Subject: Re: [Emc-users] Using Ethernet to communicate with components
Hi Igor
I thought of that, too. you can use Ethernet/IP or EtherCat.
On the other site there is CAN-BUS (non-tcp)
Just sitting on my table desk I have a setup running with Beckhoff EtherCat(TM)
components. I bought their thesting kit and got it to work with emc.
it runs with etherlab on top of rtai and I have adapted the glue code to create
the i/o-pins for the componbents. You need one of the compartible ethernet
chipsets (intel or realtek) to have a realtime driver.
You can even drive their motor controllers directly by providing a position
signal.
Prices may vary, but to get an impression:
Testing kit (bus interface, 2x4I,2x4O) is around €200, a 32bit incremental
encoder input is €188, 8 digital-I are €35, 8 digital-O are €39, 2 analog-O
16bit €145, a 4 axis motor interface
(4x16bit-incs&4x+/-10V-analog&16xI-digital,16xO-digital,plugs) is €510.
I will set up a wiki page with more info soon.
bye

I think that the trend in industrial machines, is to use Ethernet as
much as possible inside industrial machines. On the surface, it
appears to be a very attractive option, with all devices hooked up to
the network switch and communicating seamlessly, without the mess of
wires. What are the implications of this for EMC?

BTW we should have Ethercat interfaced Anything I/O card out fairly soon. (The
7I62) it has 96 I/O. We have it (barely) working on the bench. We are hoping
to be able to support HostMot2 firmware with relatively minor driver changes
to the HostMot2 driver.
