Software-specific information • OPC UA server • Information model
6.7 OPC UA server
The Power Panel can be configured as an OPC UA server (see "Service page OPC UA" on page 70). The OPC UA server of the Power Panel provides the following functionalities:
•Configuration of the Power Panel as is also possible via the "service pages" on page 44.
•Reading status information (temperature, version information, etc.).
•Querying the touch screen keys.
•Calling up functions/methods (setting brightness, triggering signal tone, etc.)
Important!
The OPC UA server is stopped while the Power Panel service page is active.
General information about OPC UA
Corresponding knowledge of "OPC Unified Architecture" (OPC UA) is required to communicate with the OPC UA server of the Power Panel. Corresponding information is available on the OPC Foundation website, for example (→ opcfoundation.org).
Communication via library AsOpcUac
Using library AsOpcUac, an OPC UA client can be created on B&R systems that communicates with the OPC UA server of the Power Panel.
The function blocks contained in the library for OPC UA client functionality were developed in a collaboration between working groups of the OPC Foundation and PLCopen.
Information:
Additional information about OPC UA and programming with library AsOpcUac is available in Automation Help.
Graphical OPC UA clients
During development, it is helpful to use a graphical OPC UA client to determine attributes and node IDs of nodes and methods.
The OPC UA client UaExpert from Unified Automation GmbH (→ www.unified-automation.com) is very popular.
6.7.1 Information model
General information
In addition to the basic model of the OPC UA specification and the OPC UA Companion specification for device integration (DI = Device Integration), the OPC UA information model of the Power Panel provides both properties and methods for configuring and operating the Power Panel in its own address space (namespace).
6.7.1.1 Namespaces
Namespaces are used by OPC UA to create unique identifiers. Attributes NodeId and BrowseName are identifiers that identify a node within the entire information model. A node in the OPC UA address space is uniquely identified with attribute NodeId. Attribute BrowseName alone cannot be used to uniquely identify a node. Different nodes can use the same BrowseName. BrowseNames can be combined to a path (Browse path) with which a certain node can be localized in the OPC UA address space and attribute NodeId can be determined.
The node identifiers are partly specified in the OPC UA specification or by B&R. A namespace therefore specifies which institution defined the node (naming authority) and is listed in the form of a namespace URI.

Power Panel T50 User's manual V1.22 - Translation of the original documentation |
Software-specific information • OPC UA server • Information model
The following namespaces are used in the OPC UA server of the Power Panel:
ns |
Namespace URI |
Description |
|
0 |
http://opcfoundation.org/UA/ |
Address space for types and objects defined in the OPC UA specification. |
|
|
|
Namespace index |
0 |
1 |
urn:[hostname]/BR/UA/EmbeddedServer |
This namespace URI represents the address space of the device on which the OPC UA server is |
|
|
|
running. |
|
|
|
[hostname] |
Hostname of the OPC UA server. This corresponds to the hostname spec- |
|
|
|
ified in the network settings of the device. |
|
|
|
If no hostname was specified in the network settings, the name "PPT50" is |
|
|
|
used automatically. |
|
|
Namespace index |
1 |
2 |
http://opcfoundation.org/UA/DI/ |
Address space for types |
and objects defined in the OPC UA Companion specification for device |
|
|
integration (DI = Device Integration). |
|
3 |
http://br-automation.com/OpcUa/BrTypes/ |
Address space for general types and objects defined by B&R. |
|
4 |
http://br-automation.com/OpcUa/HMI/Terminal/ |
Address space for types and objects of the device defined by B&R. |
|
ns |
Namespace index |
|
|
Information:
Namespace URIs are case-sensitive and must be taken into account.
Only the namespace indices 0 and 1 are defined according to the OPC UA specification. The other namespace indices in this documentation may differ from the indices generated on the device.
The recommended procedure here is to dynamically determine the namespace indexes and use a namespace cache.
Important!
Attribute NodeId of each node can change with a new version of the PPT image.
Explicit (fixed) use of NodeIds leads to problems in this case. NodeIds should therefore always be determined dynamically and managed in a node cache during communication with the OPC UA server.
Syntax for namespaces and nodes
This documentation describes a node in the information model using the namespace and BrowseName. The following syntax is used for this:
Path:
ns:BrowseName
ns |
Namespace index of the node. |
BrowseName |
BrowseName of the node. |
A complete path to a node would look like this:
Path:
0:Root/0:Objects/2:DeviceSet/4:PowerPanel T50 /3:Configuration/4:Startup/4:StartMode
6.7.1.2 Symbols for object types
Depending on the object type of the nodes of the information model, the following symbols are used in some places:
Symbol |
Object type |
Note |

|
|
|
BaseObject |

|
|

Contains additional objects/nodes. |
|
|
|
|
Method |
These nodes provide methods for executing functions on the device. |
|
|
|
|
Variable |
These nodes provide variables/parameters for configuring the device or for reading information from the device. |
|
|
|
|
Variable |
These nodes provide variables/parameters for reading information from the device. |
|
|
|
|
Property |
Device-specific properties of the device are read out via these nodes in order to be able to identify the device. |
