Best Safety Instrumented Systems for Linux

Combining the form factor and ruggedness of a PLC with the power and ease-of-integration of the Ovation control system, the compact controller is a reliable automation platform scalable for any power generation or water/wastewater application that needs control to be located near the equipment. Efficient and safe remote asset management from anywhere increases reliability and reduces costs. In addition to native, advanced applications for optimizing plant operations, Ovation supports integrated vibration monitoring, generator excitation control, SIS, scalable footprints for small or distributed applications, virtualization and embedded simulation.

ProSafe-RS Lite conforms to the international safety standard for up to SIL2 application. You can select the ProSafe series from SIL2 (ProSafe-RS Lite), SIL3 (ProSafe-RS), and SIL4 (ProSafe-SLS). Continued functional enhancements to ProSafe series help you run your plants safely. Established by the International Electrotechnical Commission (IEC), a safety integrity level (SIL) indicates the relative level of risk provided by a safety function. SILs 1 through 4 are defined by IEC 61508. Compared to a plant where safety measures are not in place, at SIL2 the risk factor is reduced to between 1/100 and 1/1,000. At SIL3, the risk factor is in a range between 1/1,000 and 1/10,000. At SIL4, the risk factor is in a range between 1/10,000 and 1/100,000. ProSafe-RS Lite inherits the highly reliable technology of ProSafe-RS, and by combining it with CENTUM VP/ProSafe-RS, enables integrated operation that includes process and safety control.

The ProSafe-RS safety instrumented system is a TÜV certified Safety Instrumented System (SIS) for use in SIL 1, 2, and 3 applications in a single modular configuration, with superior availability in a redundant configuration. It can be a standalone system or tightly integrated with our CENTUM VP Distributed Control System. Yokogawa industrial safety systems minimize interruptions with highly reliable protection at all SIL levels, real-time dashboards, quantifying current and future risks, and virtual scenario testing to assess the impact of future bypasses and overrides. Online modification, which allows plants to continue to run during upgrades, automated compliance reporting to optimize testing frequency, and cradle-to-grave service and lifecycle assurance. As the last line of defense, the safety controller must act reliably exactly when it needs to. Yokogawa's exclusive Versatile Modular Redundancy maintains unlimited SIL 3 operation even under multiple failure scenarios.

ProSafe-SLS is Yokogawa's solid-state, hard-wired safety instrumented system designed to meet the highest safety integrity requirements. The product line meets specific requirements for individual safety instrumented systems and offers all safety integrity levels (SIL 3-4) for the oil and gas, petrochemical, chemical, nuclear and conventional power industries. ProSafe-SLS safety instrumented system is also fully integrated with Yokogawa's CENTUM VP process control system as well as the FAST/TOOLS SCADA software package. The modular design of the ProSafe-SLS safety system allows for building all kinds of applications, ranging from small HIPS systems to large ESD and F&G systems while maintaining the fastest possible response time to follow any process demand. The ProSafe-SLS is a safety instrumented system that was designed for applications that require the highest Safety Integrity Levels (SIL 3 & 4). It employs solid-state elements to process the functional logic.

In spite of decreases in CAPEX and OPEX, operators today must minimize unplanned downtime while maintaining functional safety compliance according to ISA84/IEC 61511. Is your operation able to accurately track data for safety system performance monitoring and compliance? Throughout the plant lifecycle, Yokogawa’s Sustainable Functional Safety Management (FSM) solution continually analyzes all demands for safety action and failures in process operations vs. Safety Performance Indicators. This process provides continual safety performance updates to all plant personnel. Active management of operational safety information enables continuous compliance with IEC 61511 and ISA84 over the entire asset lifecycle. Once the operation has completed the safety instrumented system (SIS) design and layer of protection analysis (LOPA), the configuration of process safety monitoring is automated. Our sustainable FSM solution also automates change management.
