Key features
|
Gateway Modbus RS485 is part of the family of Digitron wireless ZigBee devices. Its purpose is to be an interface between a PLC (Programmable Logic Control) or a Personal Computer and the network of Digitron ZigBee devices using an universal standard protocol such as Modbus/RTU via RS485 serial interface. The use of Modbus protocol guarantees an immediate use of all commercial PLC and many Scada for PC.
Its role in the ZigBee network is Coordinator, i.e. it forms an active part of creating the network and maintaining wireless traffi c from and to other similar devices. Furthermore it can function as parent device for battery powered sensors of the same family and saves data that they asynchronously send regardless of Modbus requests.
