Gateway ModBus Ethernet - ZigBee
 |
Gateway Modbus Ethernet is part of the family of 4-noks wireless ZigBee devices. Its purpose is to be an interface between a Personal Computer or an advanced PLC with the network of 4-noks devices using an universal standard protocol such as Modbus/TCP-IP and trough Ethernet network.

The use of an Ethernet network allows to position the Personal Computer or the PLC in places that are far from the ZigBee network or in very remote places if an internet connection is available. 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. In conjunction with the bridge ZR-BR-EM, this gateway offers a transparent Modbus channel. The device with the part number ZC-GW-ETH-EPM is supplied by 48Vdc on the Ethernet cable (Power over Ethernet), whereas the part number ZC-GW-ETH EM is supplied by external supply (12Vdc).
