Welcome to the home page of the EPICS Sequencer project.

This project is a component of the Experimental Physics and Industrial Control System (EPICS), a set of tools, libraries and applications developed collaboratively and used worldwide to create distributed soft real-time control systems for large scale scientific instruments.

The State Notation Language (SNL), is a domain specific programming language that smoothly integrates with and depends and builds on EPICS base. This project defines SNL and provides an implementation, consisting of the SNL compiler and runtime system.

The Sequencer is free software, licensed under the EPICS Open License.
