Key features
|
The Gateway Modbus USB is part of the family of Digitron wireless ZigBee devices. Its purpose is to be an interface between a Personal Computer and the network of Digitron ZigBee devices using an universal standard protocol such as Modbus/RTU via USB port. The use of Modbus protocol guarantees an immediate use of many commercials Scada for PC.
The device is supplied directly from the USB port; its role in the ZigBee network is Coordinator, i.e. it forms an active part in creating the network and maintaining wireless traffi c from and to other similar devices. Furthermore it can function as parent device for battery sensors of the same family and saves data that they asynchronously send regardless of Modbus requests.
