Create a Publishable IOC

As seen in Creating an IOC, a single Python script can be an IOC. It is also possible (and the most common situation) to have an entire Python module comprising an IOC. This guide explains both, as well as how to publish an IOC within the DLS environment.

Single File IOC

An IOC that is entirely contained within a single Python source file can be used as an IOC inside DLS simply by adding this shebang line:

#!/dls_sw/prod/python3/RHEL7-x86_64/softioc/3.2/prefix/bin/pythonSoftIOC

IOC entry point for a module

If your IOC is more complicated than one file, it is recommended to write a python module (including docs/tests/etc.). The Panda Blocks Client will be an example of this.

Make an IOC publishable at DLS

To make the IOC publishable, a makefile is required:

Makefile

This file is necessary in order to run dls-release.py, and needs to have both install and clean targets, but doesn’t need to actually do anything. Thus the following content for this file is enough:

install:
clean:
