Tag From
This block is used to assign data to a variable name in the programming interface, rather than making a socket-to-socket connection. The data assigned with the tag to block can be used. Especially in complex programming, it makes the program simpler and more understandable.
In AugeLab Studio, the flow is from left to right, and with these blocks you cannot link the result data of a transaction to a previous block. This process is called feedback and the program throws an error. To do this, you can use Data Store Read and Write blocks in the Function Blocks - Inputs section.

The
Tag From
node in AugeLab Studio is used to receive variables sent by the Tag To
node. It acts as a receiver and allows the flow of variables between different parts of a data pipeline.The
Tag From
node is used to receive variables sent by the Tag To
node. It acts as a receiver or listener for variables with a specific tag. The Tag From
node receives the variables and makes them available for use in subsequent nodes in the data pipeline.- 1.Drag and drop the
Tag From
node from the node library onto the canvas in AugeLab Studio. - 2.Double-click on the
Tag From
node to open the node properties panel. - 3.Enter a unique tag name in the text field provided. This tag name will be used to identify the variables sent by the corresponding
Tag To
node. - 4.Connect the output socket of the
Tag From
node to other nodes in your workflow to use the received variables. - 5.In other parts of the data pipeline, use the
Tag To
node to send variables with the same tag name. TheTag From
node will receive these variables and make them available for use in subsequent nodes.
- Input Sockets:
- The
Tag From
node does not have any input sockets.
- Output Sockets:
- The
Tag From
node has a single output socket of type "Generic". This socket is used to pass the received variables to other nodes in the workflow.
The
Tag From
node follows these steps to receive variables:- 1.Variable Reception: The
Tag From
node waits for variables sent by the correspondingTag To
node with the same tag name. - 2.Variable Availability: Once a variable is received, it becomes available at the output socket of the
Tag From
node. - 3.Variable Usage: The received variable can be accessed and used by connecting the output socket of the
Tag From
node to other nodes in the data pipeline.
The
Tag From
node ensures that only one Tag To
node can send variables with the same tag name to avoid conflicts.- 1.Drag and drop the
Tag From
node from the node library onto the canvas in AugeLab Studio. - 2.Double-click on the
Tag From
node to open the node properties panel. - 3.Enter a unique tag name in the text field. This tag name will be used to identify the variables sent by the corresponding
Tag To

Tag From
node to other nodes in your workflow to use the received variables. - 5.Use the
Tag To
node in other parts of the data pipeline to send variables with the same tag name. TheTag From
node will receive these variables and make them available for use in subsequent nodes.
- The
Tag From
node allows you to receive variables sent by theTag To
node with the same tag name. - The tag name specified in the
Tag From
node should be unique within the data pipeline to avoid conflicts. - The
Tag From
node can be used to create dynamic and flexible data pipelines where variables can be sent and received between different parts of the workflow. - The
Tag From
node enhances the capabilities of AugeLab Studio for creating complex data processing pipelines that involve communication between different nodes. - It provides a way to decouple the data flow and enables communication between nodes that are not directly connected.
- The
Tag From
node is a powerful tool for creating custom data processing and transformation workflows in AugeLab Studio.
