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 different protocols.

Example how to read data from a S7-1500 with the IOT2050 via S7, Modbus TCP and OPC UA and store the data in a local database on the IOT2050 using node-red

The IOT2050 application was developed to read barcodes and QR-codes by using an external USB scanner, decode the codes and transmit them using MQTT. The following example uses Docker and Node-Red to do so.

Instructions for using the IOT2050 as a LoRaWAN (Long Range Wide Area Nework) gateway with The Things Network as the network server. LoRaWAN Concentrator is realized with an Arduino Shield.

Application example for the IOT2050 to gather weatherdata, connect to LOGO! and S7-1500 via node-red. All gathered data are displayed on a local node-red dashboard

About This application shows two ways to exchange data via a serial port between PC (Windows/Linux) and the IOT2050. In the first example a pure serial transmission is used, while in the second example the communication protocol Modbus RTU is used additionally.
