Telecontrol unit with integrated GPS functionality for new use cases

The compact and robust Simatic RTU3000C telecontrol units are specially designed for energy-autonomous operation in environments without a power supply system and optimized for low-power operation. 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 new device not only supports connection to a control center with telecontrol protocols (IEC 60870, DNP3, Sinaut ST7, and TeleControl Basic), but 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 high-speed solid-state relays alongside the standard four analog inputs (AI), digital inputs (DI) and four DQ.
The new 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. This benefits users from a wide range of different industries who want to take advantage of additional information from the sensors (e.g. diagnostic information).
The new 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 new 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 faster connection establishment for encrypted connections.
