What is an OPC UA Client?
An OPC UA Client is a tool that communicates with OPC UA Servers to retrieve, monitor, and update data. We provide a free OPC UA Client tool allowing users to test their OPC UA communications without restriction.
What OPC UA data models does the OPC UA Client support
The OPC UA Client supports the main OPC Unified Architecture models: Data Access, Alarms & Conditions, and Historical Access. Meaning, the OPC UA Client allows access to real-time data, alarms & conditions, and historical data from any compliant OPC UA server. It can monitor ongoing events and retrieve past information stored in the server.
What is the difference between OPC UA Client and OPC UA Server?
An OPC UA Server provides and manages the data. An OPC UA Client requests and accesses data from an OPC UA Server . The client consumes the data while the server supplies and organizes it.
How can I discover OPC UA servers using the OPC UA Client?
The OPC UA Client can discover OPC UA servers using OPC UA discovery server service
How does the OPC UA Client ensure secure communication?
The OPC UA Client can establish secure communication channels using encryption and authentication. It generates a self-signed Application Instance Certificate to secure connections with OPC UA servers, ensuring data integrity and security.
Can the OPC UA Client monitor real-time data and alarms?
Yes, the OPC UA Client can monitor real-time data such as sensor readings and process values, as well as alarms and conditions, allowing users to respond to operational issues as they occur.
How can the OPC UA Client interact with historical data?
The OPC UA Client can explore and update historical data, giving users the ability to query past information for analysis or make changes to stored data when necessary.
What are the prerequisites needed to install the OPC UA Client?
What are the prerequisites needed to install the OPC UA Client? Make sure that you have the following prerequisites available in your target machine:
- .NET Framework version 4. 6 or higher.
- The OPC UA Local Discovery Server, which lists the OPC UA endpoints available on a given computer. You can deploy it during the installation by checking the option “Install OPC UA Local Discovery Server” or after installation by using the setup available in the installation folder of the OPC UA Client.
The OPC UA Client can explore and update historical data, giving users the ability to query past information for analysis or make changes to stored data when necessary.
Are OPC UA methods supported in the OPC UA Client?
Yes, the OPC UA Client allows you to call OPC UA methods implemented in your OPC UA Server.The OPC UA Client can explore and update historical data, giving users the ability to query past information for analysis or make changes to stored data when necessary.
What is the OPC UA Server Simulator - Full Edition used for?
The OPC UA Server Simulator - Full Edition is designed for developers, system integrators, and end-users to simulate both real-time and historical data based on the OPC UA standard. It allows you to test and validate OPC UA Client applications, making it ideal for system testing, troubleshooting, and training.
What OPC UA data models does the simulator support?
The OPC UA Server Simulator - Full Edition supports data access and historical access information models. These allow clients to access real-time and historical data, which is vital for testing OPC UA communications.
How can I configure the tags and data in the OPC UA Server Simulator?
Users can configure their own tags and data simulation through CSV files. This allows for customizable and flexible simulation environments tailored to user specific testing needs.
Is there a free version of the OPC UA Server Simulator available?
Is there a free version of the OPC UA Server Simulator available? We do provide a free edition of the OPC UA Server Simulator, which is available
here.
The free edition supports 48 hours runtime. Meaning, it runs without interruption for 48 hours.
You will have to restart it after 48 hours in order to continue using the simulator.
Can the simulator run continuously without interruptions?
Yes, the full edition is designed to simulate real-time and historical data without interruption, making it a reliable tool for long-term testing and integration.
What are the data types supported by the simulator?
The simulator supports the following data types:
- Int16
- Int32
- Int64
- UInt16
- UInt32
- UInt64
- Double
- String
- Byte
- Boolean
What is an OPC UA Wrapper?
OPC UA Wrapper is a plug and play software product that enables users to
easily migrate to OPC UA. It includes 2 components:
-
The wrapper, to allow OPC UA clients to communicate with OPC Classic
servers. It supports OPC Data Access, OPC Historical Data Access and OPC
Alarms & Events servers.
-
The proxy, to allow OPC Classic clients to communicate with OPC UA
servers. It supports OPC UA DA, HA and AC capabilities.
What is an OPC UA proxy
The OPC UA Proxy is a feature component of the OPC UA Wrapper. It allows converting an OPC UA Server to an OPC Classic Server and consequently establishing communications between OPC Classic Clients and OPC UA Servers.
How is the OPC UA Wrapper licensed?
The OPC UA Wrapper license is a license per machine. License prices depend on the selected features. The available features are:
- OPC DA to OPC UA Wrapper
- OPC HDA to OPC UA Wrapper
- OPC AE to OPC UA Wrapper
- OPC UA to OPC DA Proxy
- OPC UA to OPC HDA Proxy
- OPC UA to OPC AE Proxy
Does the OPC UA Wrapper provide historical data access?
Yes, the OPC UA Wrapper can expose OPC historical data from OPC Classic HDA Servers to an OPC UA interface. This capability is especially critical for applications that need to analyze historical performance, track trends, and store data for an extended period but still depend on legacy OT systems.
Users can use historical data to make informed decisions based on past trends and patterns.
Can the OPC UA Wrapper support several servers at once?
Yes.Users can configure multiple OPC UA Wrapper services to execute at the same time. It supports connections to numerous local and remote OPC (DA/HDA/AE) servers per service, as well as multiple OPC UA servers.
How does the OPC UA Wrapper improve compatibility between OPC Classic and OPC UA Servers?
The OPC UA Wrapper improves compatibility by serving as a bridge between OPC Classic servers and OPC UA clients and vice versa
How can we trace operations performed by the OPC UA Wrapper?
The OPC UA Wrapper traces its operations via log files allowing users to effectively monitor system activities and troubleshoot issues if needed.
What operating system versions does the OPC UA Wrapper support?
The OPC UA Wrapper supports the following Windows OS versions:
- Windows 7
- Windows 8
- Windows 10
- Windows 11
- Windows Server 2012
- Windows Server 2016
- Windows Server 2008
- Windows Server 2019
- Windows Server 2022
What type of protocols does OPC UA Wrapper supports?
The OPC UA Wrapper supports two types of OPC UA communication protocols: TCP and HTTP, and supports the HTTPS transport protocol for the proxy feature.
Does OPC UA Wrapper limit the number of tags?
The OPC UA Wrapper does not include a limit on the number of tags or the number of connected OPC Servers.
Do I need Internet access to activate my OPC UA Wrapper license?
You do not need Internet access to activate your license. After installing the OPC UA Wrapper, you will have access to the license authorization tool. Using this tool, you will be able generate a User ID code.
Then, you will only have to send us this code so we can generate the activation code for you.
What prerequisites do I need before installing the OPC UA Wrapper?
Prior to installing the OPC UA Wrapper, make sure that you have the following prerequisites available on your target machine:
- OPC core components version 3.00
- .NET framework version 4.0 or higher
- OPC UA Discovery Server service
- Visual C++ Redistributable (x86 and x64).
Where should I install the OPC UA Wrapper?
When using the wrapper features, it is recommended to install the OPC UA Wrapper in the same machine as your OPC Classic Server in order to avoid DCOM.
When using the proxy features, it is recommended to install the OPC UA Proxy in the same machine as your OPC Classic Client in order to avoid DCOM.
The OPC UA Proxy generates long tag IDs e.g. unit/main.XXX[ns*2,s*unit/main.XXX]. Is there a way to edit the tag IDs?
The OPC UA Proxy enables users to configure aliases for the tags via CSV files. The alias will define a friendly tag name of your choice and will be mapped to the original tag name e.g. unit/main.XXX[ns*2,s*unit/main.XXX].
