The major portions of the work include, but are not limited to: • Develop SCADA/HMI configuration standards. These standards will be used for this project and future District projects. As part of the standards development, collaborate with District staff to review the potential for the use of Situational Awareness (also referred to as High Performance HMI) techniques and alarm management processes to improve the overall HMI system. • Develop PLC Programming Standards. These standards will be used for this project and future District projects. It is intended that converted PLC configurations and programs shall leverage the advanced features and functionalities of the new Logix5000 controllers. • Develop a data migration plan to allow retrieval of existing historical data, as well as the future SCADA data via a single interface. • Finalize the SCADA system architecture to support current operations. A preliminary SCADA system architecture has been developed, please see Appendix A. • Develop a system based on the National Institute of Standards and Technology (NIST) Cybersecurity Framework for the security of industrial control systems, District OT Cybersecurity practices, and industry standard approaches. Third party cyber security penetration tests may be completed by the District to test the security of the operational SCADA system. Any security issues would need to be resolved by the DB Team.
