Kepware's Modbus Unsolicited Serial device driver works in conjunction with our OPC Server KEPServerEX, to provide data exchange between OPC Clients, Modbus Masters and a Modbus RTU networks. The Modbus Unsolicited Serial (Slave) driver allows a OPC client application to appear as 1 to 247 Modbus RTU devices on the network. The slave mode allows the server to receive data by exception from a Modbus RTU master. Typical applications include connectivity with larger DCS systems that utilize Modbus RTU. As with any slave device, the Modbus RTU Slave driver will only transfer data when being read or written by a RTU master. Data integrity is ensured with our extensive error handling.
