Remote Delivery (GDC)
Yokogawa의 글로벌 엔지니어링 리소스 센터(Global Delivery Center)는 OpreX를 구현하도록 교육을 받은 조직으로, 프로젝트 엔지니어링을 수행하고, 제3자 시스템 테스트 및 제어·안전 시스템 테스트를 담당합니다.
yi-CLOUD (CEE/CET)

이 기능을 통해 하나의 물리적 서버에서 여러 개의 가상 머신을 실행할 수 있으며, 물리적 PC와 시스템 캐비닛의 수를 줄여 설치 공간, 전력과 발열, 냉각, 유지보수 비용을 절감할 수 있습니다.
Modularization
It consists of N-IO based Standard Enclosure, Smart Junction Box (Smart JB) as hardware platform and Automation Design Suite (AD Suite) as software platform with Industry Libraries.

Fig. Value Drivers enabled by Modularization
Configurable I/O (N-IO with AD Suite)
N-IO with AD Suite enables application development and hardware manufacturing to occur in parallel without dependencies. N-IO supports multiple signal types on a per-channel basis and simplifies field device wiring, eliminates the need for marshalling systems and supports flexible binding. N-IO eliminates the need for specific wiring assignments and full utilization of all points in a module.

Standard Enclosure (with N-IO)

Fig. Standardized ICSS System Architecture
Standard enclosure enables standardization and ensures consistent design and quality. The use of N-IO eliminates cross-wiring and marshalling cabinet engineering. The I/O cabinet is fully standardized with software configurable I/O. Hardware engineering and the design approval processes are minimized with this standard enclosure approach. In this standards approach, enclosures can be ordered by datasheet without the repetitive recycling of drawing approvals. Everyone - Yokogawa, EPC and customer, benefits from reducing engineering man-hours in the design approval process
Smart JB (N-IO)

Fig. Filed Wiring Reduction by Smart JB
N-IO components are designed to be installed in the field. With Smart JB, field devices can be directly connected to the N-IO system. This Smart JB concept provides a significant benefit during construction. Thick and heavy-weight homerun cables are replaced by thin and light fiber optic cables and power cables. Total cable weight, cost, cable trays, related field engineering and documentation (e.g. loop diagrams) can be significantly reduced.
GES Industry Libraries (AD Suite)
Industry Library is one of the key components of Yokogawa’s Global Engineering Standard (GES) Toolkit as a foundation for the module-based engineering approach and it provides a pragmatic way for knowledge management in industrial automation and improves the application of best practices. The main objectives of the GES Toolkit are:
- To make use of proven implementations (learned from others)
- To enable consistent design & implementations
- To improve implementation efficiency
- To reduce known risks
Validation
It includes the various elements to fulfil requirements.
Smart DCS Engineering (Module Eng. with AD Suite)

Fig. Value Drivers enabled by Validation
Module-based engineering utilizing Yokogawa’s AD Suite is the unifying element in the OpreX Project Execution approach. AD Suite is the central engineering application and database for all aspects of an automation project. Yokogawa's engineering platform brings features that enable flexibility to project execution and Key features include:
- Bulk Engineering
- Modular application Engineering
- Automated Document Generation
- Late changes and Flexible Binding
- Re-use application assets (GES Industry Library, Customer standard application etc.)
- Change Management for traceability throughout the project lifecycle.
AD Suite retains the entire engineering history of the plant from design phase through commissioning and live operation, ensuring up-to-date plant knowledge with every expansion or hardware and software change throughout the system lifecycle.

Smart SIS Engineering (Module Eng.)
Similar (almost identical) to the DCS application development, modularized application development is executed for Safety, ESD and F&G systems following the OpreX processes and workflows. This includes the use of Smart JB with Universal, Safety N-IO and configurable cabinets. Hardware follows the same application independent process as the DCS and can be shipped as needed for construction. Application development also follows the same modular development process and remote, continuous testing process previously described.
Functional Safety Management (FSM)
FSM is essential for the SIS project execution and it aims to reduce hazardous impact to human life, environment, and property to a socially acceptable risk level throughout a plant’s safety life-cycle. Yokogawa is applying FSM to the realization of Safety Solutions in accordance with the international standards IEC-61508 and IEC-61511. This is achieved by rigorous application of Yokogawa global procedures coupled with independent certification by the internationally respected TÜV Rheinland organization.

Commissioning Support Package (F-CSP/PRM CSP)
Early devices and electronic check and site engagement are possible using Yokogawa’s N-IO and Filed – Commissioning Support Package (F-CSP). F-CSP performs N-IO node configuration and Input/Output validation and HART parameter download without the controller present. F-CSP validates the physical side of the field device and IO connection. PRM CSP Commissioning Support Tool can perform loop check automatically for HART devices through field control station. It is the tool supporting the works of connection, loop, range, engineering unit, signal conversion and interlock check for field digital field devices (HART and FOUNDATION Fieldbus H1) during commissioning phase and aims to achieve to:

- Reduce of commissioning time for field devices and its cost
- Improve the quality of commissioning of field devices
Flexible Binding (F-CSP with AD Suite)
Once the field information is validated by use of the Commissioning Support Package, it is reflected back into the system engineering database. The reflected database automatically binds into the application software. This is known as flexible binding which:

Fig.Late Binding vs Flexible Binding Image Zoom
- Allows for early shipping of Field Enclosures
- Facilitates early completion of field work without requiring the entire system to be ready at site.
- Enables flexible binding with DCS/SIS at any stage of SAT.
- Enables smoother commissioning and start-up.
- Accommodates late changes
The system has the full capability to accommodate any late modification and late change without compromising the overall project schedule.
Process Simulator (LCDS)
Dynamic Process Simulation has evolved over recent years. This has enabled simulation technology and a Life-Cycle Dynamic Simulator (LCDS) to be widely applied. The primary deliverables of LCDS throughout the project life-cycle are:
- Dynamic Process Simulation Model - Development of the process plant dynamic simulation model
- ICSS configurations & integration - Integration of the dynamic process model with an emulation of the automation system configuration
- ICSS Checkout - Testing with pre-defined operating scenarios (start-up, operations, abnormal conditions, alarm management)
- Operator Training – Testing of new ICSS platform, Standard Operating Procedure (SOP) validation and competency verification for initial and refresher training
LCDS deliverables can be progressively developed, used, re-used, and enhanced throughout the design & build and operation & maintenance phases of the project.

Foundation for Life-Cycle Management
Once the project has been turned over to the operations team, the OpreX methods provide the foundation for a sustainable plant all of the automation systems in the plant. A sustainable plant is Yokogawa‘s concept to maintain and improve the installed automation system providing a safe, secure, and robust installation at the lowest possible lifecycle cost.
