The application describes how data can be stored, structured and read out on a local OPC UA server built with Node-Red. The data used are read out from an S7 PLC using the following protocols:

• S7 Communication
• Modbus TCP
• OPC UA

This Example was created using the following Software:

• On Windows:
  • TIA Portal V16 or V17
  • S7-PLCSIM Advanced V3.0
  • optional: UaExpert V1.5.1
• On Debian (IOT2050):
  • Node-Red

The Tests were executed on the following Hardware:

• SIMATIC IOT2050
• SIMATIC S7-1500 (simulated)

After working through the following documents, you will know how to:

• Use different protocols to read values from a S7-1500 PLC
• Build a OPC UA Server on the IOT2050 with Node-Red
• Store the transferred values on the OPC UA Server
• Read the values from the OPC UA Server via Node-Red and UaExpert

Use the following documents for the configuration of the IOT2050 and S7-1500:

• Setting up of the simulated S7-PLC
• Configuration of the TIA Project
• Setting up of the IOT2050 & Configuration of the Node-Red Flow
