Siemens releases Simatic RTU3031C (Remote Terminal Unit/RTU) with integrated GPS functionality

July 5, 2018 - Siemens introduced the Simatic RTU3031C (Remote Terminal Unit/RTU) with integrated GPS functionality for comparing the setpoint with the actual position. That makes it suitable for static applications such as the monitoring of distributed measuring points in the water industry, and also for mobile applications that require localization functions. This includes, for example, position monitoring for floating navigation signs or container tracking. In addition, Siemens is introducing an extension board that allows users to connect up to eight additional sensors to the telecontrol units. Firmware for the product family also offers users functions, such as connection to redundant control centers and function blocks for the statistical evaluation of process values.

The Simatic RTU3000C telecontrol units are specially designed for energy-autonomous operation in environments without a power supply system. They can be supplied with power redundantly, for example with up to six battery modules or rechargeable battery with solar panel. They can also be used under harsh ambient conditions such as temperatures from -40 °C to +70 °C or in flooding (with external IP68 protective enclosure).. With the Simatic RTU3031C, Siemens is expanding this product family with an RTU that can be connected to a GPS antenna and that provides localization and time synchronization functions via the GPS signal. Users can thus monitor process data such as fill level, level and flow as well as pressure and temperature at remote and even mobile measuring points.

The RTU3031C features an integrated UMTS modem, with which the collected data is sent to a control center in a time or event- oriented manner. Like all telecontrol units in the RTU3000C product family, the device supports connection to a control center with telecontrol protocols (IEC 60870, DNP3, Sinaut ST7, and TeleControl Basic), and also use as a data logger. In addition, all measured process values can be stored in internal memory or on an SD card and, if required, read out remotely via web-based management or sent to defined partners via secure file transfer or e-mail. Integrated inputs and outputs allow the sensors to be connected directly. The device is the only one in the family that offers four additional digital outputs (DQ) designed as solid-state relays alongside the standard four analog inputs (AI), digital inputs (DI) and four DQ.

The extension board for the RTU3000C product family enables the connection of eight additional sensors via Modbus RTU. It can be used with all variants in the product family, such as with the Sitrans FM MAG8000 for flow measurements.

The V3 firmware provides numerous improvements, such as connection to control centers with redundant IEC 60870 masters, extensions in web-based management and user administration, WAN connection via DNP3, and IEC 60870 without OpenVPN to operate the RTU3030C or RTU3031C over connections that are already encrypted by mobile telephony providers (private APNs). Additionally, users have access to function blocks for statistical functions, pulse train output for precise control of periodic signals, and module operating state management (e.g. safe shutdown, restart, etc.). This also allows connection establishment for encrypted connections.
