While sensors have a lot to say, gateways must have really big ears
Collection of data from sensors, and communication of instructions to actuators, is performed by gateways. Whenever so assigned by the Analytics & Decision layer, gateways also perform distributed decisions.
Gateways designed for IIoT must fulfil a number of very important criteria which general purpose gateways do not.
Free2move's Celebes gateways in the 2Connect™ family are designed to meet these important criteria. The Celebes makes use of a low overhead proprietary protocol to communicate to other 2Connect™ devices. It also supports Bluetooth Smart and a number of other standards for communication with legacy networks.
In resilient automation it is important to have the decisions made as close to the actuators as possible. For this reason, 2Connect™ distributes decision logic from the analytics and decision layer to the data collection layer. Free2move’s gateways are equipped with powerful and reliable processing units.
Another important requirement on an industrial IoT gateway is to offload devices as much as possible. IoT devices, such as sensors, are often ultra-low power designs powered by batteries. The gateway has the important task of simplifying data reporting for the sensors as much as feasible, and translate these as much as possible for the analytics and decision layer.
