The document outlines an EtherCAT training agenda presented by Mohsen Feiz of ICP DAS USA on February 13, 2015. The training will cover an introduction to EtherCAT, its goals and principles, functionalities, and I/O modules. EtherCAT is a real-time industrial Ethernet technology that can achieve cycle times less than 100 microseconds with low communication jitter and reduced hardware costs. Sample applications demonstrate update times of 256 digital I/O in 11 microseconds and 1000 distributed digital I/O in 30 microseconds. The training will conclude with a Q&A session.

4. Introduction to EtherCAT
Making Data Acquisition Easy
EtherCAT Training | Mohsen Feiz| 2/13/15
• EtherCAT : Ethernet for Control Automation
Technology
• EtherCAT is a real-time Industrial Ethernet
technology originally developed by Beckhoff
Automation
5. The goal of EtherCAT
Making Data Acquisition Easy
EtherCAT Training | Mohsen Feiz| 2/13/15
The goal during development of EtherCAT
• Ethernet for automation applications
require cycle time ≤ 100 µs
• low communication jitter
• Reduced hardware costs.
6. EtherCAT – Self Terminating Ethernet
Making Data Acquisition Easy
EtherCAT Training | Mohsen Feiz| 2/13/15
• EtherCAT is real time down to the I/O level
• No underlying sub-systems any more
• No delays in gateways
• In- and outputs, sensors, actuators, drives,
displays: everything in one system!
Any node that does not detect a next node in the
string automatically terminates the network at that
point.
7. Data Representation
Making Data Acquisition Easy
EtherCAT Training | Mohsen Feiz| 2/13/15
• The Ethernet application layer with the most sophisticated
data representation is CIP
• All Modbus TCP devices represent data as either 16-bit
unsigned registers
• There is little standardization or commonality in Modbus
devices. Each manufacturer develops their own unique
Modbus Register map
• Profinet IO uses a similar data representation to Profibus
• EtherCAT uses a very simple data representation, sort of like
Modbus
• There is a data space, a huge data space, and each device is
allocated a part of that data space
8. EtherCAT is faster
Making Data Acquisition Easy
EtherCAT Training | Mohsen Feiz| 2/13/15
• Transmission Rate:
– 2 x 100 Mbit/s (Fast Ethernet, Full-Duplex)
• Update Times:
– 256 digital I/O in 11 µs
– 1000 digital I/O distributed to 100 nodes in 30 µs = 0.03
ms
– 200 analog I/O (16 bit) in 50 µs, 20 kHz Sampling Rate
– 100 Servo-Axis (each 8 Byte In + Out) in 100 µs = 0.1 ms
– 12000 digital I/O in 350 µs
9. Ethernet „on the fly“
Making Data Acquisition Easy
EtherCAT Training | Mohsen Feiz| 2/13/15
Process data is extracted and inserted on the fly:
– Process data size per slave almost unlimited
(1 Bit…60 Kbyte, if needed using several frames)
– Compilation of process data can change in each cycle, e.g. ultra
short cycle time for axis, and longer cycles for I/O update possible
– in addition asynchronous, event triggered communication
