1 Foreword
STOBER drive controllers of the SC6 and SI6 series are available with the Ethernet-based EtherCAT fieldbus system as
standard.
The STOBER product portfolio is also designed for combining these drive controllers with the MC6 motion controller as an
EtherCAT master. Together with the associated AS6 development environment, STOBER gives you a complete and uniform
solution with regard to EtherCAT communication.
Drive controllers of the SC6 and SI6 series successfully passed the EtherCAT as well as Fail Safe over EtherCAT (FSoE)
Conformance Test. There, the communication interface was tested to ensure the reliability and function of the lower-level
communication regardless of vendor.

02/2020 | ID 443025.06
4 Network structure
An EtherCAT network normally consists of an EtherCAT master (controller) and EtherCAT slaves, i.e. drive controllers from
the SC6 or SI6 series in combination with components from third-party manufacturers. The SI6 drive controllers also require
at least one PS6 supply module as an energy supply.
The EtherCAT network structure is generally optimized for a line topology. Each EtherCAT slave has an incoming and
continuing bus connection.
Overall network expansion is virtually unlimited because a maximum of 65535 EtherCAT nodes can be connected together.
You can configure and parameterize the drive controllers using the STOBER DriveControlSuite DS6 software and the entire
EtherCAT network using the STOBER AS6 AutomationControlSuite development environment, for instance.
The following graphic provides a generalized depiction of an EtherCAT network with an EtherCAT master and EtherCAT
slaves, using the SI6 series as an example.

5 Connection
In order to connect drive controllers of the SC6 and SI6 series to other EtherCAT nodes, the top of each device features two
RJ-45 sockets.
5.1 Selecting suitable lines
EtherCAT is an Ethernet-based communications technology optimized for automation technology.
Ethernet patch cables or crossover cables meeting the CAT 5e quality level are the ideal cables. The Fast Ethernet
technology allows a maximum cable length of 100m between two nodes.
Information
Ensure that you only use shielded cables with an SF/FTP, S/FTP or SF/UTP design.
5.2 X200, X201: Fieldbus connection
The drive controllers have both RJ-45 sockets X200 and X201. The sockets are located on top of the device. The associated
pin assignment and color coding correspond to the EIA/TIA-T568B standard.

6.2.3 Parameter types
The following types of parameters are differentiated.
§Simple parameters
Consist of one group and one line with a defined value.
Example:

§Array parameters
Consist of a group, a line and multiple sequential (listed) elements, which have the same properties but different
values.
Example:
A10 Access level
A10[0] access level: Value = Access level via operating unit
A10[2] access level: Value = Access level via CANopen and EtherCAT
A10[4] access level: Value = Access level via PROFINET
§Structure parameters
Consist of a group, a line and multiple sequential (listed) elements, which can have different properties and different
values.
Example:
A00 Save values
