Tokyo, Japan - July 25, 2017
Yokogawa Electric Corporation (TOKYO: 6841) announces that it will release the ProSafe-RS® SIL2*1 wireless gas detection system in September.
The ProSafe-RS SIL2 wireless gas detection system will consist of a newly enhanced version of the Yokogawa ProSafe-RS SIL3 safety instrumented system (R4.03.10), Yokogawa field wireless network devices, annunciator panels, and GasSecure*2 GS01 or GS01-EA*3 wireless gas detectors.
For this system, Yokogawa will establish a total solution that will include both consulting and engineering.

In energy and basic materials industries such as oil, gas, petrochemicals, and chemicals, a safety instrumented system is employed to safely initiate an emergency plant shutdown when a critical failure is detected, and to initiate the operation of facilities that can extinguish or prevent the spread of a fire.
A field wireless system consists of field devices that are able to communicate wirelessly with a monitoring and control system. Wireless devices have a number of advantages such as allowing installation in difficult-to-access locations and the reduction of installation costs, and they are increasingly seen as essential elements in plant safety solutions. This is a particularly important consideration with gas detection systems, whose operation can be easily impacted by factors such as installation location and ambient conditions. And even after system installation, ongoing efforts to optimize its overall configuration may necessitate occasional changes in the location and number of detection devices. The use of wireless technology eliminates the need to worry about wiring and thus greatly facilitates the process of moving and/or installing additional detection devices.
To achieve SIL2 level risk reduction when using wireless gas detectors with a safety instrumented system, communication protocols that comply with the functional safety requirements specified in the IEC 61508 international standard*4 are required. To meet this need, Yokogawa will provide a SIL2 wireless gas detection system based on a new version of the ProSafe-RS safety instrumented system that will link to field devices using an IEC 61508 compliant communication protocol.
The ProSafe-RS SIL2 wireless gas detection system will consist of a new version of the ProSafe-RS safety instrumented system, R4.03.10, that will be enhanced to add support for an IEC 61508 compliant safety communication technology used in distributed automation; annunciator panels; ISA100 Wireless*5 compliant field wireless devices; and GasSecure GS01 or GS01-EA wireless gas detectors, which are the only devices of this type in the industry that achieve SIL2 risk reduction.
Released in February 2005, the ProSafe-RS safety instrumented system helps prevent accidents by detecting abnormal conditions in plant operations and initiating emergency actions such as a plant shutdown. An independent certification body has certified that ProSafe-RS can be used in SIL3 applications. Unlike conventional safety instrumented systems and distributed control systems, which are regarded as having different roles and functions and operate separately, the operation of ProSafe-RS and the CENTUM integrated control system can be fully integrated. ProSafe-RS is highly regarded by users and has been installed in more than 2,100 projects worldwide (as of June 2017).
Yokogawa developed wireless communication technologies for continuous processes that necessitate advanced control and released the world's first ISA100 Wireless system devices in July 2010, thereby offering its customers a wider range of products to choose from. Currently, Yokogawa offers its customers in the oil, gas, and other industries a wide range of field wireless management stations, field wireless access points, wireless field devices, and wireless adapters for conventional wired devices.
For use in fire and gas systems (FGS) and emergency shutdown systems (ESD) in process industries such as oil, natural gas, petrochemicals, chemicals, pharmaceuticals, electric power, and iron and steel
*1 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. At SIL2, the risk factor for a plant where safety measures are not in place is in a range between 1/100 and 1/1,000. At SIL3, the risk factor is in a range between 1/1,000 and 1/10,000.

*3 Equipped with an extension antenna
*4 A standard for the functional safety of electrical/electronic/programmable safety-related systems
*5 A network protocol based on the ISA100.11a wireless communication standard for industrial automation that was developed by the International Society of Automation (ISA), and the applications necessary for its implementation. This was approved as the IEC 62734 international standard in October 2014.
