Alarm Analysis (Exaplog)

A process event analysis package that helps plants operate at optimal efficiency

새로운 Exaplog Event analysis package를 사용하면 DCS 이벤트 로그의 문제를 정량적으로 분석할 수 있습니다. 알람 설정 조정 및 작업 순서 조정으로 번갈아 분석함으로써 운영 효율성을 지속적으로 향상 시킬 수 있습니다.

Exaplog를 사용하면 "3W"(When, Where, What) 필터를 사용하여 이력 로그를 분석하여 여분의 알람을 식별 및 제거하고 작동 순서를 개선할 수 있습니다.
Exaplog는 관리자, 엔지니어 및 운전원이 공정 효율성을 향상시키는데 도움을 줍니다.

  1. Event Balance Trend "EBT" Graph Window (When?)
    공정 요청(공정 알람, 연산자 메시지)과 연산자 조치의 균형을 보여주는 트렌드 그래프를 표시한다. 필터를 사용하여 그래프의 어느 부분을 확대할 수 있습니다.
  2. Message Summary Window
    발생 순서대로 이벤트(카테고리 및 상세정보)를 표시합니다.
  3. Category Sort Window (What?)
    카테고리 별로 정렬된 이벤트(예 : 알람 공정 상태 변경)는 원형 차트 또는 표로 표시됩니다.
  4. Point ID Sort Window
    태그 이름과 스테이션 ID를 사용하여 빈도 별로 정렬된 이벤트를 표시합니다.

R3.40 Overview of the New Functions (September 2011)

  1. New software environments added
    Windows Server 2008 R2 Standard Edition SP1 (64-bit)
    Windows 7 Professional Edition SP1 (64-bit) supports added.
  2. Common IT security tool with CENTUM VP R5.01 added
    A user can select suitable security level from standard or legacy model. These IT security levels are common throughout Yokogawa system products, and it enables Exaplog to have the same IT security as the CENTUM VP. (Exaplog R3.40's IT security tool is as the same as CENUM VP R5.01.)

R3.30 (March 2010)

Support for:

  1. IT security
    Several security models (legacy, standard, and strengthened types) will be available, so that users will be able to select the security level to match their requirements.
  2. Tag comment display function
    A tag comment display function is added to the event identifier table on the PLView (event analysis tool) screen. This function increases the efficiency of the alarm analysis work.
  3. Windows Server 2008 SP2, Windows Vista Business Edition SP2

R3.20 (July 2008)

  1. CENTUM VP for events gathering
    As an Exaplog Adapter Type, CENTUM VP is added for events gathering. CENTUM VP Adapter gathers events from HISTHIST file on HIS.
  2. Automatic Deletion of Exaplog Event Files
  3. Supporting Microsoft Windows Vista Business Edition SP1

R3.10 (August 2006)

  1. Extended Function
    Period to display PLView event data, No. of displayed PLView event data, No. of saved event data
  2. Support for Windows Server 2003 Standard Edition SP1, R2
  3. Supported other companies' PCSevent data
Overview:
  • Operational Excellence by Asset Maximization, Utilizing Yokogawa's DCS, SIS, Analyzers, and Field Instruments.
  • The CENTUM VP PCS and ProSafe-RS SIS were integrated using the same engineering environment.
  • Nearly 60 gas chromatographs and a large number of other types of analyzers in several analyzer houses.
Overview:
  • Realization of current and historical data viewing and storage
  • Achievement of easy measurement of alarm load and in-depth alarm analysis
Overview:

Thai Acrylic Fibre Co., Ltd. (TAF) was established in 1987 and is currently a leading acrylic fiber manufacturer in the ASEAN region with 450 employees. It produces a wide range of acrylic fiber productions with varied deniers and the annual production recorded 77,000 megatons in 2004 which is five times the production rate at the time of establishment.

Overview:

Alarm management is not just a project that has a start and end date; it's a continuous cycle. Once the alarm system has been reviewed and improvements have been identified, we must check that controls are in place to ensure the alarm system remains functional. The key is to ensure that the system is continuously monitored and any changes are fully documented. There are seven key steps for alarm management. Rationalization is one of those critical steps.

Overview:

September 2007

Yokogawa's web-based DCS Anywhere has simplified commissioning at the Nanhai petrochemicals complex. With a total investment of 4.2 billion US dollars, the Nanhai petrochemicals complex at Daya Bay in Huizhou, China, has attracted a lot of attention because of its sheer scale.

Overview:

Large process industry companies have recently started building plants with world-class safety and profitability to reinforce their competitive edge in the global market. As for plant operations, support functions for improving operators' plant operation skills and for extending operators' maximum capability are required to the DCS so that an operator can expand the area of plant monitoring or operate a plant with higher cost- consciousness.

Yokogawa Technical Report
Overview:

As plant operation becomes more intelligent and complex, the alarm system for safe and stable operation is becoming increasingly important. An alarm warns operators of an abnormal situation in a process and urges them to respond to it.

Overview:

In recent years, safety and profitability have become ever more important in the process industry due to fierce global competition. Greater emphasis is being placed on highly efficient plant operation for reducing the increasing energy bill.

Yokogawa Technical Report
Overview:

In 1999, Yokogawa Electric Corporation formed an alliance with Shell Global Solutions International B.V. (SGSI) in Advanced Process Control (APC), and both companies have since jointly developed products. This alliance successfully combined SGSI's experience gained through more than 800 projects in more than 30 years and Yokogawa's great deal of experience with the process control market, and strengthened the scheme to provide the APC technology.
