Industrial controls have evolved from the days of hardwired relay logic-based units to sophisticated internet-connected systems. Legacy-based machine controls’ intelligent processes were configured using basic computer logic circuits. These basic computer logic circuits were created by appropriately wiring the relay contacts to perform such low-level control actions. With the advent of digital controls-based on programmable logic controllers (PLC) and computerized ladder logic software, industrial controls can make complex decisions aided by electronic sensors. One improvement made by the digitization of monitoring and processing functions is the method of machines to communicate with each other. Also, with this machine to machine (M2M) communication method, reduction in wiring through cable bundles are achievable using such digital techniques. An Internet of Things (IoT) wireless approach that has aided M2M improvements in industrial controls is Bluetooth (BT) technology.
