问题标签 [open62541]

我在这里发布这个是因为我确信这不是一个错误，它只是我的测试配置没有正确设置，但我无法指出我做错了什么。

我安装单个文件版本： https ://open62541.org/releases/

连同 open62541 的构建环境，然后构建并运行本教程： https ://github.com/open62541/open62541/blob/master/examples/tutorial_server_variable.c

使用这些命令：

但是，当我通过匿名登录与 UA 专家联系时，我无法看到每个示例中添加的任何变量。我确实看到并且能够订阅几个默认服务器参数。非常感谢任何可以解释为什么我没有看到变量的人。我相信它们应该出现在左窗格导航器的“对象”文件夹下。 ua 专家是版本 1.4.4 275

这是服务器的控制台输出：

我编写了一个 OPC UA 客户端，我正在使用 ProSys OPC UA Simulator Server 对其进行测试。我的客户端以匿名模式运行，我可以浏览服务器。但是，当我将客户端配置为使用用户名和密码时，它会失败，并没有为可能的端点找到合适的 UserTokenPolicy。我已经对其进行了调试，似乎http://opcfoundation.org/UA/Se.....olicy#None不在端点 userIdentityTokens 数组中，尽管在 ProSys 中它声明它是。

我在 OPC UA Simulator 用户名和密码框中设置了一个用户 安全模式 = 无 安全策略 = 没有被勾选

服务器端点安全模式列表=无安全策略=无所以我希望在 userIdentityTokens 数组中看到它。

我的客户端是使用 Open62541 库编写的

任何帮助，将不胜感激。

谢谢

我参考此页面提供的文档，使用 open62541 架构构建了一个服务器 。命令提示符的以下输入gcc -std=c99 open62541.c myServer.c -lws2_32 -o myServer.exe生成可执行文件。该架构仅兼容 std c99 库，-lws2_32必须在命令中添加对 Winsock 库的引用，否则将不会生成可执行文件并产生链接器错误。

我成功地使用命令提示符生成可执行文件，现在我想使用应用程序“Visual Studio”/“Codeblocks”做同样的事情（生成服务器程序可执行文件），因为我想调试程序。

如何为 Visual Studio/Codeblocks 的编译器提供输入以明确包含 std c99 和 Winsock 库？是否有人成功迁移 open62541 以调试环境？

我一直在寻找有关如何面对我要解释的问题的信息，但不幸的是我无法解决它。

我想创建一个ObjectType ProgrammType 的对象程序，其中包含 ObjectType CommandType的实例数组。Programm对象中这些命令对象的顺序是相关的。

我正在使用 ModelDesign XML 文件来创建信息模型。关于我想要实现的信息建模，我已经看到有可能在ProgrammType定义中使用 ModellingRule“OptionalPlaceholder”，尽管说实话，这个 ModellingRule 的用法对我来说并不完全清楚。

所以到目前为止我所做的是将带有 ModellingRule “OptionalPlaceholder”的“CommandType”类型的对象作为子对象添加到ProgrammType定义中。然后，在实例化部分，我正在创建Command对象，最后我使用Programm对象中的“HasOrderedComponent”来引用它们。我不确定这种方法是否真的有意义，它是否利用了先前在ProgrammType定义中定义的“OptionalPlaceholder”。如果这不是他们正确的做法，请让我知道应该如何做。

据我了解，“HasOrderedComponent”引用意味着服务器始终以相同的顺序返回元素。

我从 ModelDesign XML 文件生成 UANodeSet XML 文件，然后我正在使用这个 NodeSet 创建一个 Open62541 服务器。

所以我的问题是：

1.) 我的建模方法对吗？有没有更好的方法来建模我在开始时描述的内容？

2.) 当我从基于 Open62541 的客户端检索时，在 Open62541 服务器的Programm对象中使用“HasOrderedComponent”引用的命令。

• 可以预测它们会按什么顺序出现吗？或者返回的顺序总是一样的，但是这个顺序不能设置。
• 它们会按照在 ModelDesign 文件中定义的顺序返回吗？
• 如果我从我编写的“手动”代码创建节点。命令的返回顺序是在我的代码中添加引用的顺序吗？

非常感谢您！顺便说一句，一旦我成功地对我正在做的工作进行建模，我就可以准备一个关于如何在 OPC UA 中建模的详细说明，如果您认为它可能相关，可以使用它来扩展 Open62541 文档。

此致

我是 OPC UA 的初学者，正在探索规范第 12 部分中提到的发现机制。我有几个疑问。

1. 在组播扩展发现中，服务器向其本地发现服务器（LDS ME）注册，当客户端向其LDS-ME注册时，客户端LDS-ME发出组播探测，服务器端LDS-ME响应带有公告，从而允许客户端知道网络中的服务器列表。我的问题是，为什么这个过程被称为多播探测和多播公告。因为根据 mDNS 规范，探测和公告最初用于确保资源记录的唯一所有权。任何人都可以告诉我为什么它被称为探测和宣布？

2. 在 open62541 堆栈中，使用发现示例，运行 server_lds.c，我收到一条日志消息“多播 DNS：出站接口 0.0.0.0，这意味着使用了第一个操作系统接口（您可以使用显式设置接口） 'discovery.mdnsInterfaceIP' 配置参数）”。现在理论说多播 dns IP 应该是 224.0.0.251: 5353 为什么它被设置为 0.0.0.0？有人可以告诉我吗？

问候， 罗山

经过数小时的互联网研究以寻求解决方案（我知道有一些类似的问题，但没有任何帮助），我差点认输，因此非常感谢您的帮助。

初步：我想将 C99 库open62541用于我自己的 C++ 项目。我为 PubSub 使用了足够的构建选项，因为这是我最感兴趣的。我还将安装路径配置为/home/user/install/open62541.

问题描述：起初我能够使用这个CMakeLists.txt构建所有内容。但目前我尝试将 open62541 的订阅功能添加到项目中，但 CMake 拒绝将库链接到项目中，因为它应该：

• 我将此示例代码从教程复制到项目中，add_executable(subscriber ${CMAKE_CURRENT_SOURCE_DIR}/tutorial_pubsub_subscribe.cpp)并添加target_link_libraries(subscriber PUBLIC open62541)到我的CMakeLists.txt中。
• CMake 抱怨以下问题：undefined reference to 'UA_PubSubConnection_regist'
• 然后我去我的安装路径的 lib 文件夹找到libopen62541.so和
• 使用 nm 命令检查共享对象nm libopen62541.so | grep UA_PubSubConnection_regist
• nm 返回 "t",

所以我想 open62541 的构建不能是链接错误的原因。

我试图了解类型转换在以下代码中的作用

这是 UA_Variant 的结构

这条线发生了什么

是否将 Variant 中的数据类型转换为 int32_t 然后将其指针放入变量中，如果是这样，为什么我可以打印出存储在变量中的值？

我在将 Raspberry Pi 上的客户端连接到 Raspberry pi 上的服务器时遇到了一点问题，希望你们对如何解决它有一些想法。

它们都已使用本指南 https://open62541.org/doc/current/building.html进行设置

为简单起见，我也使用了他们网站上的简单客户端和服务器设置，位于

https://open62541.org/doc/current/tutorial_client_firststeps.html

和

https://open62541.org/doc/current/tutorial_server_firststeps.html

唯一的区别是因为我使用的是 UA_ENABLE_AMALGAMATION 选项

已更改为

我得到的读数是

对于服务器和

为客户

我可以用 UaExpert 连接到两个树莓派，但由于某种原因，客户端不想连接？

任何想法可能导致此问题？

这些也是 Open62541 的当前配置

处理向客户端显示服务器状态信息（可用或忙碌）的需求。2种方法如下：

1. 使用服务器功能阵列的设施来显示信息。因为它是一个数组，所以第一个元素是服务器的特征，第二个元素是状态（初始可用）。服务器配置（多播服务器的最大会话更改为 1。发生这种情况时，功能数组的第二个元素更改为忙碌。但是，在运行客户端应用程序时（来自 open62541 发现示例的 findServersOnNetwork.c），这是未反映，因为配置参数的值是在服务器运行之前获取的（例如：始终可用状态）

2）使用相同的服务器能力阵列扩展，这一次，一旦建立会话，我取消注册服务器，将能力列表更改为忙碌并再次注册服务器。但这样做时，我收到一个错误：检测到多播 DNS 名称冲突：'Crane Multicast Server-._opcua-tcp._tcp.local。用于 16 型

我已附上成功注销（删除记录）的LDS日志。然而它显示了冲突。请让我知道这里可能是什么问题？尽管删除了记录，但冲突是不可接受的，对吧？

复制步骤：server_multicast.c（来自 open62541 堆栈的示例部分）

我正在尝试通过参考此页面提供的文档来使用 open62541 构建服务器。

我可以通过参考这个网页生成 open62541.c 和 open62541.h 文件。如前所述，我使用 CMake 和 VisualStudio 生成了这些文件。当我尝试编译 myServer.c 文件时，出现以下错误。

大多数错误描述未定义某些变量。我发现 UA_SOCKET 未在 open62541.h 或 open62541.c 文件中定义，但在文档中写到这两个文件足以构建服务器文件。

有人成功编译服务器文件吗？谢谢。
