3. 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
