UNICOS CPCDecember, 2014

• 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

TSPP overview

• TSPP. Time Stamp Push Protocol• UNICOS CPC middleware• Time stamp at source (from NTP server)• Event driven• High performance• Available for redundant PLC architectures.

• Currently available for• Siemens S7 300, S7 400 (S7 1200, S7 1500 in preparation)• Schneider• Beckhoff (Codesys)

Highlights

• 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
