The Simatic RTU3030C RTU works fully independently with a power supply provided by batteries or a solar panel, enabling its flexible use in varied fields of application such as the water and wastewater industry.

The RTU’s robust design enables it to be used under the toughest of ambient conditions (-40 to +70°C). An additional enclosure with a protection rating of IP68 allows reliable operation even under flood conditions. It can be operated using up to two high-powered industrial batteries or a rechargeable battery (combinable with a solar panel). Users also have the option of connecting a 12–24 VDC power source where this is available.

The RTU3030C can be operated in sleep, update, communication and service modes. The power requirement in the sleep mode is less than 2 mW, allowing operation over a period of several years. Connection to the control centre uses the integrated UMTS modem over the wireless network — with a secured OpenVPN connection or encrypted emails. Communication can be time or event controlled and also individually configured for each process value. Service mode is used for maintenance operations such as exchanging batteries without loss of data.

The Simatic RTU3030C can be linked to a Simatic PCS 7 control system or to Simatic WinCC using the TeleControl Server Basic software package. Direct connection to Simatic PCS 7 TeleControl or Simatic WinCC/TeleControl is also possible using the telecontrol protocols IEC 60870-5-104 and DNP3. In this way, support for wide-ranging telecontrol protocols enables flexible connection to any optional SCADA system.
