  • Provide operator interface for monitoring and control via operator console (Human Machine Interface)

  • Provide alarm/event logging and trending facilities

  • Generate production data reports

Basic Process Control System (BPCS) is also considered as one of safety layer preceding Safety Instrumented System (SIS) within a facilities.
