Introduction
In .NET Core and .NET 5.0+, some internal parameters of OPC XML-DA communication are configurable using High-Level Intrinsic Configuration mechanism.
Under the OpcXml.Da10.Service.BasicHttpBinding key, you can configure parameters used for HTTP communication. Available for configuration are properties of the BasicHttpBinding class and its base classes, i.e.:
Note that some of the configured binding properties can get overriden by the code. Specifically, settings under BasicHttpBinding.Security are overriden if a network credential with non-empty user name is provided for OPC XML-DA communication.
Example
In order to set extremely high limits for the size of received OPC XML-DA messages, you can use the following appsettings.json file:
{
"OpcXml.Da10.Service": {
"BasicHttpBinding": {
"MaxBufferSize": 2147483647,
"MaxReceivedMessageSize": 2147483647
}
}
}
