voltage

The BNI IOL-…serves as a decentralized output module that communicates with a IO-Link

Master. This allows to control various devices.

Attention!

Installation and startup are to be performed only by trained specialists. Qualified

personnel are persons who are familiar with the installation and operation of the

product, and who fulfills the qualifications required for this activity. Any damage

resulting from unauthorized manipulation or improper use voids the

manufacturer's guarantee and warranty. The Operator is responsible for

ensuring that applicable of safety and accident prevention regulations are

complied with.

Commissioning and inspection

The operating company shall be responsible for observance of locally applicable safety

instructions.

Before commissioning, carefully read the operating manual.

The system must not be used in applications in which the safety of persons is dependent on

the function of the device.

Authorized Personnel

Installation and commissioning may only be performed by trained specialist 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 operating

manual

Obligations of the Operating Company

The device is a piece of equipment from EMC Class A. Such equipment may generate RF

noise. The operator must take appropriate precautionary measures. The device may only be

used with an approved power supply. Only approved cables may be used.

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.

Attention!

The BNI modules always have good chemical and oil resistance. When used in

aggressive media (such as chemicals, oils, lubricants and coolants, each in a

high concentration (i.e. too little water content)), the material must first be

checked for resistance in the particular application. No defect claims may be

asserted in the event of a failure or damage to the BNI modules caused by such

aggressive media.

Attention!

Disconnect all power before servicing equipment.

Note

In the interest of product improvement, the Balluff GmbH reserves the right to

change the specifications of the product and the contents of this manual at any

time without notice.

• The output pins are overcurrent protected.

• Wire length of the I/O < 3m

• Note: According to the IO-Link specification the current at pin 1 is limited to

200mA, this limit also applies for US OUT. If you use Balluff IO-Link Master the

maximum value 1,0 A is possible.

For "772" only Byte 0

The serial number has the default value 16*0x00. To use the master validation mode

"Identity", with this Parameter are set a serial number. This prevents that a Device will be

connected to a wrong master.

5.4. Reset factory

setting

This Device is compatible to IO-Link Master version 1.0 and 1.1 version specific functions

like Data Storage will be supported only in combination with an IO-Link Master accordant to

the IO-Link Version of the function.

Each IO-Link Master of the IO-Link Version 1.1 supports data storage. This can be used to

save the device parameter in the IO-Link Master. In case of a device swap, the saved

device parameter will be transferred to the new device.

This feature allows writing parameters in one block. It´s necessary of one parameter

depends on the other.

The System Command "reset factory settings", resets the device to factory settings. It can be

executed by writing 0x82 to Index 2 subindex 0.

voltage

The BNI IOL-…serves as a decentralized output module that communicates with a IO-Link

Master. This allows to control various devices.

Attention!

Installation and startup are to be performed only by trained specialists. Qualified

personnel are persons who are familiar with the installation and operation of the

product, and who fulfills the qualifications required for this activity. Any damage

resulting from unauthorized manipulation or improper use voids the

manufacturer's guarantee and warranty. The Operator is responsible for

ensuring that applicable of safety and accident prevention regulations are

complied with.

Commissioning and inspection

The operating company shall be responsible for observance of locally applicable safety

instructions.

Before commissioning, carefully read the operating manual.

The system must not be used in applications in which the safety of persons is dependent on

the function of the device.

Authorized Personnel

Installation and commissioning may only be performed by trained specialist 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 operating

manual

Obligations of the Operating Company

The device is a piece of equipment from EMC Class A. Such equipment may generate RF

noise. The operator must take appropriate precautionary measures. The device may only be

used with an approved power supply. Only approved cables may be used.

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.

Attention!

The BNI modules always have good chemical and oil resistance. When used in

aggressive media (such as chemicals, oils, lubricants and coolants, each in a

high concentration (i.e. too little water content)), the material must first be

checked for resistance in the particular application. No defect claims may be

asserted in the event of a failure or damage to the BNI modules caused by such

aggressive media.

Attention!

Disconnect all power before servicing equipment.

Note

In the interest of product improvement, the Balluff GmbH reserves the right to

change the specifications of the product and the contents of this manual at any

time without notice.

• The output pins are overcurrent protected.

• Wire length of the I/O < 3m

• Note: According to the IO-Link specification the current at pin 1 is limited to

200mA, this limit also applies for US OUT. If you use Balluff IO-Link Master the

maximum value 1,0 A is possible.

For "772" only Byte 0

The serial number has the default value 16*0x00. To use the master validation mode

"Identity", with this Parameter are set a serial number. This prevents that a Device will be

connected to a wrong master.

5.2. Data Storage

5.3. Block

parameter

5.4. Reset factory

setting

This Device is compatible to IO-Link Master version 1.0 and 1.1 version specific functions

like Data Storage will be supported only in combination with an IO-Link Master accordant to

the IO-Link Version of the function.

Each IO-Link Master of the IO-Link Version 1.1 supports data storage. This can be used to

save the device parameter in the IO-Link Master. In case of a device swap, the saved

device parameter will be transferred to the new device.

This feature allows writing parameters in one block. It´s necessary of one parameter

depends on the other.

The System Command "reset factory settings", resets the device to factory settings. It can be

executed by writing 0x82 to Index 2 subindex 0.
