------------------------------------------------------------------------------- This is the README file of the IgH EtherCAT Master. $Id$ Contents: 1) General Information 2) Requirements 3) Building and Installing 4) Realtime & Tuning 5) License ------------------------------------------------------------------------------- 1) General Information ====================== This is an Open-Source EtherCAT master implementation for Linux 2.6. For more information, see http://etherlab.org or contact Florian Pose Ingenieurgemeinschaft IgH Heinz-Baecker-Str. 34 D-45356 Essen http://igh-essen.com ------------------------------------------------------------------------------- 2) Requirements =============== 1) Software requirements Configured sources for the Linux 2.6 kernel are required to build the EtherCAT master. 2) Hardware requirements The EtherCAT master needs a RTL8139 (or compatible) network interface card to run. Drivers for other widespread devices (i. e. Intel PRO/100) will be implemented soon. ------------------------------------------------------------------------------- 3) Building and installing ========================== 1) Create a copy of the configuration template: $ cp ethercat.conf.tmpl ethercat.conf 2) Adjust the Variables in the configuration file to your needs. 3) Build the EtherCAT master and network device driver modules: $ make 4) Install the the EtherCAT master (as root): # make install This will create the following files and directories: - /etc/sysconfig/ethercat (configuration file) - /etc/init.d/ethercat (startup script) - /usr/sbin/rcethercat (link to startup script) The modules will be placed in /lib/modules//kernel/drivers/net (where is the Linux kernel version configured in ethercat.conf). ------------------------------------------------------------------------------- 4) Realtime & Tuning ==================== Realtime patches for the Linux kernel are supported, but not required. The realtime processing has to be done by the calling module (see API documentation). The EtherCAT master code itself is (except for the free-run mode) completely passive. To avoid frame timeouts, deactivating DMA access for hard drives is recommented (hdparm -d0 ). ------------------------------------------------------------------------------- 5) License ========== Copyright (C) 2006 Florian Pose, Ingenieurgemeinschaft IgH This file is part of the IgH EtherCAT Master.
