Overview

This application example shows three different options that enable the IOT2050 user to read data from a S7-PLC using Node-RED. The data exchange between a S7-1500 or a S7-1200 and the IOT2050 is carried out using the following protocols:

• S7 Communication
• Modbus TCP
• OPC UA

In addition to collecting data, the example also shows, how this data can be stored in a SQL database. To avoid the loss of data in case the connection to the database is interrupted, 3600 values are stored in a ring buffer on the IOT and are immediately sent to the database whenever the connection is reestablished.

Used Components

This Example was created using the following Software:

• On Windows:
  • TIA Portal V16 or V17
• On Ubuntu:
  • Firefox Quantum for Ubuntu canonical - 1.0
  • MariaDB
  • Node-Red

The Tests were executed on the following Hardware:

• SIMATIC IOT 2050
• SIMATIC S7-1500

Goal

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

• Use different protocols to read values from a S7-1200 or S7-1500 PLC
• Store data in a SQL database

Installation and configuration

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

• Configuration of the TIA Project
• Setting up of the IOT2050
• Configuration of the Node-Red Flow
