Simatic RTU3000C - New firmware V3.1 extends the possible uses
Wide range of connections and excellent availability
Siemens is offering a new firmware (FW) version 3.1 for the Simatic RTU3000C (Remote Terminal Unit, RTU). This includes extended connection options for Hart sensors, for example for flow or level measurement. The Extension Board Hart/RS485 supports both Modbus RTU and – with FW V3.1 – Hart multidrop protocol. The convenient and secure remote access to Hart or Modbus RTU devices on the extension board Hart/RS485 is provided via Simatic PDM for remote maintenance. The connection of the RTU3000C to a redundant DNP3 master increases availability. "Hart" stands for Highway Addressable Remote Transducer, a standardized communication system for industrial fieldbuses.
