IND360 integration with PROFINET, OPC UA and API

The IND360 Automation Weighing Indicator from Mettler Toledo is a compact, modular, and industrial-grade weighing solution designed for machine integration, process automation, and IIoT applications.

In this video and guide, we explore how IND360 can be seamlessly integrated with:

• Siemens S7-1500 PLC via PROFINET

• Edge devices via OPC UA

• Modern IT/IIoT systems via REST API

This makes IND360 a powerful choice for filling, dosing, tank weighing, and in-motion weighing applications.

⚙️ Demo 1: IND360 with Siemens S7-1500 PLC (PROFINET)

In this demo:

• IND360 communicates with Siemens S7-1500 PLC via PROFINET

• PLC reads:

  • Net weight

  • Gross weight

  • Status bits

• PLC sends commands:

  • Zero scale

  • Tare scale

  • Clear tare

• Data is visualized on Siemens KTP400 HMI

This setup is ideal for machine-level automation.

🌐 Demo 2: IND360 with OPC UA (Edge Device + Node-RED)

In this demo:

• IND360 exposes data via OPC UA

• An Edge device (reComputer) connects as OPC UA client

• Node-RED is used to:

  • Read live weight values

  • Monitor scale status

  • Execute control commands

• A responsive Node-RED Dashboard shows:

  • Net weight

  • Gross weight

  • Tare

  • Control buttons

This architecture is perfect for IIoT, monitoring, and dashboards.

🌐Demo 3: IND360 with REST API

In this demo:

• IND360 is accessed using REST API

• Edge device sends HTTP requests to:

  • Read measurement data

  • Send scale commands

• Node-RED handles:

  • API calls

  • Logic

  • Dashboard visualization

This approach is ideal for IT-centric systems, cloud integration, and web applications.
