LIC Distribution cont. Enclosure Thermal LIC: (may be subsumed into Facility or Enclosure LIC) Enclosure LIC: Enclosure Drive Controllers Global Interlock Controller (GIC) Facility LIC: Ground level of operations building September 24, 2009 ATST GIS SDR 6

Network Topology • LICs and GIC – – Safety network Ethernet safety protocol Isolated network Fiber pair, multimode • Safety I/O modules – Subsystem safety network – Ethernet safety protocol – CAT 7, twisted pairs • All the safety I/O are defined in ICD • Provision must be made to add safety I/O • CIP Safety protocol built into safety PACs September 24, 2009 ATST GIS SDR 7

Connectivity to GIS • Interconnects: Ethernet • Protocol: CIP Safety • Tags: major_minor_component_signal e. g. LIC 3_TEOA_heatstop_cover September 24, 2009 ATST GIS SDR 8

Emergency Stop System September 24, 2009 ATST GIS SDR • Current generation e-stop buttons • Hardware independent shutdown of motion controlled devices • GIS monitoring of e-stop – Additional global interlock response – Location • Location and mounting of e-stops as per NFPA 79, Electrical Standard for Industrial Machinery, 10. 7 Devices for Stop and Emergency Stop 9

Compatibility Maintaining compatibility throughout GIS requires specification of both hardware and programming used in subsystems. ATST SPEC-0046 • Specification of the hardware used for the GIC and LIC (1756 Guard. Logix Safety PAC) • • Specification of hardware used by subsystem vendors for safety I/O connection to LIC (1791 ES Guard I/O modules) Specification of the software used in the GIC and LIC (RSLogix 5000) Specification of the software TAGS and use of certified function blocks (TÜV Certified) Communicate on independent safety network (Ethernet/CIP Safety) September 24, 2009 ATST GIS SDR 14
