Hi Mark,
The simple inexpensive setup, one needs the EtherCAT Master and the
EtherCAT Slave
1) EtherCAT Master : There are three different versions, which ESS is
facing currently 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
2) HW list
* EK1100 EtherCAT Coupler (EtherCAT Terminals EL/ESxxxx)
* Some modules AI/AO and so on
* EL9011 Bus end cap
You need a PC have two Ethernet interfaces.
3) EPICS EtherCAT Driver and DB
3.1) Diamond https://github.com/dls-controls/ethercat
3.2) PSI https://github.com/paulscherrerinstitute/ecat2
3.2*) ESS https://github.com/icshwi/m-epics-ecat2 (old forked
version of PSI)
3.2 and 3.2* need the ecat2db files such as
https://github.com/icshwi/e3-ecat2db
You can select HW (Slave) list based on ecat2db files if you want to
try them.
Well, it is not the perfect condition in terms of many issues for the
future. We are trying to find a way in order to minimize risks in the
future now.
HTH,
Han
P.S. I enclosed the file, which I built for the 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
