OPCUA-IIoT-Method-Caller

OPC UA IIoT Method Caller

The Node is to call a basic or complex method on the OPC UA server.

Input

If the settings of the node are filled, then a simple inject will work, otherwise the incoming has to receive a complex message with all parameters.

You need to add your XML definition of types and attributes to the server.

Simple event message payload could be a simple inject if the node parameters are filled or you have to send the parameters via msg object like:

msg.payload.

• objectId (Object-Id)

• methodId (Method-Id)

• inputArguments (Array)

• • name (just to name the method parameter - has no effect to later use for now)
  • dataType (all node-opcua DataTypes)
  • value (value or Variant as expected from node-opcua)
• methodType (basic, complex)

The settings in that node will override incoming data if the msg property is empty or undefined.

Complex event message:

• objectId (Object-Id)

• methodId (Method-Id)

• inputArguments (Array)

• • dataType
  • value

• methodType

• nodetype

Output

• payload (Array)

• • statusCode
  • inputArgumentResults (Array)
  • inputArgumentDiagnosticInfos (Array)
  • outputArguments (Array)

• definitionResults

• • methodId
  • methodDefinition
