OPCUA.RESPOND

This is a premium feature.

Sends a response directly, i.e. without any Consumer, to an OPC UA service. The data to be send can be either arbitrary JSON data or a message from the outbox or inbox. Usually this function is used to respond to a previously received request-message.

info

A request-message must provide a requestId property within its Metadata object.

Syntax

=OPCUA.RESPOND(requestId, MessageOrJSON)

Arguments

Name	Description
requestId	The requestId as provided by a previously received request-message
MessageOrJSON	Data to send as response.

Return

Color switch to blue on success. Otherwise to red with an error code.

Examples

We assume that a request-message was received and that it provides a requestId which we store to cell B1 by using the read function as follows: READ(INBOXMETADATA(,,"requestId"), B1, "String")

Formula	Result	Comment
=OPCUA.RESPOND(B1,OUTBOX("Message"))	TRUE	Sends the message with id Message from the outbox to an OPCUA Service using the requestId in B1
=OPCUA.RESPOND(B1,DICTIONARY(A3:C5))	TRUE	Sends the JSON data provided by the Dictionary function to an OPCUA Service using the requestId in B1
