Is your guardian vigilant? Offshore The Best and Most Dependable Partner for Safety Excellence With its industrial automation solutions, Yokogawa is committed to being a vigilant partner for its customers and to helping them achieve Operational Excellence, Asset ergency Shu (Em MS ( Burne tdown Sy ste rM SD ● B ●E ● F& anagem m) e G (Fir e and nt System) Gas Syst e m) Excellence, and Safety Excellence. One such core solution is the ProSafe-RS safety instrumented system (SIS), which plays a crucial role in ensuring plant safety and draws from our supremely reliable distributed control system (DCS)...

The Best Safety Architecture : SIL3 and high availability through VMR technology What is VMR ? When an even higher level of system availability and fault tolerance is required, ProSafe-RS can be made dual redundant by simply plugging in an additional card. This flexible plug-in capabilit y is called “VMR/Versatile Modular Redundancy TM”. Because the I/O and processing functions of ProSafe-RS are modularized right down to the function level, redundancy can be applied exactly where it is needed – to the input, output, and processor modules – providing the perfect combination of safety and economy....

The Best Performance : First-rate processing With a redundant CPU configuration, two CPU modules perform exactly the same actions. Should the control CPU fail, the stand-by module can assume control within 100 µs, with no impact on the process. The same applies to redundant I/O modules: switching occurs within tens of milliseconds and the process continues uninterrupted. Control Bus (Vnet/IP) Application Program Memory (Flash Memory) The Best Performance Based on Yokogawa’s long experience in industrial automation, ProSafe-RS has been designed with a very high level of reliability and safety....

The Best Performance : The wise choice CPU node for applications spread over a wide area Module Selection I/O modules accommodate various signal ranges and levels including 4-20 mA, 1-5/1-10 V, TC, RTD, 24/48 V DC, and 120 V AC. For analog inputs, measurement outside the standard ranges is also possible. For example, as current levels in a 0-25 mA range can be measured, errors in a process or in a field device can be detected. And for 24 V DC outputs, various types of modules can be selected according to the output capacity and purpose. In addition to conventional I/O modules for specific signal...

The Best System Integration : One net work control of plant operation How does Yokogawa segregate the SIS from the DCS? The answer is that the ProSafe-RS controllers handle the safety functions and the CENTUM controllers handle the control functions, and this is done independently. Safety communication among the ProSafe-RS components is designed to be logically independent on Vnet/IP, and is thus protected from other communications. Safety communication also suppor ts a broadcast mode for simultaneous communication to all nodes within the same domain, thus ensuring fast safety control even in...
