Ethernet POWERLINK is a Real-Time Ethernet field bus system. It is based on the Fast Ethernet Standard IEEE 802.3.

openPOWERLINK is an Open Source Industrial Ethernet stack implementing the POWERLINK protocol for Managing Node (MN, POWERLINK Master) and Controlled Node (CN, POWERLINK Slave). It implements all important features required by modern POWERLINK devices such as Standard, Multiplexed and PollResponse Chaining mode of operation, dynamic and static PDO mapping, SDO via ASnd and SDO via UDP, as well as asynchronous communication via a Virtual Ethernet interface.

Latest stable version: [2.7.1](\ref sect_revision_v2_7_1) Current version: [2.7.1](\ref sect_revision_v2_7_1)

The documentation of the openPOWERLINK protocol stack can be found in the subdirectory "doc". It is written in markdown markup format. The openPOWERLINK software manual can be generated from the markdown documentation and the in-source documentation with the tool Doxygen. Doxygen version 1.8.11 or higher is required.

To generate the software manual:

  > cd doc/software-manual
  > doxygen

The software manual will be created in HTML format under doc/software-manual/html.

The documentation of the latest stack version is also available online on the openPOWERLINK website: http://openpowerlink.sourceforge.net/
