中控系統Integrated Control & Safety System(ICSS)

一套

1、中控系統的設計壽命應為30年。

The design life for the ICSS should be thirty (30) years.

2、PCS、FGS和ESD之間以及整個系統之間的通信速度不低于100Mbps。操作站、工程師站、PCS、ESD、FGS系統控制器之間的通信速率為100M，網絡介質為冗余TCP/IP控制網絡。當系統配置有多個操作站時，每個操作站應能夠直接從每個PCS、ESD和FGS控制器獲取數據，并且每個操作站應能夠同步更新數據。當系統處于服務器-客戶機體系結構中時，應該有獨立的冗余服務器，不能與工程師站或操作員站共享。

The communication speed must be at least 100Mbps among the PCS, FGS and ESD and among the whole system. The communication rate between the operation station, engineer station, PCS, ESD, and FGS system controller is 100M, and the network medium is a redundant TCP/IP control network. When the system is configured with multiple operating stations, each operating station should be able to obtain data directly from each PCS, ESD, and FGS controller, and each operating station should be able to update data synchronously. When the system is in a server-client architecture, there should be independent redundant servers that cannot be shared with engineer or operator stations.

3、ESD必須滿足IEC61508和IEC61511的要求，FGS需要滿足IEC 61508和NFPA 72的要求，安全等級應滿足SIL3的要求（可尋址火氣盤應滿足SIL2）。投標人提供的ESD和FGS系統硬件和系統應具有安全認證機構（如TüV）頒發的安全認證。SIL 3認證系統應包括系統軟件、硬件和安全控制網絡，如控制器模塊、I/O模塊、通信模塊、數據通信總線和與操作員工作站和工程師工作站上配置的安全控制系統相關的軟件。ESD和FGS系統SIL 3應通過權威測試獲得認證。

ESD must meet the requirements of IEC61508 and IEC61511, FGS must meet the requirements of IEC 61508 and NFPA 72, and the safety level should meet the requirements of SIL3(the ADDRESSABLE FIRE and GAS PANEL shall be SIL2). ESD and FGS system hardware and system provided by seller shall have safety certification issued by safety certification authority (such as TüV) The SIL 3 certificated system shall be included system software, hardware and safety control network, such as controller modules, I/O modules, communication modules, data communication bus and the software relative with safe control system configured on the operator workstations and engineer workstations. ESD and FGS system SIL 3 shall be supplied certificate through Authority test.
