Hi Mark,

 Sorry for the duplicated and not-ready-to-be-email, I hit the wrong

button.

 For the simple inexpensive setup, one needs the EtherCAT Master, the

EtherCAT Slave, and some HW as follows:

 1) EtherCAT Master : There are three different versions due to many

other reasons. In order to configure the the master, please look at my

ugly script repo :

    https://github.com/jeonghanlee/ecat_setup

 I think, you can find three repositories. If you have any issue to

access any of them, please let me know. And if you know better one,

please let me know.

  2) HW list

   * EK1100	EtherCAT Coupler (EtherCAT Terminals EL/ESxxxx)

 * Some modules AI/AO and so on (depends on your selection for EPICS

EtherCAT driver&DB, please look at 3)

   * EL9011	Bus end cap

   In addition, you need a PC has two Ethernet interfaces.

  3)  EPICS EtherCAT Driver and DB

   3.1) Diamond  https://github.com/dls-controls/ethercat

 : It has DB and Driver. And DB files help you which HW you can

buy)

   3.2) PSI  https://github.com/paulscherrerinstitute/ecat2

 3.2*) ESS https://github.com/icshwi/m-epics-ecat2 (old forked

version of PSI)

 : They do not have DB files, so you need another DB files for

this. Please look at

https://github.com/icshwi/e3-ecat2db/tree/master/ecat2db, then you can

find which HW can be used without writing any codes)

 Well, it is not the perfect condition in terms of many issues. We

(ESS) are trying to find a way in order to minimize risks in the future.

   HTH,
   Han

P.S. I enclosed the photo of a EtherCAT test setup, which I built with

my colleague in our lab.

I am interested in trying out EtherCAT with a simple inexpensive setup.

What are the minimum parts I need to buy if I want to use the EPICS

EtherCAT driver to control some digital I/O, analog I/O, and a stepper

motor?  I looked at the Beckhoff website, but I find it overwhelming.

Thanks,

Mark
