Create an ENI File Purpose of the ENI File The ENI file describes the EtherCAT network. This file describes the topology in which all slaves in the network are connected. It also describes which values are exchanged periodically. In addition to the topology, the type of slaves must also be known. The different types of EtherCAT slaves are described in the ESI files.

ecmasterlib Overview The „ecmasterlib“ offers an easy way to use EtherCAT with EEROS or in a standalone project. * EtherCAT stack: The EtherCAT stack from Acontis, see The Acontis EtherCAT Stack. * ecmasterlib: This library provides an easy interface to the EtherCAT stack. The library initializes the stack and takes over the periodic sending and receiving of the data on the bus. It provides the following basic interfaces
