\u05d5\u05dc\u05d9\u05d3\u05e6\u05d9\u05d4 –\u00a0Design Specification – DS<\/h2>\n

The Design Specification -DS<\/strong>\u00a0is part of the validation<\/a> documentation that provides information necessary to complete the design of the project. This document covers only the DCS side and integration with ELT-GHS-150-T3 Gas Heater skid<\/p>\n

DS Content<\/h3>\n

The DS is usually structured in a relatively standard fashion, with predetermined chapters and sections, where the final contents are tailored according to the type and size of the system under validation.<\/p>\n

:The main chapters and sections of this DS are<\/p>\n

Hardware Specification<\/p>\n

Wiring and Electrical Cabinet Drawing<\/p>\n

Communication and Network Design<\/p>\n

Other Documentation<\/p>\n

<\/a> ProfiBus Monitoring Values List<\/p>\n

<\/a><\/a><\/a> Running Logic<\/p>\n

<\/a> Alarms List<\/p>\n

<\/a><\/a> Alarm Response<\/p>\n

<\/a><\/a> Disaster Recovery<\/p>\n

<\/a> Programming Design<\/p>\n

Appendixes<\/p>\n

Hardware Specification<\/h3>\n

.This section defines the required I\/O allocation, according to the wiring diagram document No. P09204-020 Rev2, and 35800SIS0-N0<\/p>\n

8 digital inputs<\/p>\n

1 digital outputs<\/p>\n

ProfiBus connection<\/p>\n

Wiring and Electrical Cabinet Drawing<\/p>\n

:This section lists the following design information<\/p>\n

New Electrical drawing is not needed<\/p>\n

:All I\/O should be named in a standard fashion, i.e., XXXX-YYY-ZZZ, where<\/p>\n

XXXX – 4 prefix letters which indicates the containing system; in this case, the system is PRMS<\/p>\n

.YYY – indicates the instrument type according to Siemens<\/strong> naming standard \u2013 document no<\/p>\n

ZZZ – indicates the serial continuing number<\/p>\n

.Siemens<\/strong> Engineering file update is needed in Chapters18C 18D 18E. Other chapters should be examine and discussed in the FRS<\/p>\n

.BOP PLC must be stopped during the wiring and ProfiBus module installation. Dalkia should be supply with time table<\/p>\n

Communication and Network Design<\/h3>\n

:This section lists the following design information<\/p>\n

.The communication used in this project is Profibus<\/p>\n

.The Profibus communication protocol and wiring design will be provided by Siemens<\/p>\n

.Siemens Engineering file update is needed. All communication and network chapters should be updated<\/p>\n

Communication and Network Design<\/h3>\n

Siemens Engineering file "stand alone skids and instruments" chapter should be update; all Heater manuals and instructions should be attached to this chapter.<\/p>\n

ProfiBus Monitoring Values List<\/h3>\n

  2. Compressed air supply shut down<\/li>\n<\/ol>\n

    \u00a0Programming Design<\/h3>\n

    AS (Automation system \u2013 PLC) that will be programmed in this integration will be BOP.<\/p>\n

    The synoptic screen will be programmed and be added to the PRMS screen, as described in Appendix 1 \u2013 Synoptic Screen.<\/p>\n

    All instruments, EG valves and transmitters, will be created according to Siemens<\/strong> standards.<\/p>\n

    All instruments will be set to READ ONLY, except the START and STOP buttons.<\/p>\n

    Appendixes<\/h3>\n

    The DS<\/strong> appendixes present examples of design drawings.<\/p>\n
