• • Presentation of the main parameters of the power unit in normal and emergency modes;
• • Critical Safety Functions (CFS) Status View;
• • Presentation of the status of the main equipment of the power unit safety systems;
• • Archiving.

SPPB includes 1011 discrete, analog and calculated parameters, and the configuration of the system enables parallel operation of plant workers and emergency services.
