About this
manual
This manual describes the Balluff IO-Link I/O module, also called a sensor/actuator hub.
The IO-Link protocol is used to link to the higher-level master module.
Functionally this compact, cost-effective module is similar to a passive splitter box; it records
digital sensor signals and transmits them over the IO-Link interface. It passes control signals
coming over IO-Link to the connected actuators.
Structure of the
manual
This guide is arranged so that one chapter builds upon the other.

2Safety
Intended use
The BNI IOL-… acts as a decentralized input/output sensor module, which is connected to a
higher-level IO-Link master module through an IO-Link interface.
Installation and
startup
Attention!
Installation and startup must only be carried out by trained technical personnel.
Qualified personnel are persons who are familiar with installation and operation
of the product and have the necessary qualifications for these tasks.
Any damage resulting from unauthorized tampering or improper use voids the
manufacturer's guarantee and warranty. The operator must ensure that
appropriate safety and accident prevention regulations are observed.
General safety
instructions
Commissioning and inspection
Before commissioning, carefully read the User's Guide.
The system must not be used in applications in which the safety of persons is dependent
upon proper functioning of the device.
Authorized personnel
Installation and startup must only be carried out by trained technical personnel.
Intended use
Warranty and liability claims against the manufacturer are rendered void by:
−Unauthorized tampering
−Improper use
−Use, installation or handling contrary to the instructions provided in this User's
Guide.
Obligations of the operating company
This device meets the specifications for EMC, Category A. It may cause HF noise.
The owner/operator must take appropriate precautionary measures against this for its use.
The device may only be used with an approved power supply. Use only approved cables.
Malfunctions
In the event of defects and device malfunctions that cannot be rectified, the device must be
taken out of operation and protected against unauthorized use.
Intended use is ensured only when the housing is fully installed.
Resistance to
aggressive
substances
Attention!
The BNI modules always have good chemical and oil resistance. When using an
aggressive medium (e.g. chemicals, oils, lubricants and coolants in high
concentration (such as with low water content)), the compatibility of the material
with the respective medium must first be tested. No warranty claims will be
honored for faults or damage to the BNI modules caused by the use of
aggressive media.
Dangerous
voltage
Attention!
Before maintenance, disconnect the device from the power supply.
Note
In the interests of product improvement, Balluff GmbH reserves the right to
change the technical data of the product and the content of this manual at any
time without notice.

Power supply
Three different types of connection are used for supplying the module (US1), the sensors (US2)
and the actuators (UA). The following connections are available depending on the device type:

3First steps
Mechanical
connection
The BNI IOL modules are attached using 2 M6 screws and 2 washers.
Electrical
connection
The BNI IOL-... modules do not require their own supply voltage. Supply voltage is provided
via the IO-Link interface and the higher-level IO-Link master module. You can however use
an additional AUX terminal for supplying the sensors and actuators connected to the module.
The connections are described in the previous section.
Function ground
The modules are equipped with a ground connection (FE).
Fig. 3.2: FE connection
➢Connect the sensor hub module to the ground connection.
Note
The FE-connection from the housing to the machine must have low impedance
and be as short as possible.
IO-Link
connection
The IO-Link connection is established via an M12 connector (A-coded, male).
This connection is used for supplying the module. For some devices this terminal is also
used for powering the sensors and/or actuators connected to the module.
IO-Link (M12, A-coded, male)
Pin
Requirements
1
Supply voltage for module (US1), +24 V, max. 4 A
2
Supply voltage for actuators (UA), +24 V, max. 4 A
3
GND, reference potential
4
C/Q, IO-Link data transmission channel
Attention!
Overcurrent. Defective or missing fuses in the voltage supply for the sensor and
actuator will result in damage to them. Use a fuse or an intelligent power supply
(current monitoring designed for maximum 4 A) which turns off power when
overcurrent is present.
Connecting the
sensor hub
➢Connect ground conductor to the function ground connection, if available.
➢Connect the incoming IO-Link cable to the sensor hub.
Note
A standardized sensor cable is used to connect to the higher-level IO-Link master
module. Maximum length of 20 m.

16 digital inputs/outputs with single-channel monitoring, IO-
Link V1.1 with extension port
Extension port
These modules use port 7 in various ways. By default, it is used as a digital I/O slot, where
both pin 2 and pin 4 can be used as a digital input or output.
This slot can be used as an extension port by making a corresponding entry in the
parameter with an index of 55hex. This makes it possible to use port 7 for one of the
following connected modules:
-Device only
-With identical device version
-With 22/24 valve interface

The device connected to the extension port is referred to in the user's guide as the "second
device".
Note
The command for resetting to factory defaults (Factory reset) has no effect on the
configuration of the extension port.
Note
The process data length depends on the configuration.
The extension port can be configured using parameter 0x55. If data storage or validation is
used, configuration for validation must follow (compatible). Depending on the system the
device code may need to be entered (parameter data table) or the device code read from the
IODD.

Data handling
with extension
port
If the extension port is enabled, the contents and length of the process data (or ISDU) are
calculated as a unification of the process data (or ISDU) provided by both parties.
PD result = PD of the first device + PD of the second device
ISDU result = ISDU of the first device + ISDU of the second device
The + operation adds the second device.

Setting the
serial number
54hex
The serial number has a factory set value consisting of 16 ASCII characters, e.g. 0E-G550389-
1D-26. The serial number of the unit cannot be changed. For reasons of compatibility this
parameter can be used to assign a custom serial number.
Note
The command for resetting to factory defaults (Factory reset) resets the serial number
to the factory set value.
