中控系统Integrated Control & Safety System(ICSS)

一套

1、中控系统的设计寿命应为30年。

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

2、PCS、FGS和ESD之间以及整个系统之间的通信速度不低于100Mbps。操作站、工程师站、PCS、ESD、FGS系统控制器之间的通信速率为100M，网络介质为冗余TCP/IP控制网络。当系统配置有多个操作站时，每个操作站应能够直接从每个PCS、ESD和FGS控制器获取数据，并且每个操作站应能够同步更新数据。当系统处于服务器-客户机体系结构中时，应该有独立的冗余服务器，不能与工程师站或操作员站共享。

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必须满足IEC61508和IEC61511的要求，FGS需要满足IEC 61508和NFPA 72的要求，安全等级应满足SIL3的要求（可寻址火气盘应满足SIL2）。投标人提供的ESD和FGS系统硬件和系统应具有安全认证机构（如TüV）颁发的安全认证。SIL 3认证系统应包括系统软件、硬件和安全控制网络，如控制器模块、I/O模块、通信模块、数据通信总线和与操作员工作站和工程师工作站上配置的安全控制系统相关的软件。ESD和FGS系统SIL 3应通过权威测试获得认证。

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.
