Modbus TCP/Ethernet to High Powered Wireless System Gateway in Wall Mounting Enclosure with Antenna, 12/24Vdc Supply (External Plug-Top PSU Included)

The 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 areas 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 traffic 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 48 Vdc on the Ethernet cable (POE), whereas the part number ZC-GW-ETH EM is supplied by external supply (12 Vdc).
