User-friendly remote access
With firmware version V3.1 for compact Simatic RTU3000C remote terminal units, Simatic PDM can be used. PDM (Process Device Manager) is a manufacturer-independant tool for project engineering, configuration, diagnostics and maintenance of intelligent sensors and field devices. They are connected to the optional extension board Hart/RS485 via Modbus RTU or Hart multidrop and thus connected directly to the RTU3000C. This enables user-friendly remote access to connected Modbus RTU or Hart sensors for remote maintenance applications. The process data acquired by the outstation is timestamped and transmitted to the control center via remote control protocols such as DNP3, IEC 60870-5-104, Sinaut ST7 or TeleControl Server Basic. Reading is of course also possible via the remote connection.
