-Protective Strategies," bullet six states "PPC and Data Acquisition are in Levels 3 and 2." The paragraph below the bulleted items states "EP systems are allocated to the highest level possible while allowing the system to achieve its design or regulatory function." Please define the abbreviation "PPC", identify what type of device the PPC is, and describe the PPC's purpose and its function.
