Information
Base class for requests (read or write) that operates on a list of nodes.
Nodes are added to the list by connecting the corresponding Read or Write component to the list_b connector.
The request is performed on every clock tick using the client connected to parentID.
The clock can either be provided externally using the clock input or inferred from the connected components by setting inferredClock to true.
Each OPC UA request returns a status code, the severity of the status code is reported on the severity output and error handling is configured with the errorHandling parameter.
