The logged data is typically saved in (Comma Separated Values) format, which can be opened directly in Microsoft Excel, Google Sheets, or any data analysis tool.

In the rapidly evolving landscape of industrial automation, data is the new currency. From predictive maintenance to quality control, the ability to capture, store, and analyze process variables is no longer a luxury—it is a necessity. For engineers and integrators working within the Delta Electronics ecosystem, leveraging the capabilities of a Human Machine Interface (HMI) for this purpose is a game-changer.

At its core, data logging in a Delta HMI involves capturing real-time information from a connected controller, such as a Delta PLC , and storing it in a digital format for later analysis.

Newer Delta HMIs support FTP (File Transfer Protocol) and SMTP (Email). The HMI can log data to a file and automatically push that file to a server or send an email with the log attached.

Create buttons on the HMI screen to manually trigger a "Save to USB" or to safely "Remove USB" to prevent file corruption. Simulation:
