.4.1 Multiprotocol technology
The device 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 multiprotocol 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 supports the following Ethernet profile-specific functions:
PROFINET
nFSU (fast startup)
nTopology detection
nAddress allocation with LLDP
nMedia redundancy protocol (MRP)
EtherNet/IP
nQC (QuickConnect)
nDevice Level Ring (DLR)

4.4.2 IO-Link channels
The IO-Link master module TBEN-L…-8IOL has eight Class A IO-Link channels.
The four eight IO-Link channels at pin 4 of the M12 connectors can be parameterized inde-
pendently of each other and operated either in IO-Link mode or as universal DXP channel (DI or
DO) in SIO mode. The maximum output current per DXP output in SIO mode at pin 4 is 0.5 A.
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. The IO-Link devices are integrated in the GSDML file of the
master, which allows the user to select the devices from the device library (for example in TIA
Portal) like sub modules on a modular I/O system and integrate them into the project. Plain-text
access to all device properties and parameters is possible. IO-Link device-specific data such as
measuring ranges, switching points, pulse rates, etc. can be set directly in the engineering sys-
tem without programming or additional software [}125].
NOTE
Data storage [}158] is not possible when configuring IO-Link devices with SIDI.
IODD Configurator
The IODD Configurator is a browser-based configuration tool and called from the web server of
the IO-Link master module.
NOTE
To call up the IODD Configurator, a login in the web server of the IO-Link master is
required [}28].
The IODD Configurator allows access to the plain text of all relevant IO-Link device parameters
and supports and simplifies the parameterization, commissioning and maintenance of IO-Link
devices.
IO-Link device-specific information is made available directly in the IO-Link master. The IODD
suitable for the connected IO-Link devices is loaded into the IO-Link master and interpreted by
the master. IO-Link events, diagnostics and process data of the IO-Link devices can thus be in-
terpreted directly in the web server of the IOL master according to the specific device. In addi-
