■
Overview
CANopen is a communication protocol based on CAN physical
characteristics, which is predominantly used in the automation
industry and for networking within complex devices. Originally
conceived as a fieldbus for networking devices in motion control
applications such as handling systems, CANopen has since es-
tablished itself in the field of medical engineering, vehicle auto-
mation, rail and ship networking as well as building automation.
Interoperability of CANopen is ensured through the use of appli-
cation and device profiles, whereby the wide range of options of-
fered by the bus specification enables an appropriate, precise
selection to be made for the application or device in question.
Furthermore, inverters with CANopen support the "CiA 402
Electrical Drives" device profile.

Overview
Ethernet Industrial Protocol (EtherNet/IP) is an open standard for
industrial networks. EtherNet/IP is used to transmit cyclic I/O
data and acyclic parameter data. EtherNet/IP was developed by
Rockwell Automation and the ODVA (Open DeviceNet Vendor
Association), and belongs to the standardized international
standard series IEC 61158. EtherNet/IP is a popular communica-
tion standard, particularly in the American market and in the
Rockwell controllers environment.
