Yeah the last ethernet switches I tested measured 4-7us for cut-through operation with Gigabit packets. I don't think EtherCAT's advantages are so obvious compared to Ethernet especially if you use a layer 2 addressing scheme rather than TCP.
excellent introduction on Ethercat, especially for me who comes with "IT"/Communication backgroud. speaking about Ferrari, love German guys of making a joke as seriously as telling a truth
What most interesting is etherCAT has two different protocols which share the same lower layers, enables two different mode to run faster mode and conventional TCP/IP mode. Since TCP/IP tools are widely used already so it will greatly contribute lower manufacture cost. Geneous!
Over the last year, I've been debating whether I should make the move over to EtherCAT from EIP. A few years after this presentation, and there's now a lot of devices compatible with EtherCAT -- making the switch a lot more painless than it would have been back then. I think it's time for me to "switch" over. This post brought to you by an integrator who's crazy tired of Rockwell Automation software's insane pricing structure.
Thanks for sharing your experience, @miguelzavaleta1911! You can find more than 1300 EtherCAT product entries in the official EtherCAT Product Guide at www.ethercat.org/en/products.html.
Great presentation, I watched to learn the basics and left wanting to implement it on every system I work on :'). I think I get what you are saying about topology and EtherCAT existing "below" Ethernet but seems to good to be true. If i have a ring setup with say EtherCAT Master Port 1>Ethernet IP router P1>Ethernet IP router P2>Stepper drive P1>Stepper Drive P2>EtherCAT master Port 2 will that work?
EtherCAT is a network where you can use one EtherCAT master at a time only. So the network you've described will not work. Please get in contact with techinfo@ethercat.org and let us know your requirements in more detail.
@DevinBillings: It depends on the amount of process data to fit in the payload part (= EtherCAT telegram, which consists of one to n Datagrams) of an Ethernet frame according to the IEEE 802.3. In a bigger EtherCAT network, the MainDevice might need to send out several frames. Reference: www.ethercat.org/en/technology.html#1.1
Modern Ethernet switches have port to port latency of single digit nanoseconds and are non-blocking. Arista has one with less than 4ns of latency. TCP/IP has been hardware accelerated for a very long time. What advantage does EtherCAT have over that? 30microseconds is 7500 times longer than 4ns. Ethernet switches are NOT synchronous devices with a cycle time. They process frames asynchronously as they are received.
Really great presentation. Is there any link where we can access the presentation? I searched on your website and I wasn't able to find this presentation. Thanks!
Hi Gerfel, you may have to distinguish between configuring an EtherCAT network (which is very simple, as the master typically assigns the addresses automatically) or implementing EtherCAT into your device and configuring the ESC. If you need some support, please get in contact with us at techinfo@ethercat.org!
@@EtherCATGroup Wow! I really appreciate your reply, thank you. I am relatively new to EtherCAT and slightly acquainted with slave devices, mostly LAN9252. I'll definitly contact if I need some support.
Thank you. It's challenging to include all features of EtherCAT within 20 minutes. :) However, you can find more information about EtherCAT P on www.ethercat.org/ethercat-p.
The yawn when looking at EtherNet/IP's 8ms cycle time was savage! Love it
Modern ethernet switches have as low as 4ns port to port latency.

When the Speaker yawns, everybody yawns.
Great explanation. I love the subtle wit!
Very effective presentation and a great marketing speech. ;-)
I would give it a try on my next plc+motion application.

Great presentation
@EtherCATGroup Do we need to replace the Ethernet communication modules in both PLC rack and I/O rack or only in the I/O rack to adapt EtherCAT?
Great video, simply about complicated!

Love this. This comms protocol kicks VARAN in the teeth.
Great talk! U really raised some interesting points! Thank you
Can we get the PPT ?!
So what if you have 100 devices and you need more than one EtherCAT frame?

At 11:02 "UCP" should probably be "UDP" otherwise a great introduction, also like the idea of not administring any more ip addresses /theitguy

Please write to info@ethercat.org and we'll try to help you.
Great work, I love it :)
I saw what you did there with the yawn. Lol!
I am not sure if it's just me, but configuring EtherCAT is relatively difficult for me. Configuring ESC (EtherCAT Slave Controller), for example.

#Topology Option Is Best For Troubleshooting while EtherCAT Error...
who are the makers of ethercat chips?
HAHA the YAwning XD
EtherCAT is obsolete?
