The PLATO mission, part of ESA’s Cosmic Vision program, is expected to be launched by 2026 and will focus on discovering exoplanets from gas giants down to small rocky planets. Equipped with telescopes and cameras, including 24 normal and 2 fast cameras, it mainly aims to find Earth-sized planets in the habitable zone of Sun-type stars. The Data Processing System, comprising DPUs and the ICU, manages payload operations, with an On-Board Control Procedures (OBCP) engine enhancing autonomy and flexibility. Written in OCL, OBCPs are independent procedures loaded into the ICU memory, enabling late-stage modifications and regular re-execution, reducing repetitive uploads and conserving bandwidth. In this paper, we present a brief overview of the OCL (On-Board Command) language and its features, as well as the capabilities and benefits of having OBCPs. We also describe the OBCP flight software environment and the OBCP engine implemented in the ASW, along with the features and capabilities of the OBCP for the PLATO mission.
