Industrial Controls Engineering Department • • • UNICOS CPC overview TSPP manager Performance Highlights Outline J. Ortola (CERN, EN/ICE) December, 2014 2
Industrial Controls Engineering Department • • • 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 UNICOS CPC J. Ortola (CERN, EN/ICE) December, 2014 3
Industrial Controls Engineering Department • 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 S 7 300, S 7 400 (S 7 1200, S 7 1500 in preparation) • Schneider • Beckhoff (Codesys) TSPP overview J. Ortola (CERN, EN/ICE) December, 2014 4
Industrial Controls Engineering Department • TSPP requisites • • S 7 driver for S 7 PLCs Modbus driver for Schneider and Beckhoff TSPP layer at the SCADA level (currently only Win. CCOA) OPC UA client (coming soon) with Simatic. NET TSPP overview J. Ortola (CERN, EN/ICE) December, 2014 5
