exida’s Hal Thomas receives ISA Standards and Practices Department Award

Exida HalAward-cropped.jpgHal Thomas, exida Partner has been awarded the ISA Standards and Practices Award for his outstanding leadership and technical expertise as ISA84 Working Group 9 chairman in the development of ISA-TR84.00.09-2013, Security Countermeasures Related to SIS.

Mr. Thomas has over 36 years of professional experience. He is widely recognized as an expert in functional process safety analysis, including safety instrumented systems and high availability automation systems. He helped pioneer the use of HAZOP, fault tree analysis, consequence analysis, LOPA, and introduction of the SIS work process while at Air Products. He was formerly an Engineering Associate – Process Safety and Technology Manager for Safety Instrumented Systems at Air Products and Chemicals, Inc. His principle work responsibilities included assisting and mentoring process safety and process control engineers in hazard identification, the use of fault tree analysis, LOPA, SIL assessment, SIL verification, leading new technology hazard reviews, as well as to write standards and procedures to promote high quality and consistent results.

He helped institute a managed system of standardized consequence analysis procedures and managed the development of a number of in house tools and models to support both likelihood and consequence analysis. He has served on a number of CCPS committees that have written guideline books, and is an original member of the CCPS Process Equipment Reliability Database initiative. He is a member of the CFSE Governing Board and is a senior member of ISA. He has authored numerous published papers.


RPC Radiy’s FPGA-Based Safety Controller certified for SIL 3 by Exida

Exida, one of the leading certification bodies for functional safety and security standards, assessed RPC Radiy’s RadICS FPGA-Based Safety Controller (FSC) per the relevant requirements of IEC 61508:2010, parts 1-7 and found that it meets requirements providing Safety Integrity Level (SIL) 3.

Radiy’s RadICS FSC will read input signals, perform user-defined application layer logic and write results to the output signals within the stated response time. The FSC can be used for design and development of SIL 3 level applications.

“Radiy has developed unique technology that utilizes FPGAs to implement logic solver capabilities,” said Dave Butler, exida evaluating assessor. “Their strong development process ensures the delivery of products that achieve high levels of functional safety.”

The following is from the exida assessment report:

“The audited development process as tailored and implemented for the RPC Radiy FPGA-based Safety Controller (FSC) RadICS development project, complies with the relevant safety management requirements of IEC 61508 SIL 3.

“The assessment of the FMEDA, done to the requirements of IEC 61508, has shown that the FPGA-based Safety Controller (FSC) RadICS can be used in a Low Demand safety related system in a manner where the calculated PFD AVG is within the allowed range for SIL 3 (HFT >= 0) according to table 2 of IEC 61508-1.

The RadICS platform (see Fig. 1) is a set of general-purpose building blocks that can be configured and used to implement application-specific functions and systems. The RadICS platform is composed of various standardized modules, each based on the use of FPGA chips as computational engines.

The basic configuration for the RadICS platform consists of an instrument rack containing two logic modules, as well as up to 14 other I/O modules and fibre-optic communication modules. Logic modules gather input data from input modules, execute user-specified logic, and update the value driving the output modules, as well as gather diagnostic and general health information from all I/O modules. The I/O modules provide interfaces with field devices (for example, sensors, transmitters, actuators). The functionality of each module is driven by the logic implemented in the on-board FPGA(s).

The basic set of I/O modules consists of analogue and digital input, and digital output modules. There are also special-purpose I/O boards designed for specific field detectors and devices, such as resistance temperature detectors (RTDs), thermocouples, ultra-low voltage AI boards used for neutronic instrumentation, actuator controller modules, and fibre-optic communication modules that can be used to expand the I&C system to multiple chassis. It is also possible to provide inter-channel communications between 2, 3 or 4 channels via fibre-optic communications directly between logic modules.

The backplane of the RadICS platform provides external interfaces to power supply, process I/Os, communication links, and local inputs and indicators. The internal backplane interfaces provide connections to the various modules that are installed within the chassis by means of a dedicated, isolated, point-to-point low-voltage differential signalling (LVDS) interface.

Yokogawa's ProSafe-RS Safety Instrumented System wins CIS Science and Technology Award

Yokogawa Electric Corporation announces that one of its major platform products for the industrial automation and control business, the ProSafe®-RS safety instrumented system (SIS), has received a Science and Technology Award in the Excellent Product category from the China Instrument and Control Society (CIS).

The award was presented on September 23 in a ceremony that was conducted at the opening of the 25th International Conference and Fair for Measurement Instrumentation and Automation (Miconex 2014), a CIS-sponsored event in Beijing, China. Yokogawa China Co., Ltd., a Yokogawa subsidiary, accepted the award certificate on Yokogawa’s behalf.

The CIS Science and Technology Award was established by the National Office for the Science & Technology Awards and the Ministry of Science and Technology of the People’s Republic of China, and is considered to be highly prestigious and influential. This year, 21 products won this award in the Excellent Product category, and it is particularly noteworthy that Yokogawa was the only non-Chinese company to receive this honor. This award for ProSafe-RS is the first time an SIS has won this honor, and it comes in recognition of our success in supplying many ProSafe-RS SISs in China which can be attributed to the high reliability of the ProSafe-RS and the enhancement to plant operations that comes through integration of ProSafe-RS and the Yokogawa CENTUM® VP integrated production control system. CENTUM VP received this award last year, making this the second consecutive year that we have received this award.

In energy and raw materials industries such as oil, natural gas, petrochemicals, and chemicals, there is a strong demand for solutions that will help to ensure a safer workplace. Safety instrumented system can detect hazardous conditions and initiate an emergency shutdown. To improve plant safety, the Chinese government is recommending the use of safety instrumented systems. Yokogawa will continue to provide products and other solutions that can enhance both operational efficiency and safety in China.

EXIDA releases SILStat v2 Ooperation and Maintenance Data Collection Software

Exida, a global supplier of functional safety products, services, and certifications has released the second version of its SILStatTM software. SILStat helps evaluate actual risk reduction by collecting and analyzing operation and maintenance data.

“SILStat v2 improves the scalability of the software rollout through a standalone (Lite) and Server based (Site) offering,” says Iwan van Beurden, exida’s director of product development. “Data collected by SILStat can help determine the actual risk posed by a hazardous situation and the effectiveness of the individual layers of protection allowing safety practitioners to evaluate the effectiveness of their process safety design and consider actual performance in future hazard and risk evaluations.”
