In this chapter, we will simulate a very simple industrial data flow to implement data acquisition through a simple edge device. To simulate the industrial data flow, we will use an OPC UA Simulation Server to generate the signals. OPC UA is managed by the OPC Foundation (https://opcfoundation.org/) and is the most common industrial operability standard. Several vendors have implemented their own solutions according to the OPC UA standard. We can find other open source drivers for the most common languages, such as Node.js, Python, and Java.
