振荡器监督
•固件和数据存储的CRC
SM811与SIL2的SM810类似，但也可与PM865一起使用
根据IEC61508，形成符合SIL3的控制器，由TÜV认证。
S800高的高完整性系统中使用的ModuleBus报文
完整性模块使用长框架的概念。长框架是模块总线
通过安全标题扩展的电报，包括附加诊断
数据和CRC32.S800模块总线报文发送至S800 I/O高完整性
模块使用来自PM865的数据和来自
SM810/SM811。输入/输出模块检查安全头是否正确。数据
通过模块总线从S800 I/O高完整性模块接收
由SM810/SM811和PM865独立验证的安全头。任何
CRC32或安全标题中的其他故障将导致重试传输，如果
重复关闭故障S800 I/O高完整性模块。
控制软件
AC 800M控制器使用的软件称为控制软件。
此名称不代表特定软件包；只是一个通用名称
用于控制器中使用的功能范围。这些功能由以下部分提供：
•硬件功能（监控、通信总线、I/O总线）
•加载到控制器中的固件功能（实时执行系统，实时
时钟，冗余通信）
•加载到控制器中的应用程序（库函数，
通信协议）。
要生成应用程序，必须使用Control Builder M工具。这
该工具非常通用，除了系统外，还具有许多有用的功能

Oscillator supervision
• CRC on firmware and data storage
An SM811 operates like an SM810 for SIL2 but can also together with the PM865
form a controller compliant with SIL3 according to IEC61508, certified by TÜV.
The ModuleBus telegrams used in a High Integrity system with the S800 High
Integrity modules use the concept of long frames. Long frames are ModuleBus
telegrams that are extended with a safety header, comprising additional diagnostics
data and CRC32. S800 ModuleBus telegrams sent to the S800 I/O High Integrity
modules uses data from the PM865 and an inverted CRC32 from the
SM810/SM811. The I/O module checks that the safety header is correct. Data
received from the S800 I/O High Integrity modules over the ModuleBus have the
safety header independently verified by both SM810/SM811 and PM865. Any
CRC32 or other faults in the safety header will result in a retry transmission and, if
repeated, a shutdown of the faulty S800 I/O High Integrity module.
Control Software
The software used by the AC 800M Controller is named Control Software.
This name does not stand for a specific software package; is merely a generic name
for the scope of functions used in a controller. These functions are provided by:
• Hardware functions (supervision, communication buses, I/O buses)
• Firmware functions loaded into the controller (real time executive system, real
time clock, redundant communication)
• Application programs loaded into the controller (library functions,
communication protocols).
To produce an application, it is necessary to use the Control Builder M tool. This
tool is extremely versatile, having many useful functions in addition to system
configuration.
Ethernet Address for PM8xx (Except PM891) Section 1 Introduction
52 3BSE036351-510 A
Ethernet Address for PM8xx (Except PM891)
Each TP830 Baseplate is provided with a unique Ethernet address that provides
every CPU with a hardware identity.
This functionality takes the form of two identification addresses residing in the
non-volatile memory of the TP830 Baseplate. The lowest address (a 12 character
Hex code) is located on an adhesive label attached to the TP830 Baseplate. The
remaining address is the lowest +1. See Figure 14 on page 53 for label location
details. See software documentation for details on loading the software and using
Ethernet address.

Ethernet Address for PM891
Each PM891 unit is provided with a unique Ethernet address that provides hardware
identity to the unit.
This functionality takes the form of two identification addresses residing in the
non-volatile memory of PM891. The lowest address (a 12 character Hex code) is
located on an adhesive label attached to the cover of PM891 unit. The remaining
address is the lowest +1. See Figure 15 on page 55 for label location details of
PM891. See software documentation for details on loading the software and using
Ethernet address.
