Overview

Modbus RTU Server Serial Product Overview

The Modbus RTU Server Serial device driver provides data exchange between OPC clients, Modbus Client, and Modbus RTU networks. The Modbus RTU Server Serial driver allows a OPC client application to appear as 1 to 247 Modbus RTU devices on the network. The server mode allows Kepware to receive data by exception from a Modbus RTU Client. Typical applications include connectivity with larger DCS systems that utilize Modbus RTU. As with any server device, the Modbus RTU Server driver will only transfer data when being read or written by a RTU client. Data integrity is ensured with our extensive error handling.
