Setting SIL-Levels
设置SIL 等级
You can set Non-SIL, SIL1-2, and SIL3
for the Safety Level on Function
Blocks, Control
Modules, SingleControlModules, Programs, Diagrams, Applications,
and Tasks
according to the requirement.
你可以根据环境为功能块、控制模块、单个控制模板、程序、图表、用用程序和任务的安全等级
设置Non-SIL, SIL1-2, 和
SIL3。
Right-click on the object (except for tasks
where the setting is performed in the
Task Dialog),
select Properties, and then select Safety Level as shown in Figure
72. Select
the required SIL Level.
右键点击对象(在任务对话框中执行设置的任务除外),选择属性,然后选择安全级别,如图72所示,选择需要的SIL级别。
Figure 72. Setting SIL-Level
图 72. 设置SIL等级
The SIL-level is displayed as a black
number on top of the icon for the
intended object.
If no number is displayed the level is Non-SIL. This marking is
also available on Functions.
在于其对象图标顶部显示SIL等级的黑色数字。如果没有数字显示,是非SIL等级。此标记也可用于functions
Restricted SIL-Level
受限制的SIL的等级
It is
not allowed to use output parameters from Function Blocks or
Control Modules marked with Non-SIL in the parameter
description in a way that can influence
the safety
function of a SIL classified application. If such code affects an
output from a SIL3 application, it might result in a Safety
Shutdown.
不允许在参数描述中使用标有非 SIL 的功能块或控制模块的输出参数,以免影响 SIL
分类应用的安全功能。
如果此类代码影响 SIL3
应用的输出,则可能导致安全关断
Some
of the objects and functions in standard libraries have a
restricted SIL-marking for both SIL2 and SIL3 functions.
These functions are allowed to
be used in
a SIL application with few restrictions. Using a restricted object
or function to affect I/O or to be used in peer-to-peer
communication might result in
a malfunctioning
application or a safety shutdown.
标准库中的某些对象和函数对 SIL2 和 SIL3 函数都具有受限制的 SIL
标记。这些功能允许在SIL应用中使用,几乎没有限制。使用受限制的对象或函数来影响 I/O
或用于对等通信可能会导致应用程序故障或安全关闭。
Restricted objects and functions are identified
by a special icon in the project tree
in the Control
Builder project explorer. They must not be used as a part of the
critical loop for a safety function. The color of the
SIL-digit in the icon is grey on a restricted object and function, compared
to the black digit on regular SIL-classified objects and functions. Examples
of Restricted icons is as shown
in the
figure below.
受限制的对象和函数由Control
Builder 项目资源管理器中项目树中的特殊图标标识。它们不得用作安全功能的关键回路的一部分。图标中
SIL 数字的颜色在受限对象和功能上为灰色,而常规 SIL
分类对象和功能上的黑色数字则为灰色。受限制图标的示例如下图所示。
It is not allowed to use Functions,
Function Blocks or Control Modules marked
as SILxRestricted
in a way that can influence the safety function of a SIL
classified application.
不允许以可能影响 SIL 分类应用安全功能的方式使用标记为 SILxRestricted
的功能、功能块或控制模块。
High Integrity Controllers
高性能控制器
An
AC 800M High Integrity (HI) controller consists of a PM865 or
PM867 processor
unit and a number of HI-specific objects that are added to the
hardware tree, see Figure 73.
AC
800M 高完整性 (HI) 控制器由 PM865 或 PM867 处理器单元和许多添加到硬件树中的特定于 HI 的对象组成,请参见图
73。
Figure 73. AC 800M High Integrity controller
图 73. AC 800M高性能处理器
The following objects are only added for a HI
controller:
下面的对象仅为高完整性控制器添加
- SM81X (1) is a module that supervises the function of the controller.
SM81X(1)是监控控制器的模块
- The VMT task (2) is used to run the VMT application. Note that the VMT application is connected to HI controllers automatically, and should not be removed.
VMT 任务 (2) 用于运行 VMT 应用程序。请注意,VMT 应用程序会自动连接到 HI
控制器,不应将其删除。
- The VMT application (3) (see previous subsection) is automatically connected to the controller.
VMT 应用程序 (3)(参见上一小节)会自动连接到控制器。
In addition to the objects listed above, a High Integrity
controller also has HIspecific firmware, which makes sure that the controller
works as specified in the SIL1-2 and SIL3 standard.
除了上面列出的对象外,高完整性控制器还具有特定于 HI
的固件,可确保控制器按照 SIL1-2 和 SIL3 标准中的规定工作。
Downloading an Application
下载应用程序
Access Enable must be set to (ON) before downloading
to an AC 800M HI controller, no matter if the applications are
non-SIL or SIL marked.
在下载到 AC 800M HI
控制器之前,必须将访问启用设置为 (ON),无论应用程序是非 SIL 还是 SIL 标记。
附录C到此u恶习完毕。这一章内容只有在有SIL的时候才需要用到,有点绕,后面再花点时间好好理解一下。
