Parameters

consumer

The consumer object that will perform the operation.

The value of this parameter cannot be null (Nothing in Visual Basic).

deviceDescriptor

The Sparkplug device descriptor.

The value of this parameter cannot be null (Nothing in Visual Basic).

metricName

The name of the Sparkplug metric.

The value of this parameter cannot be null (Nothing in Visual Basic).

metricData

The Sparkplug metric data.

The value of this parameter cannot be null (Nothing in Visual Basic).

In Sparkplug terms, this method effectively sends the DCMD message to the device.

If there is an error publishing the payload, this method throws OpcLabs.EasySparkplug.OperationModel.SparkplugException.

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.
