PlantPAx系统支持可伸缩的解决方案,可以满足特定的可用性和安全性需求。
? ControlLogix控制器能够满足SIL 1和SIL 2要求。
? GuardLogix 控制器能够满足SIL 3的要求。
? ICS Triplex Trusted 控制器支持三重模块冗余,可伸缩AADvance
控制器在单一、双重或者三重化配置时,具有支持SIL 1, 2, 和3 能力。 所有ICS 三重化解决方案都支持CIP功能,是罗克韦尔自动化集成架构的一部分。
对独立型架构进行扩展,按照不同角色增加工作站,就构成了集中型的控制系统。集中化型的架构用于具有多个过程单元的应用,覆盖较大的物理区域,需要多个OWS。集中式系统增加了诸如***数据收集(历史)、复杂批处理控制、管理和基本制造执行系统(MES)互联等能力。
集中式系统是一种多客户机配置,支持单一生产线或者过程的自动控制。系统组件可以在主控制室运行,操作员站可以安装在生产线的附近。集中式系统是根据独立系统而扩展,增加了:
? 的过程自动化系统服务器(PASS),用作中心人机界面(HMI)服务器(可选一个冗余服务器对)。
? 工程师站(EWS),用于开发和维护整个系统,包括系统安全。
? 多个操作员站(OWS),用做交互式图形界面。
? 用于服务器,用于批处理管理、数据采集(历史)或者变化管理(资产管理)。
集中式系统支持下面系统组件:
? 一个PASS。
? 多八个OWS。
? 六个过程控制器,每个控制器可执行125个复杂调节控制策略(回路),系统大支持500个控制策略。
? 每个控制器可以连接64个I/O模块,包括ControlNet网络上的远程I/O。
? I/O组件可以是各种类型的I/O,名义上,每个控制器在分布式情况下,可以控制1024点:
– 250 个模拟量输入(4...20 mA 或者HART设备);
– 125 个模拟量输出(4...20 mA 或者HART设备);
– 400 个数字量输入;
– 200 个数字量输出;
– 4 个特殊模块(诸如Foundation Fieldbus 链接设备、Profibus PA网桥,或者DeviceNet 网桥)。

Safety control system is a control system specially used for interlocking and emergency shutdown in dangerous places (such as petrochemical plants). The essential difference between it and DCS and PLC of ordinary process control is that its function is to make the device stop safely under accident and fault conditions (including device accident and control system failure), so as to avoid disaster, that is, to avoid injury to device personnel and impact on the environment. Therefore, the safety control system itself must be fail to safe, The reliability of the hardware and software of the system is very high. In the international safety standard IEC61508, there are detailed provisions on the requirements of safety level and safety control system. T ? V is the only safety control system certification body in the world at present.Since hima first launched the t ? V certified fail safe safety control system hima planar system in 1970, the safety control system has a development history of 30 years.
Development history of hima safety control system:
In 1970, hima launched the world's first t ? V certified fail safe control system hima planar system and put it into use.
In 1983, hima launched the world's first fail safe programmable electronic control system (PES) for safety control.
In 1986, hima launched the world's first programmable safety control system H50 certified by t ? V and put it into use. The CPU structure is double redundant fault-tolerant full self diagnosis type, that is, 1oo2d.
In 1991, hima launched the second generation of t ? V certified PES system h51 and H41 series products
In the late 1980s and early 1990s, other manufacturers of safety control systems emerged one after another, and the technology adopted is generally 1oo2d or 2oo3 voting (TMR) technology, which is still used today.
In 1997, hima launched the world's first A-type system product with quad (QMR) CPU structure certified by t ? V, namely 2oo4d.
In 1998, hima launched the third generation of t ? V certified PES systems h41q and H51q, which adopt Quad CPU structure, namely 2oo4d. CPU structure of programmable (PES) safety control systemAt present, the programmable safety control system that conforms to iec-61508 standard and has obtained t ? V ak6/sil3 level certification in the world has the following three mainstream CPU structures:
Double redundant fault-tolerant complete self diagnostic structure, i.e. 1oo2d structure.
