UNICOS CPC provides libraries (control and
supervision layers)
A well defined set of standard device types (objects),
modeling most of the equipment and needs of
continuous processes and the relationships between
them
A formalized way of :
• Define the control units of a process (ISA-88
standard: Batch processes)
• Programming the specific process logic for those
units

• Time Stamp at source per UNICOS CPC object (same for
each table)
• Data filtered and encapsulated in the PLC.
• Large buffer of events to prevent data loss.
• Reliability
• High performance
