World's First Truly Integrated Safety Controller: Safe, Reliable and Available Control Without Compromise

Overview
World's First Truly Integrated Safety Controller

Achieving absolute integrity between distributed control systems (DCS) and safety
instrumented systems (SIS) for plant automation has traditionally raised complex design
and integration issues.
Conventionally, two separate monitoring and operating environments were required for a
DCS and SIS. Different communications and distinctive hardware architectures had to
be set up. Plant managers striving to optimize process operations have taken it as a
given that project time and expenses would escalate.
Now Yokogawa puts an end to DCS-SIS incompatibility with the new ProSafe-RS, the
world’s first truly integrated "safety PLC" for the process industries.
Integrated System
Safe, reliable and available control without compromise

One architecture
Seamless architecture achieves true integration of DCS and SIS, contributing to

plant optimization.
Expected operational benefits:

- faster project implementation at a lower cost - using just one process network saves
engineering design time
- greater operational efficiency - integrated information displays are clearer and more
usable
- lower cost of ownership - common control and network architecture standards
cut maintenance overhead
Eliminating SIS selection complexities

ProSafe-RS is SIL3 certified in a single module configuration. Redundancy is already
built-in to each ultra-compact input, output, and processor card. This intrinsically simple
modularity makes it possible to design systems with ease. If additional system availability
is required, users can add redundancy on a function by function basis by simply plugging
in the appropriate module.
Safety Communication
The logical solution for perfect control

——————————————————————————————————————
One network
ProSafe-RS plugs directly onto the same network used by Yokogawa's field-proven
CENTUM CS 3000 R3. No gateway or interface hardware is required for data exchange
between SIS and DCS functions. Safety communication between SIS controllers is
realized and certified in a mixed DCS - SIS configuration.
Expected benefits:
- simple and quick route to system realization
- reduced engineering complexity and cost for connecting SIS and DCS
- lower maintenance costs for large process plants
Human Machine Interface

Significant gains in the capabilities of plant displays
——————————————————————————————————————
One window
Advanced Technologies:
- Common human-machine interface (HMI)
No more separate monitoring of SIS and DCS.
While continuing to use the interface that they are
most familiar with, operators can more rapidly
predict which process conditions are likely to
reach emergency levels.
- Unified event data
Sample screens such as "faceplate" style instrument and alarm displays are provided
that enable easy data comparison and decision making.
- Back-tracking analysis
A further benefit of data integration is the ability to analyze events preceding an alarm
- a powerful tool for effective process safety management.
It's now easy to create displays that integrate DCS and SIS data.
Safety and Availability
A single, simple, SIL3 solution

——————————————————————————————————————
Yokogawa designers have employed state-of-the-art electronic design techniques and

component packaging to miniaturize the safety controller circuitry. Every ProSafe-RS
processor, input module, and output module features a dual architecture, providing users
with SIL3-level protection on a single card. This architecture is simplicity itself to
understand, design, install and maintain. Complete safeguarding now comes in one box.
Furthermore, the design has an extremely high diagnostic coverage factor of more than
99%, providing users with a means of rapid fault detection that can allow repairs to be
effected within an acceptable period - with minimal impact on the process.
Plug-in availability
——————————————————————————————————————
If even higher system availability and fault tolerance is required, ProSafe-RS can be
configured for dual redundancy while maintaining SIL3 by simply plugging in the
appropriate additional card. Because the I/O or processing functions of ProSafe-RS have
a modularity that extends down to the function level, redundancy can be applied exactly
where it is needed - to input, output, or processor modules - providing a combination of
safety and economy that is unprecedented in the SIS market. This flexibility allows any
mix of dual redundancy to be configured such as a single input and redundant output or
a redundant input and single output.
Small and Scalable
A breakthrough in size reduction
——————————————————————————————————————
The miniaturization of ProSafe-RS cards not only has system configuration benefits, but
also provides a breakthrough in SIS footprint and cabinet size. The ProSafe-RS
architecture offers SIS users significant space savings compared with other safety PLCs
on the market today. It is particularly beneficial in any application where space or weight
is at a premium -such as offshore platform equipment rooms or the remote equipment
stations at larger-scale process plants.
Highly scalable architecture

——————————————————————————————————————
ProSafe-RS employs the same flexible architecture of CENTUM CS 3000 R3, allowing
SIS functions to be configured for applications of any size. ProSafe-RS can also meet
the requirements of a variety of configurations including centralized and distributed
systems.
