Hi Jeremy, Alexis, We currently have two solutions for the EPICS communication layer. ISIS is using a library from LIGO called
tcIoc
(https://git.ligo.org/cds/tcIoc)
and ESS/JCNS are investigating using an interface from FRM called PILS (https://forge.frm2.tum.de/public/doc/plc/master/singlehtml/index.html). Please get in touch if you are interested in joining the collaboration or would like to know more. ISIS Neutron and Muon Source From: Tech-talk <[email protected]>
On Behalf Of GAGET Alexis via Tech-talk Hi Jeremy, Congrats on your work Using the EK9000 for our development we are very interested, I will look into your code maybe next week. For the motion terminals, I have tested myself without success (the motor moved, but not in the way I wanted and I suppose nobody want that way...) The Beckhoff support (the french one) directed me to the p53 of the EK9000 manual "I would like to operate the drive terminals/drives
on the EK9000. Is that possible? No, use a CX with a suitable performance for this, e.g. CX9020 or higher."
So for now we are using the CX8190 and TwinCAT, I'm able to control variable I've mapped throught Modbus using their ModbusServer Functions (TF6250
| TC3 Modbus TCP) Finally we are happy with that solution, we let the process (motor, interlock..etc) in the CX and use EPICS just for configuration and to monitor information. Cheers Alexis GAGET CEA Saclay

de la part de Lorelli, Jeremy J via Tech-talk [[email protected]] Hello everyone, As my summer internship project I've been working on device support for the Beckhoff EK9000, and it's finally ready to be released. You can find the github page here:
https://github.com/slaclab/EK9000
The module requires Modbus R3-0 at least to function, and was built and tested on EPICS R3-14, but it should work well on later versions too. As of right now the module only supports EL10xx, EL11xx, El20xx, EL21xx, EL30xx, EL31xx, EL40xx and EL41xx terminals. Support for motor terminals is currently being worked on, but
won't arrive for at least a couple of months. If you would like support for another terminal type, I'd be happy to implement it. There isn't a
ton of documentation, but I've provided both sample IOC setup and small manual in the repository. If you find any bugs or have any issues, please let me know via email or through an issue on the github repository. Feedback is always welcome! Cheers, Jeremy Lorelli |
