DigiGate Profibus - Gateway Profibus DP / Modbus RTU
The Novus DigiGate Profibus is a small, highly durable device that is ideal for interconnecting a Profibus DP network with a Modbus RTU network. It works as a gateway, operating as a master station in the Modbus network and as a slave station in the Profibus network. Thus, according to its previous configuration, DigiGate will read the data of the other devices (slaves) of the Modbus network and send the read values to the Profibus master. In the same way, it will write at the output of the Modbus slaves according to the Profibus master requests, providing a complete control of the Modbus network devices through the Profibus network. The device is totally configurable through the DigiConfig Software for Windows®, which comes with the product, making access and change of its parameters very easy.
