Compact, standalone remote terminal units with separate power supply

Designed for the most remote regions and the harshest environmental conditions:
Compact SIMATIC RTUs

Description

The compact RTUs of the SIMATIC RTU3000C series are stand-alone remote terminal units (RTUs) with separate power supply. This enables the most remote measuring points to be monitored – even in locations where no power supply or hard-wired communication infrastructure exists. Thanks to their optimized energy consumption, the compact SIMATIC RTUs require no external power source. They supply themselves either from battery or accumulator with solar panel.

Details

The compact remote terminal units RTU3010C and SIMATIC RTU3030C are designed for stand-alone operation. They are suited in particular for sites without connection to a public power grid. They feature a flexible power supply: They can be operated with up to 2x3 redundant battery modules. Connection to a battery or a 12-24 V DC power source is also possible. The types of power supply can be freely combined. The RTUs operate reliably even under harsh conditions ranging from -40 to +70 °C. With an external protective enclosure, they can even be used in areas prone to flooding (IP68).

The SIMATIC RTU3030C communicates with the control center through an integrated UMTS modem. The SIMATIC RTU3010C does not have its own communication module. To communicate it uses an externally connected industrial router, such as a SCALANCE M. This enables it to be used flexibly anywhere in the world, for example, using the specific cellular network regulations of the particular country.

Each of the RTUs records measured values from connected sensors (e.g. noise level, flow rate, level, temperature or pressure) and transmits these by cellular network to the control center – secured via an OpenVPN tunnel or an encrypted email. The communication parameters are freely adjustable. If defined values drop below a threshold or exceed it, the RTU reports this immediately via text message or email. This enables service personnel to quickly respond to extraordinary events. Due to the support for various protocols (TeleControl Basic, IEC 60870-5-104, DNP3 and SINAUT ST7), the RTUs can be connected flexibly to any SCADA system.

The RTUs can perform data preprocessing to reduce the data volume and to simplify the data evaluation in the control center. A range of program module types are available for this purpose (such as level monitoring of silos, calculation of overfall quantities for rail overflow basins, logic and time functions). Adjustments to the configuration and firmware updates can be carried out from the control center using a standard web browser. This saves on-site service costs. The compact RTUs can be integrated in the management platform for remote networks – SINEMA Remote Connect – via autoconfiguration. This enables VPN connections to be established per mouse-click.
