The CERN Unified Industrial Control System framework (UNICOS) with its Continuous Control Package (UNICOS CPC) is the CERN standard solution for the design and implementation of continuous industrial process control applications. The in-house designed communication mechanism, based on the Time Stamp Push Protocol (TSPP) provides event driven high performance data communication between the control and supervision layers of a UNICOS CPC application. In its recent implementation of full redundant capabilities for both control and supervision layers, the TSPP protocol has reached maturity. This paper presents the design of the redundancy, the architecture, the current implementation as well as a comprehensive evaluation of its performance for SIEMENS PLCs in different test scenarios.

During the first 3 years of LHC operation, the priorities for the vacuum controls SCADA were to attend to user requests, and to improve its ergonomics and efficiency. We now have reached: information access simplified and more uniform; automatic scripts instead of fastidious manual actions; functionalities and menus standardized across all accelerators; enhanced tools for data analysis and maintenance interventions. Several decades of cumulative developments, based on heterogeneous technologies and architectures, have been asking for a homogenization effort. The Long Shutdown (LS1) provides the opportunity to further standardize our vacuum controls systems, around Siemens-S7 PLCs and PVSS SCADA. Meanwhile, we have been promoting exchanges with other Groups at CERN and outside Institutes: to follow the global update policy for software libraries; to discuss philosophies and development details; and to accomplish common products. Furthermore, while preserving the current functionalities, we are working on a convergence towards the CERN UNICOS framework.

The control systems of most of the infrastructure at CERN makes use of the SCADA package WinCC OA by ETM, including successful projects to control large scale systems (i.e. the LHC accelerator and associated experiments). Each of these systems features up to 150 supervisory computers and several millions of parameters. To handle such large systems, the control topologies are designed in a hierarchical way (i.e. sensor, module, detector, experiment) with the main goal of supervising a complete installation with a single person from a central user interface. One of the key features to achieve this is alarm management (generation, handling, storage, reporting). Although most critical systems include automatic reactions to faults, alarms are fundamental for intervention and diagnostics. Since one installation can have up to 250k alarms defined, a major failure may create an avalanche of alarms that is difficult for an operator to interpret. Missing important alarms may lead to downtime or to danger for the equipment. The paper presents the developments made in recent years on WinCC OA to work with large hierarchies of alarms and to present summarized information to the operators.
