Industrial Use of Bluetooth
Industrial plants consist of many devices interconnected in different ways. It might be simple data collection units (I/Os) without any built-in intelligence, more intelligent devices (for example sensors with built-in intelligence, single-loop controllers, or programmable controllers) and supervisory systems (used as HMI, for data logging and supervisory control). These types of devices are interconnected using many different communication protocols and medias, which may in some cases be replaced with Bluetooth wireless technology. This technical paper discusses how Bluetooth may be used to connect these devices with each other. It also describes some specific requirements on the Bluetooth technology within this area.
