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.
Tag From Node Documentation
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.
Node Overview
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.
Node Interaction
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. The Tag From node will receive these variables and make them available for use in subsequent nodes.
Input and Output Sockets
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.
Implementation Details
The Tag From node follows these steps to receive variables:
1.Variable Reception: The Tag From node waits for variables sent by the corresponding Tag 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.
Usage
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 node.
4.Connect the output socket of the 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. The Tag From node will receive these variables and make them available for use in subsequent nodes.
Notes
The Tag From node allows you to receive variables sent by the Tag 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.
