pythonIoc¶

This module allows an EPICS IOC with Python Device Support to be run from within the Python interpreter. Records can be programmatically created and arbitrary Python code run to updated them and respond to caputs. It supports cothread and asyncio for concurrency.

PyPI	`pip install softioc`
Source code	https://github.com/dls-controls/pythonIoc
Documentation	https://dls-controls.github.io/pythonIoc

A simple example of the use of this library is the following:

# Import the basic framework components.
from softioc import softioc, builder
import cothread

# Set the record prefix
builder.SetDeviceName("MY-DEVICE-PREFIX")

# Create some records
ai = builder.aIn('AI', initial_value=5)
ao = builder.aOut('AO', initial_value=12.45, on_update=lambda v: ai.set(v))

# Boilerplate get the IOC started
builder.LoadDatabase()
softioc.iocInit()

# Start processes required to be run after iocInit
def update():
    while True:
        ai.set(ai.get() + 1)
        cothread.Sleep(1)

cothread.Spawn(update)

# Finally leave the IOC running with an interactive shell.
softioc.interactive_ioc(globals())
