Operating principle
The IO-Link master module TBEN-L…-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.

Functions and operating modes
5.4.1
Multiprotocol technology
The devices can be used in the following three Ethernet protocols:
n
Modbus TCP
n
EtherNet/IP™
n
PROFINET
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.
