Gateway Modbus RS485

4-noks

The RS485 Modbus Gateway – ZigBee ZC-GW-485-EM is part of an assortment of 4-noks 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 a RS485 serial interface and a standard protocol universally recognized such the Modbus/RTU.
