Workflow Setup

Creating an FTP connection

Unlike SFTP, the FTP node is not created as a component. It will only establish a connection at the time of the workflow—when the iteration reaches that point. Therefore, no component needs to be created.

To use FTP, the following steps must be performed.

1. In the context menu, look for the “Upload (FTP)” node - there is a separate node for CSV applications.

2. Now fill the Upload (FTP) node with the connection parameters.

3. Attach the data you want to transmit – in this example, an image – to the payload.

Congratulations! You can now upload data to the FTP server.

4. The filename can be generated dynamically in the next step, for example using “Append” and the current time. This way, the file 20250731_145234_cam1.jpg will be saved in Directory1/Directory2.

5. Folders and filenames can also be defined dynamically depending on the result. In the example, the “Result” controls not only the folder but also the input for the filename.

Result = iO: Stored in directory iO with filename 20250731_145234_cam2_iO.jpg
Result = niO: Stored in directory niO with filename 20250731_145234_cam2_niO.jpg

Congratulations! You can now dynamically adjust filenames and store them in different folders depending on the situation.

6. Via the “Success” and “Message” outputs, you can retrieve information about each iteration of the data transmission process.

Creating an SFTP Connection

This type of FTP transfer is usually preferred by most customers.

1. In the workflow's context menu, also search for and select the "Upload (SFTP)" node.

2. Now fill the upload (SFTP) node with the connection parameters.

3. You can then embed the node in your workflow, similar to how you would with FTP (FTP/SFTP | Anlegen-einer-FTP-Verbindung).

Congratulations! You can now also use the SFTP node dynamically.

Upload File (FTP)

Instead of a byte array, you can also directly access files from the camera's file system and upload them.

Sends an FTP datagram to a remote host. The File Transfer Protocol (FTP) is a standard network protocol for transferring files between computers on a network.

Important:

Direct access to an FTP server from a production network may not be possible immediately, as this requires special access rights that need to be configured by your system administrator.

Upload File (SFTP)

Instead of a byte array, you can also directly access files from the camera's file system and upload them.

Sends an SFTP datagram to a remote host. Secure File Transfer Protocol (SFTP) is a standard network protocol for secure, encrypted file transfer between computers.

Important:

This node requires an SFTP instance. You can create a "Send SFTP" node in the component area and add it to the workflow via "Retrieve Node".
