Experimental Physics and Industrial Control System

Hi Mark,

As Torsten and Jeong Han have already said, the Diamond Ethercat EPICS support is available [1], but it does not support motion.

For some digital I/O and analog I/O we would use kit from our supported set [2].

The master in our setup runs on a Dell R310, using Redhat MRG (real time pre-empt rt kernel).
The minimal ethercat kit would be:  EK1100 coupler, EL1014 (digital input), EL3104 (analogue input), EL2024 (digital output), EL4134 (analogue output).

Best regards,

Ronaldo

Hej Mark,
this is what we use for our motion control test/development crates:

# CPU: CX5130
# Configure EL1018 digital input terminal
# Configure EL2808 digital output terminal
# Configure EL5101 incremental encoder terminal, motor 1
# Configure EL5101 incremental encoder terminal, motor 2
# Configure EL9505 Power supply terminal 5V
# Configure EL1252 digital input terminal
# Configure EL7037 stepper drive terminal, motor 1
# Configure EL7037 stepper drive terminal, motor 2

(No analog IO in our motion crates ;-)

No sure if you have access to this page about other terminals for motion:

PS:
As Han Lee pointed out, there are different SW packages:
- Beckhoff TwinCAT
- Linux ("scanner" from DLS and ecat2 from PSI) (but no motion control)
- Linux ECMC from ESS http://icalepcs2017.vrws.de/talks/mocpl05_talk.pdf
And we are happy to help.
