Firmware and hardware versions
This documentation refers to the firmware and hardware version that was applicable at the time the
documentation was written.
The module features are continuously improved and developed further. Modules having earlier production
statuses cannot have the same properties as modules with the latest status. However, existing properties
are retained and are not changed, so that older modules can always be replaced with new ones.
The firmware and hardware version (delivery state) can be found in the batch number (D-number) printed on
the side of the EtherCAT Box.
Syntax of the batch number (D number)
D: WW YY FF HH
WW - week of production (calendar week)
YY - year of production
FF - firmware version
HH - hardware version
Example with D No. 29 10 02 01:
29 - week of production 29
10 - year of production 2010
02 - firmware version 02
01 - hardware version 01
Beckhoff Identification Code (BIC)
The Beckhoff Identification Code contains additional information about the delivery state of the module:

2 Product overview
2.1 Product group: EtherCAT Box Modules
EtherCAT Box modules are I/O modules for industrial controllers.
They comply with protection class IP67 and are intended for use outside the control cabinet in wet, dirty or
dusty industrial environments.
EtherCAT Box modules communicate with the controller via the EtherCAT fieldbus. They each have two
connections for EtherCAT communication and for the power supply:
• Feed
• Downstream connection
This enables the cabling of EtherCAT Box modules in a line structure:

IO-Link master
The EP6224 IO-Link module enables connection of up to four IO-Link devices, e.g. actuators, sensors or
combinations of both. A point-to-point connection is used between the terminal and the device. The terminal
is parameterised via the EtherCAT master. IO-Link is designed as an intelligent link between the fieldbus
level and the sensor, wherein parameterisation information can be exchanged bidirectionally via the IO-Link
connection. The parameterisation of the IO-Link devices with service data can be done from TwinCAT via
ADS or very conveniently via the integrated IO-Link configuration tool.
Product overview
EP6224 and EP6228 11Version: 1.5
In the standard setting, the EP6224 functions as a 4-channel input terminal, 24 V DC, which communicates
with connected IO-Link devices, parameterises them and, if necessary, changes their operating mode.

IO-Link master
The EP6228 IO-Link module enables connection of up to eight IO-Link devices, e.g. IO-Link box modules,
actuators, sensors or combinations thereof. A point-to-point connection is used between the module and the
device. The terminal is parameterised via the EtherCAT master. IO-Link is designed as an intelligent link
between the fieldbus level and the sensor, wherein parameterisation information can be exchanged
bidirectionally via the IO-Link connection. The parameterisation of the IO-Link devices with service data can
be done from TwinCAT via ADS or very conveniently via the integrated IO-Link configuration tool.
In the standard setting, the EP6228 functions as a 8-channel input terminal, 24VDC, which communicates
with connected IO-Link devices, parameterises them and, if necessary, changes their operating mode.

3 IO-Link master principles
3.1 Topology
The IO-Link master serves as a gateway between an automation system (EtherCAT) and the IO-Link
devices. It has several IO-Link ports, to each of which an IO-Link device can be connected.

3.2 Ports
Two classes of IO-Link ports are defined in the IO-Link specification:
Class A ports
Class A ports are intended for the connection of IO-Link devices of the type sensor.
Contacts of a class A port:
• Supply voltage for the IO-Link device: L+, L-
• Data cable for serial communication or switching signals: C/Q
• Data cable for switching signals (optional): DI/DQ
Class B ports
Class B ports are intended for the connection of IO-Link devices of the type actuator.
Contacts of a class B port:
• Two electrically isolated supply voltages for the IO-Link device:
◦ Sensor/logic supply: L+, L-
◦ Actuator supply: P24, N24
• Data cable for serial communication or switching signals: C/Q
