OPC UA DRIVEN AUTONOMOU DECISION MAKING IN INDUSTRIAL IOT

—– The creation of autonomous and intelligent devices for manufacturing firms has been made possible by the Industrial Internet of Things and the progress made in machine-to-machine communication. These autonomous machines are able to collect data from various sensing devices and other related machine systems by using communication protocols such as OPC UA. Here we perform machine to machine communication through an Arduino microcontroller. Any board or computer with a full-size USB A host connector can be connected to the Arduino with the help of a USB-A to USB-B cable. The communication takes place over the serial port (USART/UART). Machines can currently send and receive enough data to enable independent decision-making. Existing low-level machine-to-machine communication only involves data processing, and higher-level decision-making processes are limited to a single machine system rather than communications amongst networked machines. The goal of this effort is to employ OPC UA protocols to improve these limitations in machine-to-machine communication. This could mean deciding how to respond to receiving information and directing both horizontally (same level machines) and vertically (higher level machines) connected equipment. Proactive machine-to-machine communication improves factory intelligence in this way.
