IO-Link box with four configurable analog differential inputs
The EP3174-0002 and ERI3174-0002 IO-Link boxes have four analog inputs which can be individually
parameterized, so that they process signals either in the -10V to +10V range or the 0/4mA…20mA range.
The voltage or input current is digitized with a resolution of 16bits, and is transmitted (electrically isolated) to
the higher-level automation device.
The four input channels have differential inputs and possess a common, internal ground potential. The input
filter and therefore the conversion times are configurable in a wide range. The inputs can, if required, be
scaled differently, and automatic limit value monitoring is also available. Parameterization is done via IOLink. The parameters are stored in the module.
The IO-Link box modules with die-cast zinc housing (ERI series) can be used in extremely challenging
industrial and process environments. The fully sealed design and the metal surface of the ERI series make it
ideal for applications requiring enhanced load capacity and protection against welding spatter, for example.

IO-Link basics
3 IO-Link basics
IO-Link represents a communication system for the connection of intelligent sensors and actuators to an
automation system in the IEC61131-9 standard under the designation "Single-drop digital communication
interface for small sensors and actuators" (SDCI).
The electrical connection data and the communication protocol are standardized and summarized in the IO-
Link specification.
IO-Link specification
The development of the EP6224-xxxxxx was based on IO-Link specification 1.1. At the time of the
preparation of this documentation, the IO-Link specification is entering the IEC standardization and
will be adopted in extended form as IEC61131-9. The new designation SDCI will be introduced at
the same time. As a member of the respective committee, Beckhoff supports the development of
IO-Link and reflects changes to the specification in its products.
3.1 IO-Link system configuration
An IO-Link system consists of an IO-Link master, one or more IO-Link devices and sensors or actuators. The
IO-Link master provides the interface to the higher-level controller and controls the communication with the
connected IO-Link devices. The EP6224-xxxx IO-Link master module from Beckhoff has four IO-Link ports,
each of which can be connected to an IO-Link-Device. IO-Link is therefore not a fieldbus, but a peer-to-peer
connection (see figure below).
EPI3xxx, ERI3xxx 11Version: 1.2
IO-Link basics
Fig.3: IO-Link overview: Peer-to-peer communication
EPI3xxx, ERI3xxx12 Version: 1.2
IO-Link basics
The connected IO-Link devices have individual parameter information, which is detected during automatic
scanning with TwinCAT and transferred to the System Manager (see chapter "Basic function principles",
integration of IO-Link devices). Module-specific information can be imported offline in the form of an IO-Link
Device Description (IODD) and transferred to TwinCAT.
• How to manually configure (physically non-existent) IO-Link masters and devices in TwinCAT is
described under the following two links: Offline configuration settings - TwinCAT (master) [}26], 1.
Importing the device description IODD [}53]
• How to configure physically existent IO-Link masters and devices in TwinCAT is described under the
following two links: Online configuration settings - TwinCAT (master) [}32], 2. Automatic scanning of
the IO-Link ports [}56]
3.2 Establishment of IO-Link communication
Establishment of IO-Link communication
The establishment of the IO-Link communication is illustrated in Fig. Establishment of IO-Link
communication. This illustrates in particular the sequence when automatically scanning [}56] the IO-Link
port.
Fig.4: Establishment of IO-Link communication
• If an IO-Link device is connected to a master port, the master attempts to establish communication. A
defined signal level, the WakeUp pulse, signals to the slave that UART bytes are to be sent from now
on.
From this point on, all data will be interpreted by the IO-Link slave as UART bytes.
• The master runs through all baud rates [}15], starting with the fastest baud rate (COM3 = 230
kbaud). A successful connection has been established when the slave responds to the WakeUp pulse.
• First of all the master reads the basic parameters (Vendor ID, Device ID, process data length,
telegram type and cycle time) and compares them with the existing configuration.
EPI3xxx, ERI3xxx 13Version: 1.2
IO-Link basics
• If no connection could be established to the slave, or if the saved parameters differ from those read,
the corresponding error is output.
• If the saved parameters differ from those read, the IO-Link device changes to the PREOP state.
If the IO-Link device specification is V1.1, the parameter server [}14] is now executed. If the IO-Link
device specification is V1.0, this step is omitted and the device changes directly to OP.
• Finally the cycle time is written and the device changes to OP. After that the master cyclically
exchanges data with the slave.
3.3 Device description IODD
IO-Link devices possess individual system information in the form of an IO device description (IODD), which
contains:
• Communication features
• Device parameters with value range and default values
• Identification, process and diagnostic data
• Device data
• Text description
• Picture of the device
• Vendor's logo
If the IODD is imported, then the device data are automatically detected during automatic scanning [}56]
with TwinCAT and adopted in the System Manager (cf. integration of the IO-Link devices).
3.4 Parameter server
In order to be able to use the functionality of the parameter server, both the IO-Link master and the IO-Link
device must be specified to V1.1. The IO-Link revision of the device can be read for the individual port under
Settings [}62]. The Beckhoff IO-Link master supports specification V1.1 from FW 07.
• The parameter server in the IO-Link master contains parameter data that are saved in the IO-Link
device. The memory capacity is max. 2kbyte (including header).
If the IO-Link-Device is exchanged, then the data are loaded from the parameter server into the new
device. The requirement for this is that the device is of the same type (VendorID & DeviceID must be
the same).
• If a new IO-Link-Device is configured, then the IO-Link master loads the parameters from the IO-LinkDevice into the parameter server when starting for the first time.
Data from other IO-Link devices that are already configured (VendorID & DeviceID do not correspond
to the configured device) are overwritten.
• At each further start the IO-Link master uses a checksum to check whether the data in the parameter
server correspond to those on the IO-Link-Device and if necessary downloads them to the device.
• If the parameters change during the device runtime, this can be reported via the Master's special
event. The master then starts the parameter server with an upload.
• By default the event is not set each time the parameters are written, therefore the end of the
parameterization procedure has to be reported to the IO-Link device.
The IO-Link-Device then sends the corresponding event to the master. The data are loaded into the
parameter server.
• In the case of a pre-programmed IO-Link-Device, no download takes place from the parameter server
to the device.

IO-Link basics
3.5 Data transfer rate
An IO-Link master according to specification V1.1 supports all three transmission types and automatically
adjusts the data transfer rate to that of the IO-Link device.
An IO-Link device usually supports only one data transfer rate. IO-Link devices with different data transfer
rate can be connected to the various ports of the master.
• COM1 = 4.8kbaud
• COM2 = 38.4kbaud
• COM3 = 230.4kbaud

5.1 IO-Link master
5.1.1 Offline configuration settings - TwinCAT (master)
In this part of the documentation is the manual configuration of the IO-Link master in TwinCAT described.
Distinction between Online and Offline
The distinction between online and offline refers to the presence of the actual I/O environment (drives,
terminals, box-modules).
• Offline
If the configuration is to be prepared in advance of the system configuration as a programming system,
e.g. on a laptop, this is only possible in “Offline configuration” mode. In this case all components have
to be entered manually in the configuration, e.g. based on the electrical design (as described under 1.
Importing the device description IODD [}53]).
• Online
If the designed control system is already connected to the EtherCAT system and all components are
energized and the infrastructure is ready for operation, the TwinCAT configuration can simply be
generated through “scanning” from the runtime system. This is referred to as online configuration. In
any case, during each startup the EtherCAT master/ IO-Link master checks whether the devices it finds
match the configuration. This test can be parameterized in the extended device settings.
To take advantage of the current features/settings of the master, the latest version of the ESI file should
always be downloaded. Therefore it is necessary to consider the following note first.
Installation of the latest ESI-XML device description
The TwinCAT System Manager needs the device description files for the devices to be used in order to generate the configuration in online or offline mode. The device description is contained in
the so-called ESI files (EtherCAT Slave Information) in XML format. These files can be requested
from the respective manufacturer and are made available for download. The ESI files for Beckhoff
EtherCAT devices are available on the Beckhoff website. The ESI files should be saved in the TwinCAT installation directory (default: C:\TwinCAT\IO\EtherCAT). The files are read (once) when a new
System Manager window is opened. A TwinCAT installation includes the set of Beckhoff ESI files
that was current at the time when the TwinCAT build was created. For TwinCAT 2.11 and higher,
the ESI directory can be uploaded from the System Manager, if the programming PC is connected
to the internet (TwinCAT → EtherCAT-Devices → Update Device Description…) see following figure.

In this section is described, how to configure the IO-Link master in TwinCAT and the integration of IO-Link
devices.
Configuration of the IO-Link master
Configuration of the IO-Link master requires a plug-in, which is usually supplied with the TwinCAT
installation. When the IO-Link master is added to the TwinCAT System Manager (see section Offline [}26] /
Online [}32] configuration settings - TwinCAT (master)) an additional tab called IO-Link is created (see
following figure). If the tab is not displayed, the associated System Manager extension is missing. You can
install it separately. Please contact support [}96].

Fig.29: Update Device Descriptions
The following conditions must be met before a configuration can be set up:
• the real EtherCAT and IO-Link hardware (devices, couplers, drives) must be present and installed
• the master/devices must be connected via EtherCAT cables and IO-Link cables in the same way as
they are intended to be used later
• the devices/modules be connected to the power supply and ready for communication
• TwinCAT must be in CONFIG mode on the target system.
The online scan process consists of:
• detecting the EtherCAT device (Ethernet Port at the IPC)
• detecting the connected EtherCAT devices. This step can be carried out independent of the preceding
step.
• troubleshooting
The scan with existing configuration can also be carried out for comparison.
Detecting/scanning of the EtherCAT device
The online device search can be used if the TwinCAT system is in CONFIG mode (blue TwinCAT icon or
blue indication in the System Manager).
Fig.30: TwinCAT CONFIG mode display
EPI3xxx, ERI3xxx 33Version: 1.2

Online scanning in Config mode
The online search is not available in RUN mode (production operation).
Note the differentiation between TwinCAT programming system and TwinCAT target system. The
TwinCAT icon next to the Windows clock always shows the TwinCAT mode of the local IPC. The
System Manager window shows the TwinCAT state of the target system.
Right-clicking on “I/O Devices” in the configuration tree opens the search dialog.
Fig.31: Scan Devices
This scan mode not only tries to find EtherCAT devices (or Ethernet ports that can be used as such), but
also NOVRAM, fieldbus cards, SMB etc. Not all devices can be found automatically.
Fig.32: note for automatic device scan
Ethernet ports with installed TwinCAT real-time driver are shown as “RT Ethernet” devices. An EtherCAT
frame is sent to these ports for testing purposes. If the scan agent detects from the response that an
EtherCAT slave is connected, the port is shown immediately as an “EtherCAT Device”.

After confirmation with “OK” a device scan is suggested for all selected devices, see following figure.
Detecting/Scanning the EtherCAT devices
Online scan functionality
During a scan the master queries the identity information of the EtherCAT slaves from the slave
EEPROM. The name and revision are used for determining the type. The respective devices are located in the stored ESI data and integrated in the configuration tree in the default state defined
there.
If an EtherCAT device was created in the configuration (manually or through a scan), the I/O field can be
scanned for devices/slaves.
Fig.34: scan query after automatic creation of an EtherCAT device
The configuration has been build and directly shifted into the online state (OPERATIONAL). The EtherCAT
system should then be in a functional cyclic state, as shown in the following figure.
EPI3xxx, ERI3xxx 35Version: 1.2
Commissioning/configuration of IO-Link master/device
Fig.35: online display example
Please note:
• all slaves should be in OP state
• the EtherCAT master should be in “Actual State” OP
• “frames/sec” should match the cycle time taking into account the sent number of frames
• no excessive “LostFrames” or CRC errors should occur
The configuration is now complete. It can be modified as described under the offline procedure.
The connected IO-Link master (EP6224-2022) is displayed in the TwinCAT structure as you can see in the
figure below.
Fig.36: Master display after scan for boxes
Troubleshooting
Various effects may occur during scanning.
• An unknown device is detected, i.e. an EtherCAT slave for which no ESI XML description is available.
In this case the System Manager offers to read any ESI that maybe stored in the device.
EPI3xxx, ERI3xxx36 Version: 1.2
Commissioning/configuration of IO-Link master/device
• Devices are not detected properly
Possible reasons include:
◦ faulty data links, resulting in data loss during the scan
◦ slave has invalid device description
The connections and devices should be checked in a targeted manner, e.g. via the emergency
scan.
Then re-run the scan.
Scan over existing configuration
If a scan is initiated for an existing configuration, the actual I/O environment may match the configuration
exactly or it may differ. This enables the configuration to be compared.
Fig.37: identical configuration
If differences are detected, they are shown in the correction dialog, so that the user can modify the
configuration as required.
Fig.38: correction dialog
It is advisable to tick the “Extended Information” check box to reveal differences in the revision.

configured revision, the slave maybe used provided compatibility issues are taken into account. If the found revision
is lower than the configured revision, it is likely that the slave cannot be used. The found device may not support all
functions that the master expects based on the higher revision number.
EPI3xxx, ERI3xxx 37Version: 1.2
Commissioning/configuration of IO-Link master/device
Device selection based on revision, compatibility
The ESI description also defines the process image, the communication type between master and
slave/device and the device functions, if applicable. The physical device (firmware, if available) has
to support the communication queries/settings of the master. This is backward compatible, i.e.
newer devices (higher revision) should be supported if the EtherCAT master addresses them as an
older revision. The following compatibility rule of thumb is to be assumed for Beckhoff EtherCAT
Terminals/Boxes:
device revision in the system >= device revision in the configuration
This also enables subsequent replacement of devices without changing the configuration (different
specifications are possible for drives). Example: If an EL2521-0025-1018 is specified in the configuration, an EL2521-0025-1019 or higher (-1020, -1021) can be used in practice.
If current ESI descriptions are available in the TwinCAT system, the last revision offered in the selection dialog matches the Beckhoff state of production. It is recommended to use the last device revision when creating a new configuration, if current Beckhoff devices are used in the real application. Older revisions should only be used if older devices from stock are to be used in the application.

Commissioning/configuration of IO-Link master/device
Parameter data exchange
An intelligent IO-Link sensor/actuator (in the previous figure marked "Sensor (IO-Link Device)") can support
parameterization by SPDU (Service Protocol Data Units). The PLC must explicitly query or, when marked as
such, send these acyclic service data.
SPDU access
TwinCAT supports access via ADS and via the EP6224-xxxxxx CoE directory.
The respective parameter is addressed via the so-called SPDU index. The following ranges are available:
Name Index range
System 0x00..0x0F
Identification 0x10..0x1F
Diagnostic 0x20..0x2F
Communication 0x30..0x3F
Preferred Index 0x40..0xFE
Extended Index 0x0100..0x3FFF
the range 0x4000..0xFFFF is reserved
The use of the implementation of these ranges is the responsibility of the sensor/actuator vendor. In the
interest of clarity, only a few possible indices with names are listed here. Please refer to the corresponding
chapter "Object description and parameterization".
Index Name
0010 Vendor Name
0011 Vendor Text
0012 Product Name
0013 Product ID
0015 Serial Number

ADS
Communication relating to IO-Link demand data is initiated via an ADS command. An ADS address always
consists of a NetID and PortNo. TwinCAT forwards an ADS command to the EP6224 Box module via AoE
(ADS over EtherCAT). From where the command is relayed to the IO-Link master section and therefore to
the data channel.
AoE-NetID
The EP6224 is assigned a dedicated AoE-NetID for communication with the IO-Link master section. This is
assigned by the configuration tool (see the figure below).
EPI3xxx, ERI3xxx 49Version: 1.2
Commissioning/configuration of IO-Link master/device
Fig.51: AoE-NetID allocation
PortNo
The individual IO-Link ports for the master are allocated via the port number. The port numbers are allocated
in ascending order from 0x1000. I.e. IO-Link Port1===PortNo 0x1000 and IO-Link Portn===PortNo
0x1000 + n-1.
The following specification applies for the EP6224 (4-port IO-Link master):
IO-Link Port1 === PortNo 0x1000
IO-Link Port2 === PortNo 0x1001
IO-Link Port3 === PortNo 0x1002
IO-Link Port4 === PortNo 0x1003
ADS Indexgroup
As for CoE, the Indexgroup of an ADS command is specified as 0xF302 for the IO link data channel.
ADS Indexoffset
The IO link addressing with index and subindex is coded in the Indexoffset. The Indexoffset has a size of 4
bytes and is subdivided as follows: 2-byte index, 1-byte reserve, 1-byte subindex.
• Example: Indexoffset 0x12340056 corresponds to index 0x1234 and subindex 56

No manual copying of the XML files
Do not copy the files directly into the folder; read them in via Import Devicedescription instead! Important checks will otherwise be bypassed!
The integration of the IODD file should always be the first step, since this enables the breakdown of the
individual process data of the IO-Link devices as well as the display of the parameters.
There are several ways of integrating an IO-Link device:
1. Importing the IODD file (offline & online) via
◦ button Import Devicedescription [}53] (A) or
◦ button IODD Finder [}53] (B)
2. Automatic scanning of the IO-Link ports (online) via
◦ button Scan devices [}56] (C)
3. Manual insertion (offline & online) via
◦ menu Create Device [}59] (D)
Fig.53: Creating IO-Link devices
If the IODD is not available, the IO-Link device should be integrated online by scanning. Manual integration
of the IO-Link devices via Create Device should only be carried out if the IODD of the vendor and the IO-Link
device are not available at the time of project creation.
Configuration of the IO-Link ports as digital inputs/outputs
If the IO-Link port is to be used as a simple digital input or output, the selection "Std-I/O" -> "dig in" or "dig
out" can be made in the IO-Link Device Catalog. After restarting the EtherCAT system or reloading the
configuration in Config mode (F4), the corresponding process data are created.

To remove a previously configured IO-Link device, right-click to open the context menu and select Delete.
After restarting the EtherCAT system or reloading the configuration in Config mode (F4), the already created
process data are removed.
5.3.1.1 1. Importing the device description IODD
Importing the device description simplifies the integration of the IO-Link devices. The individual process data
are broken down, enabling simple parameterization of the sensor. The IODD only needs to be imported
during the initial commissioning of a new IO-Link device. The import is port-independent. Proceed as follows
to import the IODD:
• Button "Import Devicedescription“
◦ Press the Import Devicedescription button in the IO-Link tab
◦ Select the .xml file of the desired sensor.
◦ After pressing the Open button, the imported files are stored in the following folder:
- for TwinCAT 2.x: \TwinCAT\IO\IOLink
- for TwinCAT 3.x: \TwinCAT\3.X\Config\IO\IOLink.
◦ The imported device descriptions are listed in a tree structure in the Catalog field, sorted by
vendor.
No manual copying of the XML files
Do not copy the files directly into the folder; read them in via Import Devicedescription instead! Important checks will otherwise be bypassed!
• Button "IODD Finder“
◦ Press the IODD Finder button in the IO-Link tab
◦ Searching for the desired IO-Link sensor/device by entering them in the search mask; see the
figure below (1)
◦ Selecting the desired IO-Link sensor/device. Move the mouse pointer over the figure of the desired
IO-Link sensor/device. A blue download icon appears, see the following figure (2).
EPI3xxx, ERI3xxx 53Version: 1.2
Commissioning/configuration of IO-Link master/device
Fig.55: IODD Finder, selection and import of the .xml file
◦ After clicking the download symbol, the .xml file of the selected IO-Link sensor/device is imported
and stored in the following folder:
- for TwinCAT 2.x: \TwinCAT\IO\IOLink
- for TwinCAT 3.x: \TwinCAT\3.X\Config\IO\IOLink
◦ When moving the mouse pointer over the IO-Link sensor/device, a green icon now indicates (see
the following figure (3)) that the .xml file already exists.
Fig.56: IODD Finder, display of an already imported device description
◦ The imported device descriptions are listed in a tree structure in the Catalog field of the IO-Link
tab, sorted by vendor.
• Online configuration: once the IO-Link device has been connected, it is automatically detected and
created with the corresponding parameters by pressing the Scan devices button.
If several devices are stored in the IODD file, the first entry is always selected here. Grouping in the
IODD is usually carried out by the vendor if the process data are the same and there are only
mechanical differences (e.g. other material).
• Offline configuration: The Catalog field shows the IO-Link device catalog, which lists the already
imported device descriptions in a tree structure, sorted by vendor. The IO-Link device can be selected
via drag & drop or by right-clicking on the product with "Add to Port n".

Commissioning/configuration of IO-Link master/device
• Restart the EtherCAT system or reload the configuration in Config mode (F4).
• The IO-Link devices are displayed, and the process data are created. If an error is found when
integrating the IO-Link device, e.g. wrong VendorID or no device connected, then this is indicated via
the status of the port (object state Ch.n 0xF100:0n).

5.3.1.2 2. Automatic scanning of the IO-Link ports
This part of the documentation describes the configuration of the physically available IO-Link devices in
TwinCAT.
During automatic scanning of the IO-Link ports, the steps WakeUp pulse, Baud rate setting, Reading of the
communication parameters, plus Parameter server and Cyclic data exchange, if applicable, are performed,
see Establishing the IO-Link communication [}13]. The corresponding IO-Link device must be connected to
the IO-Link port for this.
The connected devices are automatically detected and configured and a search is performed for the
associated IODD.
Finding connected IO-Link devices
The connected IO-Link devices can be found by clicking the Scan devices button (see the following figure
(C)).
Fig.57: Scan devices (C)
The information window lists the connected device for each of the four ports. Only port 2 of the master is
assigned an IO-Link device. Confirm with the OK button.
Fig.58: Information Scan devices
To be able to work with the devices, the button Reload Devices (F4) must be clicked.

5.3.1.3 3. Manual insertion via Create Device
This part of the documentation describes the manual configuration of the IO-Link devices in TwinCAT.
The manual insertion of the IO-Link device should only be carried out if the IODD from the vendor and the
IO-Link device are not available.
The configuration can then be carried out manually. By saving the project, the settings for the individual ports
are saved. The devices that were created are not stored in the Catalog (see the figure below (A)).
• To insert the IO-Link devices manually via Create Device, proceed as follows:
• If the corresponding IODD of the IO-Link device is already present, the corresponding device can be
selected in the catalog (see the diagram below (A)), sorted by the vendor
• If no IODD is available, the device can be manually added. These data are not saved in the catalog
and must be manually entered for each port.
• Right-click on the port to open the context menu (see the figure below (B)) and select Create Device.
• In the Create Device dialog an IO-Link device with the basic communication parameters can be
created. The mandatory fields here are: For Vendor ID, Device ID and process data length see the
figure below (D). The values VendorID and DeviceID can be entered both in hexadecimal notation
(input format: 0xnnnn) and as decimal numbers (nnnn).
The communication parameters to be entered can be found in the information provided by the device
vendor.
• If the IO-Link device version is 1.1, then the parameter server is activated by the selection of the field.
• Restart the EtherCAT system or reload the configuration in Config mode (F4)
Fig.63: Manual creation of an IO-Link device via the "Create Device" dialog (D)
Reading the IODD
Even when manually creating and scanning, the IODD should always be read in as well in order to
display further sensor-specific information.
If the IO-Link device is created manually, some device settings can be implemented in the settings of the IOLink devices (see Settings of the IO-Link devices) [}62]

5.3.2 EPI3xxx, ERI3xxx - Process data
The System Manager shows the EPI3xxx/ERI3xxx process data which are arranged in the tree structure
under the associated Port (A) (in the following example EPI3174-0002 is connected to port 1).
The EPI3174-0002/ERI3174-0002 offer 16-bit status information and the analog value (16 bit) per channel
(B) for transmission.
Fig.64: Default process data of EPI3174-0002
A detailed representation of the structure is obtained by opening the tree structure of the Channel 1 status
(see A in the following figure).
Activation of the Show Sub Variables button (C) displays the detailed view of the different bit meanings (see
B in the following illustration). The plain text display of the bit meanings is particularly helpful not only in
commissioning, but also for linking to the PLC program.
EPI3xxx, ERI3xxx60 Version: 1.2
Commissioning/configuration of IO-Link master/device
Fig.65: Process data of EPI3174-0002 represented with sub variables
By right-clicking on the Status variable in the configuration tree (A), the structure can be opened for linking.
Both the collective name e.g. Channel 1 Status and the individual bit variable e.g. Overrange can be linked,
but not both at the same time.
The bit meaning i.e. offset position can then be taken from the memory assignment display (E) on the basis
of the point notation, also taking into account the variable size (D).
Example:
163.1 means here that the 1st bit (counting method 0, 1, etc.) or 2nd bit (counting method 1, 2, etc.) in the
status word indicates the Overrange. The user requires this information in the PLC if the status word is to be
divided into its bit meanings.

Vendor calibration
The vendor reserves the right to carry out the basic calibration of the terminal/box modules. Therefore, the vendor calibration cannot be changed.
Calculation of process data
The terminal/box continuously logs measured values and stores the raw values of its A/D converter in ADC
raw value object 0x08nE:01. After each logging of the analog signal a correction is calculated via the vendor
calibration values. This is followed (optionally) by user scaling:
YH= (X

Linking in the PLC with 2-bit values
The limit information consists of 2bits. Limitn can be linked to the PLC or a task in the System Manager:
PLC: IEC61131-PLC contains no 2-bit data type that can be linked with this process data directly. In
order to transmit the limit information, therefore, define an input byte, e.g.
Link the limit to an existing variable.
Additional task: 2-bit variables can be created in the System Manager.

5.3.6.5 Filter mode (FIR and IIR), Index 0x0800:06, 0x0800:15
The EPI31xx, ERI31xx and EPI4xxx, ERI4xxx modules are equipped with a digital filter, which, depending on
the setting, can assume the characteristics of:
• a filter with finite impulse response (Finite Impulse Response Filter, FIR filter) or
• a filter with infinite impulse response (Infinite Impulse Response Filter, IIR filter).
The filter is deactivated by default. Please observe the following note regarding activation with index
0x0800:06.
Activation of the filter with index 0x0800:06 and setting of the filter characteristics
via index 0x0800:15
The filter frequencies are set centrally for all channels of the EPI3xxx, ERI31xx / EPI4xxx, ERI4xxx
modules via index 0x0800:15 (channel 1).
• FIR filter
The filter works as a notch filter and determines the conversion time of the module. It is parameterized
via index 0x0800:15. The higher the filter frequency, the faster the conversion time. A 50Hz and a
60Hz filter are available.
Notch filter means that the filter has zeros (notches) in the frequency response at the filter frequency
and multiples thereof, i.e. it attenuates the amplitude at these frequencies.
The FIR filter operates as a non-recursive filter.

50HzFIR > 50dB 22Hz 625µs
60HzFIR > 45dB 26Hz 521µs
• IIR filter
The filter with IIR characteristics is a discrete time, linear, time invariant filter that can be set to eight
levels (level 1 = weak recursive filter, up to level 8 = strong recursive filter).
The IIR can be understood to be a moving average value calculation after a low-pass filter.

Parameter server (data storage)
The IO-Link boxes support the data storage functionality according to protocol revision 1.1. The parameters
0x0018 (application-specific tag) and 0x08n0 (settings) are secured with the IO-Link master. In order to use
this functionality, the IO-Link master must also support it. (e.g. with the Beckhoff EP6224-xxxx IO-Link
master from firmware 10) Changes to these parameters are saved by the IO-Link master and restored when
the box is replace with an identical IO-Link box. How to use the data storage functionality is explained in
chapter EPIxxxx, ERIxxxx - Setting of the IO-Link device parameters [}68].

5.3.9 Firmware update of the IO-Link device
Firmware update only possible with EtherCAT IO-Link master products
The firmware update of the IO-Link device is only possible with the EP6224-xxxx, EP6228-xxxx and
EL6224. A firmware update is not possible with the KL6224.
An update of the box firmware is currently supported via the EP622x-xxxx IO-Link master box and the
TwinCAT System Manager from version 2.11 R3 build 2248 or TwinCAT 3.1 build 4018.
The firmware update is performed directly via the IO-Link interface. To this end the box must be connected
to the EP622x-xxxx and in Operational state. The update is started in the Advanced dialog of the
corresponding IO-Link port (see the two figures below).
1. Select the EP622x-xxxx Box in the System Manager,
2. in the IO-Link tab, right click on the appropriate port
3. open the Settings tab,
4. select the Advanced button
5. Select IO-Link firmware files via the Download button (use the file extension *.efw).
The Firmware Update dialog is only displayed for supported Beckhoff IO-Link devices. Once the *.efw
file has been checked, the firmware update starts automatically. This process must not be interrupted!
After a successful update, the box is automatically restarted and therefore usually does not have to be
de-energized. Device-specific settings (Appl. -Specific Tag, Settings) will not be lost.

Commissioning/configuration of IO-Link master/device
The firmware version that is currently used can be obtained as follows (see the figure below):
1. Select the EP622x-xxxx Box in the System Manager,
2. In the IO-Link tab, right click on the appropriate port
3. open the Parameter tab,
4. select Index 0x017 (firmware version)
5. click the Read button
6. The firmware version is read out and displayed when IO-Link communication to the box is active.
