CI871 ABB 冗余系列PLC系统 分布式控制系统

CI871 ABB 冗余系列PLC系统 分布式控制系统

CI871A 是 AC 800M 通信接口，通过以太网连接到 PROFINET IO 设备。TP867 底板有两个 RJ45 以太网连接器，但只有支持 100Mbps 的 CH1 连接器用于 PROFINET IO 连接。以太网电缆必须通过以太网交换机连接到 PROFINET IO 网络。

CI871 扩展单元包含 CEX 总线逻辑、通信单元和 DC/DC 转换器，该转换器通过 CEX-Bus 从 +24 V 电源提供所需的电压。

CI871A 模块仅适用于 System 800xA 6.0.3.3、6.1.1 及后续版本

高可用性特性

而AC 800M系列控制器涵盖行业和应用范围，许多控制器都有附加的功能和高可用性特性关键的应用程序。

冗余在I/O，控制器和通信级别是可选的，大灵活性和可用性。系统800xA操作、工程和其他应用程序与AC 800M控制和I/O进行通信相同的可选冗余以太网控件网络。

如果—次电路发生故障，则无颠簸转移到备份确保不受干扰

操作。实现所有冗余选项消除单点故障，从而有所帮助确保大可用性。

高完整性

AC 800M HI控制器，PM857,PM863和PM867，提供认证的TUV控制环境

为工艺安全应用于—体以及立环境。

采用交流800MHI控制器，在与一个多样化的协处理器，SM812，执行诊断和应用程序执行监控l/O扫描。

HI控制器提供了灵活性网络设计，因为他们可以用于综合但立的安全操作或完全将安全性和关键业务流程控制结合在一起的集成应用程序控制器不牺牲安全完整。

SIL 3级，iec61508认证AC 800M Hl控制器非常适合任何一种。

The CI871A is an AC 800M communication interface that connects to the PROFINET IO device over Ethernet. The TP867 baseboard has two RJ45 Ethernet connectors, but only the 100Mbps CH1 connector is used for PROFINET IO connectivity. The Ethernet cable must be connected to the PROFINET IO network through an Ethernet switch.

The CI871 expansion unit contains the CEX Bus logic, a communication unit, and a DC/DC converter that delivers the required voltage from a +24 V power supply via the CEX-BUS.

The CI871A module is only applicable to System 800xA 6.0.3.3, 6.1.1 and later versions

High availability feature

While the AC 800M series controllers cover a wide range of industries and applications, many controllers have additional features and high availability features for critical applications.

Redundancy at the I/O, controller and communication levels is optional, with great flexibility and availability. System 800xA operations, engineering and other applications communicate with AC 800M control and I/O in the same optional redundant Ethernet control network.

If a circuit failure occurs a second time, there is no turbulence transfer to the backup to ensure no interference

Operate. Implementing all redundancy options eliminates a single point of failure, which helps ensure high availability.

High integrity

AC 800M HI controllers, PM857,PM863 and PM867, provide certified TUV control environments

For process safety applications in both physical and vertical environments.

The AC 800MHI controller, in conjunction with a diverse coprocessor, the SM812, performs diagnostic and application execution monitoring l/O scans.

HI controllers offer flexibility in network design as they can be used for integrated yet standalone security operations or integrated application controllers that fully combine security and critical business process control without sacrificing security integrity.

SIL Level 3, iec61508 certified AC 800M Hl controllers are ideal for either.
