This webinar is a beginner-friendly introduction to data acquisition (DAQ) designed for non-engineers, explaining how real-world signals like temperature or machine status are converted into digital data that computers and controllers can read, display, and log. The presenter breaks down the core building blocks of a DAQ system—sensors, analog vs. digital signal types, I/O modules, wiring (RS-485 vs. Ethernet), and communication protocols like Modbus RTU and Modbus TCP—then shows how to select the right hardware for a simple application. The video walks through a practical example using a Modbus RTU remote I/O module, a USB-to-RS-485 converter, and DCON Utility to find and configure the module, then explains how a standard Windows PC can be used as a data logger with EZ Data Logger (and when to step up to more advanced tools like eLogger or SCADA software for larger systems).
