As with all Python projects, it is good practice to create a development environment in which to install all the libraries necessary for testing:

Code Block
languagebash
themeConfluence
titleProcedure

...

for CONDA Environment
$ conda create --name <name_of_environment> python=3.8.13

...


$ conda

...

 activate <name_of_environment>
$ pip install cothread==2.20.0

...


$

...

 pip install softioc==4.5.0

This is the minimal environment for operating a SoftIOC in Python.


It is not possible o use cothread in Windows. In this case it is necessary to use asyncio:

Code Block
languagebash
themeConfluence
titleInstalling asyncio instead of cothread in Windows
$ pip install asyncio==3.4.3

See https://dls-controls.github.io/pythonSoftIOC/master/how-to/use-asyncio-in-an-ioc.html for an example of softIOC running with asyncio.


warning It is good practice to exit all environments before activating the desired environment in order to avoid problems.

Code Block
languagebash
themeConfluence
$ conda deactivate
$ conda activate <name_of_environment>

Test SoftIOC with CS-Studio

To do tests on the IOC you can either use the terminal from which the IOC itself was launched, or you can use CS-Studio Phoebus.

1.Terminal

Code Block
languagebash
themeConfluence
(epics) $ python test.py
