SM811K01 ABB 冗余模块 可以实现高完整性功能

SM811K01 ABB 冗余模块 可以实现高完整性功能 

CPU主板包含微处理器和RAM、实时时钟、LED指示灯、启动按钮和紧凑型闪存接口。

PM865控制器的底板有两个RJ45以太网端口(CN1、CN2)用于连接到控制网络，还有两个RJ45串行端口(COM3、COM4)。其中一个串行端口(COM3)是带有调制解调器控制信号的RS-232C端口，而另一个端口(COM4)则被隔离并用于连接配置工具。控制器支持CPU冗馀以实现高可用性(CPU、CEX总线、通信接口和S800 I/O)。

通过添加SM81x模块和SIL认证软件可以实现高完整性功能。这使得非关键控制方案能够通过添加SM81x模块和选择适当的软件升级到SIL认证方案。AC 800M高完整性还提供IEC 61508和TUV认证控制环境，用于在单个控制器单元中结合安全和业务关键型流程控制，而不牺牲安全完整性。

AC 800M高SIL 2认证使用PM865/SM810/SM811或PM867/SM812
AC 800M High SIL 3认证使用PM865/SM811或PM867/SM812
S800 I/O高完整性支持(PM865、PM866A和PM891)
控制器可配置为800xA control builder
控制器已获得完整的EMC认证
TUV认证SIL 2和SIL 3
内置冗馀以太网通信端口

The CPU motherboard contains a microprocessor and RAM, a real-time clock, LED indicators, a start button, and a compact flash interface.

The baseplate of the PM865 controller has two RJ45 Ethernet ports (CN1, CN2) for connecting to the control network, and two RJ45 serial ports (COM3, COM4). One of the serial ports (COM3) is the RS-232C port with the modem control signal, while the other port (COM4) is isolated and used to connect to the configuration tool. The controller supports CPU redundancy for high availability (CPU, CEX bus, communication interface, and S800 I/O).

High integrity functionality can be achieved by adding the SM81x module and SIL certification software. This enables the non-critical control scheme to be upgraded to the SIL certification scheme by adding the SM81x module and selecting the appropriate software. The AC 800M High Integrity also provides IEC 61508 and TUV certified control environments for combining security and business-critical process control in a single controller unit without sacrificing safety integrity.
