OPC UA Server
System manual
2696790000/02/04.2020
60
Designation Description
ShowVariableTree Display of generic variable tree (1 = activated, 0 = deactivated)
Example
[OpcUa]
[OpcUa.Application]
Port=4840
ApplicationName="SampleApplicationName"
ApplicationURI="SampleApplicationURI"
ProductURI="http://www.company.com/"
ProductName="OPC-UA Server"
Manufacturer Name="Sample Manufacturer"
ShowVariableTree = 1 // 1 = activate, 0 = deactivate
"SecureChannel"configurations
With an encrypted connection, the Basic256Sha256 encryption algorithm is
supported with 2 different setting options (Sign and Sign and Encrypt). All
configuration values can be configured via integer values.
Security Policy Value
Basic256Sha256 3
Message Mode Value
Sign 1
Sign and Encrypt 2
Information
The "Basic256" and "Basic128Rsa15" encryption algorithms are no longer
supported because they no longer meet current security requirements.
Example (default setting)
[OpcUa]
// Policy 3 = Basic256Sha256
// MessageMode 1 = Sign, 2 = SignAndEncrypt
[OpcUa.Security.CommunicationChannel.Communication:0]
Policy=3
MessageMode=1
[OpcUa.Security.CommunicationChannel.Communication:1]
Policy=3
MessageMode=2
Additional communication channels (CommunicationChannel) with different
security settings can be added. Each additional connection is declared with
an ascending number. The number must be unique. The Policy and Mes-
sageMode entries must always be set for each connection.
"Subscription" configuration
For the "Subscription" service, the supported time intervals can be config-
ured. By default, 50 ms is set for the minimum and 3 600 000 ms for the
maximum limit.
