IO-LINK INTERFACE
4. IO-Link Interface
IO-Link is a point-to-point communication link between a master device and sensor. Use IO-Link to parameterize sensors and transmit process
data automatically.
For the latest IO-Link protocol and specifications, see www.io-link.com.
Each IO-Link device has an IODD (IO Device Description) file that contains information about the manufacturer, article number, functionality etc.
This information can be easily read and processed by the user. Each device can be unambiguously identified via the IODD as well as via an
internal device ID. Download the Q5X's IO-Link IODD package (p/n 215345) from Banner Engineering's website at www.bannerengineering.com.
Banner has also developed Add On Instruction (AOI) files to simplify ease-of-use between the Q5X, multiple third-party vendors' IO-Link masters,
and the Logix Designer software package for Rockwell Automation PLCs. Three types of AOI files for Rockwell Allen-Bradley PLCs are listed
below. These files and more information can be found at www.bannerengineering.com.
Process Data AOIs—These files can be used alone, without the need for any other IO-Link AOIs. The job of a Process Data AOI is to intelligently
parse out the Process Data word(s) in separate pieces of information. All that is required to make use of this AOI is an EtherNet/IP connection
to the IO-Link Master and knowledge of where the Process Data registers are located for each port.
Parameter Data AOIs—These files require the use of an associated IO-Link Master AOI. The job of a Parameter Data AOI, when working in
conjunction with the IO-Link Master AOI, is to provide quasi-realtime read/write access to all IO-Link parameter data in the sensor. Each Param-
eter Data AOI is specific to a given sensor or device.
IO-Link Master AOIs—These files require the use of one or more associated Parameter Data AOIs. The job of an IO-Link Master AOI is to trans-
late the desired IO-Link read/write requests, made by the Parameter Data AOI, into the format a specific IO-Link Master requires. Each IO-Link
Master AOI is customized for a given brand of IO-Link Master.
Add and configure the relevant Banner IO-Link Master AOI in your ladder logic program first; then add and configure Banner IO-Link Device AOIs
as desired, linking them to the Master AOI as shown in the relevant AOI documentation.
