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!
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.
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.
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!
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.
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.
