Personnel safety systems at ESS

• Denis Paulic (CERN)

Room: 774/R-013 A general overview of the whole PSS system at ESS will be presented with emphasis on the PSS architecture, control system components and procedures for the ESS Accelerator. Some of the important safety elements, sensors and actuators for PSS will be presented in more details. To show how these elements can be put together, a test bench is being built at Protection Systems lab at ESS and its status will be presented. A PSS system will be designed and implemented following the IEC 61508 and accordingly, the hazard analysis documents will be presented at the end of the talk.

Safety Instrumented Systems: risk analysis and implementation in the SM18 test bench

Combining safety and conventional interfaces for interlock PLCs (Ignacio Prieto Diaz & Riccardo Pedica) Room: 774/R-013 The ITER procurement strategy mixes systems delivered in-fund and in-kind, this complicates considerably the integration of the whole interlock system. In oder to cope with this, the interlocks design and integration strategy is based on guidelines and template codes developed by the central team for  easing the work of the plant sytem developers and mitigating future integration risks. This talk presents the tools developed by the ITER central team for ensuring the integrability of a robust ITER machine protection sytem which still leaves some room to cope with the operational flexibility required by such a complex system as the ITER tokamak.

Siemens TIA portal Openness feature for automatic code generation at ESS (Nikolay Levchenko) Room: 774/R-013 Siemens is gradually moving towards replacing the legacy SIMATIC software suite with the new TIA Portal software package. This is a fully reworked software and it is intended to provide a lot more flexibility, reliability and user-friendliness for all the Siemens PLC users in future. TIA Portal comes with so called Openness feature which provides engineers with the means to externally interact with TIA Portal. In this presentation we will look into the details of this feature and how it can be used in future development of PLC code (automatic code generation, compiling, uploading/downloading, etc.).

ESS controls infrastructure (Daniel Piso) Room: 774/R-013 The purpose of this presentation is to give a description of the status of the ESS control system, trying to focus on the aspects like hardware strategy, standardisation and PLCs. Besides, we will do and overview of the timing system, his main characteristics and capabilities.

PLC vacuum controls architecture at ESS

• Francois Paul Bellorini (CERN)

Room: 774/R-013 The purpose of this presentation is to give an overview of the vacuum control at ESS, to describe the vacuum control architecture and to present possible functionality of vacuum interlocks that we plan to implement.

Formal verification of industrial control systems

Development of redundant and reliable Fast Interlock Controllers using COTS based on IEC 61508 (Luis Fernandes) Room: 774/R-013 For interlock functions at ITER requiring a response time faster than the capabilities of the S7-400F PLC an interlock controller using COTS FPGA has been developed. A system based in NI cRIO was designed following the same IEC standard applied to the PLC based interlocks which could reach SIL-3 like integrity.

Fast beam interlock system for machine protection at ESS

• Martinez Angel Monera
• Annika Nordt (European Spallation Source, Lund, Sweden)

Room: 774/R-013 The ESS Fast Beam Interlock System (FBIS) is based on FPGA technology and has very high time and reliability requirements. Its development includes iterative processes to reduce the number of false beam trips and blind failures at the same time as processing time needs to be around 1 µs. This presentation discusses the technologies implemented and possible design choices for the FBIS.

High Performance Computing platform for predictive interlocks using PLCs at ESS

• Manuel Zaera Sanz (Universidad de Valencia (ES))

Room: 774/R-013 Machine protection at ESS is focusing on the protection of investment and beam, aiming for very high beam availability towards the users. To achieve this goal, prediction of interlocks situations may be needed, avoiding beam stops. This predictive approach or just the interlocks situation detection, may imply the need of non-boolean (complex) computations in real-time with even safety critical constraints. We believe that PLCs are suitable candidates to fulfill this task and a PLC based HPC solution proposal will be presented and open for discussion
