Hi,

I added - system "python your-python-file.py &" to my st.cmd file and

when the ioc starts, the python scripts start! Thank you for the

suggestion.

However when I stop the ioc, the python scripts remain running in the

background. How can I get the python scripts to stop when the ioc is

stopped?

Regards,

Another way automatically start the python script with the ioc, simply
add this kind of line at the end of your IOC’s st.cmd:

system "python your-python-file.py &"

However, you need include “system.dbd” in your IOC application. In
your application’s src/Makefile, add this kind of line:

yourIOCApplicationName_DBD += system.dbd

Hi,

"Is there a way to automatically start the python script with the
ioc?"

-> You can simply use procServ as well to execute your python script

Happy new year!

 I am trying to install systemd-softioc (procServ) as outlines here
 https://github.com/NSLS-II/systemd-softioc [1]. I followed the
instructions
 and successfully installed it on my Raspberry Pi. I installed the IOC

 and can manually start the softioc, however I am not able to start
the
 IOC using manage-iocs. I get the following output:

 softioc@raspberrypi:/epics/iocs/testIOC2$ sudo manage-iocs start
 testIOC2
 Starting the IOC 'testIOC2' ...
 Failed to start the IOC 'testIOC2'; type 'sudo journalctl -xe' for
 details.

 Below is my config file and output from the journalctl

 Config
 ---------
 NAME=testIOC2
 PORT=4053
 HOST=raspberrypi
 USER=softioc
 CHDIR="/epics/iocs/testIOC2/iocBoot/ioctestIOC2"

 The softioc testIOC2 contains a few records which get updated from a
 python script. Which brings me to my next questions. Is there a way
to
 automatically start the python script with the ioc?

 Thank you very much for your help,

 Regards
