Ethernet Modbus Gateway

The Ethernet Gateway Modbus – ZigBee ZC-GW-ETH-xx is part of an assortment of 4noks ZigBee devices. The purpose for which it was created is to interface a PLC (Programmable Logic Control) or a PC with the 4-noks ZigBee devices network through an Ethernet network and a standard protocol universally recognized such the Modbus/TCP-IP.

The employment of an Ethernet network allows to locate the Personal Computer or the PLC in a position very far from the ZigBee network and, if you have an Internet access, into an even farther position.

The gateway, for what concerns the ZigBee network, is one of the available coordinating type devices. This means that it has an active function in the network creation and in keeping the radio traffic between the ZigBee network devices. Moreover, they can work as “father” devices for battery powered sensors and can memorize the information that they asynchronously transmit compared with the ModBus interrogations.
Along with the ZR-BR-485-EM device, this gateway offers a transparent Modbus channel. The version coded ZC-GW-ETH-EPM is powered through the 48Vcc present on the Ethernet cable connectors (POE power supply), while the version with code ZC-GW-ETH-EM is powered by a 12Vcc external source.
