  • WEL - COME TO DISTRIBUTED CONTROL SYSTEM (DCS)
  • What is DCS ?  DCS is abbreviation for Distributed Control System  As is apparent from the abbreviation, the word ‘Distributed’ supports following functionality’s  Physical Distribution - Nodes or Subsystems can be Distributed I.e located physically apart  Functional Distribution - Specific Functionality is imparted for a Node basing on the combination of hardware and software used. For e.g Application work-processor with Historian, Application work- processor with control configuration software  Structural Distribution - Different Structural hardware platforms (Application Workstation processor, Workstation processor, Control processor etc.) are used to achieve the required functionality.
  • WHY DCS ?  For Total Plant Automation  For Higher Productivity  For Optimal Process Control  For Regulatory Compliance  For Management Information System  In Tune With Global Requirement
  • DCS MANUFACTURERS  HONEYWELL  YOKOGOWA  ALLEN BRADLEY  GE FANUC  EMERSON  ASEA BROWN BOWERI – ABB  FOXBORO - INVENSYS
  • What DCS we are using?  Emerson Delta V system
  • Overview of Delta V system Engineering station Operator station Application station Controller and IO Controller and IO
  • Professional PLUS (Engineering) Workstation  Every DeltaV system must have one, and only one, Professional PLUS Station. It provides the global configuration and the configuration database for the system. Therefore, it is the primary engineering and configuration interface for a DeltaV System. For small DeltaV systems, it also serves as the operator and diagnostics interface for the system. PROPLUS STATION
  • Application (PI Historian) Workstation  This Application Station provides integration between your DeltaV system and the rest of your day-to-day operations, using OLE for Process Control (OPC). Optionally, you can extend your DeltaV system with DeltaV applications and other third-party applications tailored for your particular process. It is also act as a PI Historian server. APPLICATION STATION
  • Delta V controller  The CONTROLLER manages all control activities for the I/O interface channels. It also manages all communication functions for the communications network. Time tamping, alarming, and trend objects are also managed within the controller. The controller executes your control strategy. Information from an input channel is received, control strategy applied, and data sent to an output channel within 100 ms.  The DeltaV I/O subsystem is comprised of the following components:  Carriers  Power Supplies  Controller  I/O Modules
  • Operator workstation  For workstations that are required for operating the process and viewing continuous history only, select the Operator Station Software Suite. Applications typically added to the Operator Station Software Suite are the Event Chronicle, Diagnostics, and Control Studio On-Line. OPERATOR STATION

  • OPERATOR WORK STATION FUNCTIONS AND FEATURES
  • OPERATOR STATION OVERVIEW
  • OPERATOR STATION BUTTONS1 Buttons Acknowledge Alarm - This button is displayed in the Alarm Banner. It also appears in the faceplate and detail displays for the standard modules. If you select this icon in the Alarm Banner, the system acknowledges all the unacknowledged alarms in the main process graphic. Only those alarm parameters that are part of the graphic are acknowledged. Silence Horn - This button stops the horn. If new alarms become active, the horn sounds again.
  • OPERATOR STATION BUTTON2 Buttons Alarm Suppress - This button is displayed in the Alarm List picture and the Alarm Filter picture. Clicking the Alarm Suppress button opens the Operator Suppressed Alarm picture, which lists all of the suppressed alarms. Diagnostics - This button is displayed in the Alarm banner. It shows your Communications status. The Diagnostics button displays two indicators for the Primary Communications network and four indicators for the Secondary Communications network. Clicking the Diagnostics button launches diagnostics, which provides more detailed information.
  • OPERATOR STATION BUTTONS3 Buttons Disable Horn/Enable Horn - When disabled, new alarms do not cause the horn to sound. This setting is a parameter of the current user's session. When a new user logs on, the horn is enabled. Node Status - This button is displayed in the Alarm banner. This button is not displayed if Batch Operator Interface is running. Clicking the Node Status button launches the Node Status picture, which provides information on your node (for example, current status and time of last status change or download as well as whether or not its alarms have been acknowledged).
