Hello,
I have just started working on an update of the control system
software for an accelerator.
I am still trying out different configurations and learning how to
use EPICS. I followed the tutorial of the EPICS documentation so I
know basic information about IOCs and have common support modules
installed (asyn, calc, streamDevice,...)
I would like to communicate with Beckhoff I/O terminals, both as a
way to learn EPICS and to try out configurations for the final
project. I have tried following this
advice from a previous tech-talk question from 2018.
So far I have installed etherlab's
ethercat master and I've tried installing PSI's ecmc which
needs e3 to build.
Unfortunately, e3-build fails to install epics base so I didn't
get very far...I am on ubuntu which might be the problem.
My questions :
1. Are there maintained EPICS drivers for communicating with
Beckhoff I/O ?
1.a. If so, is ecmc a good option ? (As it depends on e3, meant to run on centOS which is obsolete)
1.b. Are there other similar alternatives ?
2. Should I basically write my own drivers ?
1.a. An advice / general approach for me to follow as I am
new to EPICS ?
Thanks,
Sibylle
