3 For your safety
The product is designed according to state-of-the-art technology. However, residual risks still
exist. Observe the following warnings and safety notices to prevent damage to persons and
property. Turck accepts no liability for damage caused by failure to observe these warning and
safety notices.
3.1 Intended use
Due to the Turck multiprotocol technology, the multiprotocol I/O modules for Ethernet can be
operated in the Three Ethernet protocols PROFINET, EtherNet/P and Modbus TCP. The modules
detect the bus protocol automatically during the start-up.

digital sensors or actuators.
The devices meet the requirements for passive safety [}24] and can be used in the following
applications:
nApplications up to SIL CL2 (according to EN 62061:2016, section 6.7.7)
nApplications up to Category 3 and Performance Level d (according to EN ISO 13849-1: 2016)
Installation directly in the field is possible thanks to degrees of protection IP65, IP67 or IP69K.
Devices with Ex marking are suitable for operation in hazardous areas in Zone 2 and Zone 22.
The devices may only be used as described in these instructions. Any other use is not in accord-
ance with the intended use. Turck accepts no liability for any resulting damage.

Functions and operating modes
Hans Turck GmbH & Co. KG | T [phone] | [email protected] | www.turck.com V01.00 | 2022/10 | 11
4.3 Functions and operating modes
4.3.1 Multiprotocol technology
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 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
accessed 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)

Hans Turck GmbH & Co. KG | T [phone] | [email protected] | www.turck.com V01.00 | 2022/10 | 12
4.3.2 Digital modules – extended digital functions
In PROFINET, the extended digital functions are configured via device parameterization via
GSDML file. In EtherNet/IP, the functions are provided in special catalog files for RSLogix from
Rockwell Automation. In Modbus TCP the extended functions are configured via Modbus
registers. In addition to that, the functions are configurable via the device's web server or the
device DTMs.
The digital TBEN modules provide the following extended digital functions:
Digital filter
The function ”digital filter” extends the filter time of digital inputs to 3 ms. Digital input signals
can thus be reliably detected even when short-term interfering signals in rough environments
occur.
Impulse stretch
The function "impulse stretch" allows a detection of short input signals in longer PLC cycle
times by means of signal extension.
4.3.3 Turck Field Logic Controller (FLC ARGEE)
The device supports logic processing with the Turck Field Logic Controller (FLC ARGEE) func-
tion. This enables the device to perform small to medium complexity control tasks in order to
relieve the processing load on the central controller. The FLCs can be programmed in the
ARGEE engineering environment.
The ARGEE-FLC programming software can be downloaded free of charge from
www.turck.com.
The Zip archive SW_ARGEE_Environment_Vx.x.zip also contains the documentation for the pro-
gramming environment in addition to the software.

The fieldbus and the I/O level of the modules can be grounded separately.

Fig.6: 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.
I/O level shielding
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.
Fieldbus level shielding
The grounding of the fieldbus level can either be connected directly via the grounding clip (1)
or connected and routed indirectly via an RC element to the module grounding. If the ground-
ing is to be routed via an RC element, the grounding clip must be removed.
In the delivery state, the grounding clip is mounted.

Tighten M12 connectors with a tightening torque of 0.6 Nm.
Only use accessories that guarantee the protection class.
Always seal unused connectors with suitable screw caps or blind caps. The tight-
ening torque for the screw caps is 0.5Nm.
6.1 Connecting the device in Zone 2 and Zone 22
DANGER
Explosive atmosphere
Explosion due to ignitable sparks
For use in Zone 2 and Zone 22:
Only disconnect and connect circuits when no voltage is applied.
Only use connecting cables that are approved for use in potentially explosive
atmospheres.
Use all connectors or seal them with suitable screw caps or blind caps. The tight-
ening torque for the screw caps is 0.5 Nm.
Observe requirements for Ex approval.
6.2 Connecting the device in safety applications
WARNING
Intrusion of liquids or foreign bodies through leaking connections
Danger to life due to failure of the safety function
Tighten M12 connectors with a tightening torque of 0.6 Nm.
Always seal unused connectors with suitable screw caps or blind caps. The tight-
ening torque for the screw caps is 0.5Nm.

6.4 Connecting the power supply
For the connection to the power supply, the device has two 5-pin, L coded M12 connectors. V1
and V2 are galvanically isolated. The maximum tightening torque is 0.6 Nm.
Connect the device to the power supply according to the pin assignment shown below.
Always seal unused connectors with suitable screw caps or blind caps. The tightening
torque for the screw caps is 0.5 Nm.

Voltage Function
V1 System voltage: power supply 1 (incl. supply of electronics)
V2 Load voltage: power supply 2
NOTE
The system voltage (V1) and the load voltage (V2) are supplied and monitored
separately. If the permissible supply voltages are undershot, the voltages at the con-
nectors are switched off according to the supply concept of the module type. If V2 is
undershot, the PWR LED changes from green to green flashing or red (depending on
the configuration). If V1 is undershot, the PWR LED extinguishes.

6.4.1 Supply concept
The device is supplied via two separate voltages V1 and V2.
V1 = supply of the module electronics and the respective slots
V2 = supply of module electronics and the respective connectors (separately detachable)
The supply concept enables the safety-related shutdown of parts of the plant via emergency
stop circuits by externally switching off the V2 supply.
