R-KEY-LT, Z-KEY, and Z-KEY-2ETH extend networks and allow process data to pass between different IT and industrial communication architecture layers. Modbus RTU to Modbus TCP/IP gateways are essential components in industrial automation and communication systems. They function as intermediaries between the Modbus RTU and Modbus TCP/IP communication protocols, facilitating seamless data exchange.
In the realm of communication protocols, Modbus RTU is a widely adopted serial standard, while Modbus TCP/IP represents the modern Ethernet-based counterpart tailored for contemporary network infrastructures. These gateways play a critical role by enabling the smooth transition of data between Modbus RTU devices and TCP/IP networks. Their significance lies in their capacity to:
Modbus RTU to Modbus TCP/IP gateways occupy a pivotal role in bridging the gap between Modbus communication protocols in industrial settings. Their ability to facilitate communication, extend equipment compatibility, and enhance network capabilities makes them indispensable components within the ever-evolving landscape of industrial automation and data exchange.
