1.3 Introduction to EtherCAT
As far as real-time Ethernet systems are concerned, EtherCAT has become well es-
tablished in the area of automation. The decisive factor here is not only the IEEE802.3/
100BaseTX Ethernet physics known in the home office area, but also the excellent value
for money with regard to implementation in the master and slave modules.
Interconnection can be optionally executed in a star, ring or line structure using standard
patch or crossover cables and is therefore easily adapted to the machine infrastructure.
To reduce the amount of training required, familiar communication and device profiles
were used as of the application layer. In this way, users familiar with CANopen profiles
such as CiA DS301 or DSP402 can change over to this new field bus technology with
minimal training.
In ServoOne we have combined all our past experiences in the CANopen area with this
new field bus technology and achieved maximum compatibility and functionality.
1.4 System requirements
It is assumed you have a standard CANopen setup program and a CANopen interface
driver.
For the precise protocol definitions refer to the CAL specification.
With the aid of these objects it is possible to configure the actual CANopen communica-
tion very flexibly and adapt it to the specific needs of the user.
