EPICS (Experimental Physics and Industrial Control System) is a set of Open Source software tools, libraries and applications developed collaboratively and used worldwide to create distributed soft real-time control systems for scientific instruments such as a particle accelerators, telescopes and other large scientific experiments.
Client software (EPICS Channel Access Client), which requests access to a Process Variable, runs on the Host PC and is connected to the system via TCP/IP.
