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.

FEATURES:

It complies with the POWERLINK specification DS 301, version 1.1.0.
Data link layer and NMT state machine for Controlled and Managing Nodes
SDO via UDP and EPL ASnd frames
Dynamic PDO mapping
User-configurable object dictionary
Supports the EPL cycle features async-only CN and multiplexed CN
Implemented in plain ANSI C
Modular software structure for simple portability to different target platforms
Supports target platforms with and without operating system
Event driven Communication Abstraction Layer
Provides Generic API for user-application
