World's First Truly Integrated Safety Controller

Yokogawa puts an end to DCS-SIS incompatibility with the ProSafe-RS, the world’s first truly integrated "safety PLC" for the process industries. Achieving absolute integrity between distributed control system (DCS) and safety instrumented system (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.

ProSafe-RS R4 adopts the same architecture as CENTUM VP R6 to provide an optimum environment (remove uncertainty and waste) from plant design, realization, installation, operation and maintenance through the introduction of F-IO/N-IO, FieldMate Validator and Automation Design Suite (AD Suite).

 

Sales Release of ProSafe-RS R4.03.10

With the release of ProSafe-RS R4.03.10, it enables a SIL2 wireless gas detection system for FGS. In conjunction with  expertise in production control, safety instrumentation, field wireless engineering and consulting, Yokogawa offers the most efficient and timely approach to deliver  end to end wireless  solution.

ProSafe-RS (SIL3 SIS) and
YFGW510 (Field Wireless Access Point)

 

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  influenced by factors such as installation location and ambient conditions.  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.
(Will be released in September.)

10 years and thanks for the future

ProSafe-RS was released in February 2nd 2005. It can be fully integrated with CENTUM series integrated production control systems, and is certified for use in SIL3 applications. Since its release, ProSafe-RS has been implemented in more than 2,100 projects around the world.

In February 2015, Yokogawa was awarded the Japan Techno-Economics Society's President's Award.

ProSafe-RS is composed of the Safety Engineering PC (SENG) equipped with engineering and maintenance functions, the Safety Control Station (SCS) for safety control and Vnet/IP for control network to communicate with each of those equipment.

ProSafe-RS can be integrated with the CENTUM VP. The SCS can be operated and monitored by the HIS (Human Interface Station) of the CENTUM VP. It is also possible to connect to other DCSs and PLCs via subsystem communication (Modbus communication).

HART communication on ProSafe-RS allows Plant Resource Manager (PRM) to manage the HART communication devices connected to I/O modules on SCS. Also, the AO signal allows PRM client to conduct Partial Stroke Test (PST) on HART-supported valve positioner equipped with the PST function.

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.

Yokogawa's parallel engineering

Application engineering and hardware engineering can progress independently and parallel. This parallel work shortens the project schedule, either by starting later or by possibly enabling an earlier start-up.

Eng-startup

1. Early start-up of a plant

Starting up a plant more quickly has long been an issue that directly affects customers’ profits.

Although the start-up of instruments and the installation of I/O modules can be performed in parallel, the loop check is completed only after the FAT (Factory Acceptance Test) is finished and the controller and the engineering environment are installed.

In Yokogawa’s parallel engineering, there is no need to wait for the controller and engineering environment to be completed. The integrity of loops can be checked only with N-IO modules and FieldMate Validator. If any change is found in the I/O definition information, it can be corrected on the spot, and the corrected definition can then be refiected in the master information in the plant.

FieldMate Validator

2. Reducing risks to scheduled project delivery

The I/O definition often needs to be changed due to physical constraints. Such problems usually occur during commissioning and may prolong the project schedule, as well as require costly re-wiring.

The I/O definition of N-IO modules can be changed more fiexibly. Signal types among DI/DO/AI/AO can be switched only with software, and there is no need to change I/O modules. Since signal types can be designated at each channel, there is no need to stock I/O modules for each signal type, reducing maintenance costs.

Automation Design Suite (AD Suite)

ProSafe-RS R4 features AD Suite, the same engineering environment used with the CENTUM VP integrated control system, allowing the integrated management of CENTUM VP and ProSafe-RS data.
With this feature, ProSafe-RS engineers can use AD Suite to design the I/O.
AD Suite also has functions for managing the change history and recording changes that save time when renovating systems.

ADSuite

Safety Lifecycle Management Support Function

This function is realized by combining Automation Design Suite (AD Suite) of the ProSafe-RS and iDefine for ProSafe-RS (developed by Trinity Integrated Systems). It provides support to the management of functional safety, advanced application logic generation and advanced test functions.

Advanced Application Logic Engineering

  • For ESD and FGS application, the relationship of input and output variables can be defined in the Cause & Effect (C&E) Module which can be automatically generates into format of IEC 61131 Function Block Diagram(FBD).
  • For BMS application, the State Analysis (SA) module can be used to develop state chart style models to describe the detailed behavior of the application. FBD can also be generated automatically based on the State Analysis Chart.
  • The verification of partial or overall operations of the application can be performed by the Cause & Effect function or the State Analysis function, the specification can be validated step by step.

Advanced Test Function

  • The test function allows the user to test the application logic and automatically generate the test report by using test scripts. The test scripts can be used repeatedly until the application logic becomes error-free.
  • The test results can be confirmed visually and in real time with the C&E and SA chart. Full history recording, event recording and playback enables further review and refinement.

FSM support function

It uses a whiteboard template to provide support for

  • Defining safety and project lifecycle phases
  • Resources assignment
  • Planning activities
  • Identifying functional assessment and verification milestones

 

The logical solution for perfect control

The logical solution to perfect control

One network

ProSafe-RS plugs directly onto the same network used by Yokogawa's field-proven CENTUM VP.  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

  • 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.

It's now easy to create displays that integrate DCS and SIS data.

In addition to conventional I/O modules dedicated for specific signal types (FIO module), ProSafe-RS R4 can offer the N-IO module, which handles different signal types at each channel.
By concurrently accepting both types of module, ProSafe-RS R4 can deal more flexibly with a customer’s plant design requirements. 

N-IO

N-IO (Network I/O): Smart Configurable I/O (SCIO)

Features

  • DI/DO/AI/AO signals can be handled at a single module.

N-IO

A single, simple, SIL3 solution

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

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.

Versatile Modular Redundancy (VMR)

Versatile Modular Redundancy

With its flexible selection of redundant CPU and I/O modules, ProSafe-RS delivers the high availability required by even SIL3 applications. Rather than making selections at the system or rack level, you can apply redundancy exactly where it is needed - in specific input, output or processor modules - depending on such factors as the required SIL for a loop or the reliability of field devices.This is possible because the I/O and processing functions of ProSafe-RS have a modularity that extends down to the function level.

Even when an internal failure occurs, safety functionality is maintained, reducing the likelihood of a false trip in a process.
We call this flexible plug-in availability “VMR / Versatile Modular Redundancy™".

Partial Stroke Test (PST)

Under normal conditions, valves that are integrated with a safety instrumented system (SIS) are not activated. (They are only actuated when the SIS initiates a process shutdown after an abnormality is detected in a process.) It is therefore necessary to periodically test valves to ensure that they are in good working order and will respond properly when needed.

This periodic check is called a “proof test,” and generally it involves a full stroke test (completely closing the valves). When a plant is up and running, the costly installation of a bypass is necessary to conduct a proof test. If this is not possible, the only other option for conducting this test is to shut down the plant. As a consequence, proof tests of the valves are usually conducted only once every several years.
 
An alternative to the full stroke test is the partial stroke test (PST), which involves slightly closing a valve to diagnose problems. A PST can be conducted without stopping a process, and it can be performed remotely from locations such as a control room.

By conducting a PST, plant owners can significantly reduce their maintenance costs. And by checking the valves more frequently than is possible with the full stroke test, they can anticipate great benefits such as increased reliability .

Note: although the PST does not eliminate the need for a full stroke test, it makes it possible to extend the proof test interval without sacrificing the required safety level.

Migration from Legacy System to ProSafe-RS

Difficulty in continuing to maintain your legacy system due to higher costs of maintenance, deteriorating performance, unavailable of spares parts (SIS and PC), uncertain documentation and compliance issues. Yokogawa provides latest SIS and engineering services to migrate/replace your existing system.

Depending on your site situation and migration window, Yokogawa ProSafe-RS offers two options of IO system namely F-IO (conventional IO) and N-IO (smart configurable IO) to allow smooth and low risk migration..

Yokogawa offers services to reverse documentation and application of your legacy system. Validation can be done offline in advance with subject matter experts (Operator, Process Engineer, Maintenance Engineer) and leads to high level of confidence of the conversion. Finally, the validated documents can be imported to ProSafe-RS for application generation.

 

Migration from ProSafe-PLC to ProSafe-RS

Yokogawa is now offering a service that will allow you to migrate from the well proven ProSafe-PLC platform to our latest safety instrumented system, ProSafe-RS. ProSafe-RS uses a faster CPU and is seamlessly integrated with the CENTUM DCS, greatly improving performance and eliminating the need for a dedicated DCS gateway. ProSafe-RS provides complete integration with the operation and monitoring functions of the CENTUM DCS.

 

Two migrations plans are available to suit your project needs:

Plan 1 (recommended)
This is a complete replacement of the entire ProSafe-PLC system, including control and I/O modules, terminal boards, and wiring, with all elements of the ProSafe-RS system. The compact terminal boards are a key element of this plan.

Plan 2
The ProSafe-PLC control and I/O modules are replaced with ProSafe-RS control and I/O modules. With this plan, the existing field wiring can be used because the modified system continues to use the ProSafe-PLC terminal boards. This plan is implemented with the migration adaptors and the related products.
(Note: The end of support date for the ProSafe-PLC terminal boards is 2018.)

Yokogawa Technical Report
Overview:

The recent variety of industrial and railway accidents happening right before our very eyes make us painfully aware that "safety" must be put first and foremost. "Safety first" is a concept accepted by everyone and there is no room for disagreement. However, the author feels that, in some cases, the concrete objectives of "safety first" are not actually clear, and the grasp of the hazards is insufficient.

Industries:
Overview:

In recent years it has become increasingly common for plants to be provided not only with the control layer of a production control system (DCS, etc.), but also with the protection layer of a safety instrumented system (SIS) to reduce the risk of industrial accidents. The safety instrumented system is indispensable for avoiding risks to a plant failure.

Industries:
Yokogawa Technical Report
Overview:

Yokogawa proposed the VigilantPlant concept as an ideal plant that achieves fully optimized operation where all the necessary information is given to all the operators involved in the plant operation. In VigilantPlant, operators are able to quickly respond to changes in the external environment while the production activities run without any interruption.

Overview:

In Japanese industries which grew rapidly until the early 1990's, solid production techniques for creating high-quality products supported the development of manufacturing industries. However, the economic environment has been changing rapidly and tough global competition has become unavoidable. Particularly, the manufacturing industry must adapt not only to changes in economic environments but also to changes in social conditions such as emphasis on health, safety, and environment (so called HSE).

Overview:

Upgrading and renewal of plant facilities, including production control systems and safety instrumented systems, are essential for maintaining safe and efficient plant operation. Even though these activities are categorized as R&R, they require investment and customers are often required to evaluate the profitability for obtaining approval.

Yokogawa Technical Report
Overview:

Environment and safety are major topics on a global scale in recent times. As symbolized by the effectuation of the Kyoto Protocol, an interest in preserving the environment is growing worldwide, and there is also a tendency to criticize more severely, occurrences of industrial accidents that are accompanied by environmental contamination or which may cause damage, etc., to residents in the surrounding areas.

Overview:

Conventional safety instrumented system (SIS) is typically installed separated from a distributed control system (DCS) to eliminate interference from the DCS and assure safety. However, users increasingly wish to integrate SIS with DCS while maintaining the safety of safety controllers.

Industries:
Overview:

Yokogawa's ProSafe-RS safety instrumented system is used for many applications as a system conforming to the safety integrity level (SIL) 3 defined in the IEC61508 international functional safety standard. To deal with temperature inputs, systems were conventionally configured using signal conditioners.
