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 | ||||||
|---|---|---|---|---|---|---|
|
...
| |
$ 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 | ||||||
|---|---|---|---|---|---|---|
| ||||||
$ 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.
It is good practice to exit all environments before activating the desired environment in order to avoid problems.
| Code Block | ||||
|---|---|---|---|---|
| ||||
$ 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.
