Description
The Operational Sequencer is a software framework developed to automate complex and frequently executed high-level procedures that are essential to the operation of accelerator systems at the European Spallation Source (ESS). By transforming manual control room tasks into predefined sequences, the tool enhances process repeatability, reliability, and safety by reducing human error.
Designed within the ESS Integrated Control System Software group, the sequencer provides a unified architecture for defining, executing, and monitoring operational tasks. It supports multiple task execution types, scalable system design, and an intuitive graphical interface to facilitate operator oversight.
This paper presents the architectural concepts, implementation challenges, and scalability strategies of the Operational Sequencer, as well as lessons learned from its deployment during ESS commissioning. The framework represents a significant step toward efficient and reproducible operations, reducing both operator workload and time-to-beam for scientific experiments.
