but EPICS was selected for the PIP2...
The current AWA control and data acquisition system is a completely homebrewed system. It has been functioning well but it is becoming an obstacle of collaborations and future growing. To facilitate collaborations and future growing, it is strongly desired that we upgrade or transform AWA control and data acquisition system into an EPICS based system. An overview of AWA control and data...
Software used in the laboratory very often belongs to the mission-critical group and cannot be updated at any time. Time constraints make software updates stressful, and the lack of tools supporting developers extends the whole process. This has been recognised in the modern environments, but often update of the whole environment is not possible.
Pros and cons of the environment transition...
