The philosophy behind the Kingfisher RTU design is delivery of a product to the world market that is extremely configurable and expandable, thus ensuring that our customers have an exact solution to their immediate remote monitoring and control requirements that could also grow with changing needs. RTUnet has successfully turned this concept into an affordable product in the form of the Kingfisher range of RTUs.

The Kingfisher Series II Remote Terminal Unit design allows the user to create custom solutions by plugging a wide range of modules onto a backplane. This flexibility allows RTUs to be constructed to meet the exact needs of each site.

Each RTU can have as few as four I/O and one communication port to thousands of I/O and sixteen communication ports.

Once your requirements are established, simply customise a Kingfisher Series II RTU to meet your needs. Should your requirements grow in the future, just upgrade your existing RTU by plugging in new modules or downloading new firmware. Now that’s true flexibility and future proofing!

Flexibility to create the perfect RTU solution
Kingfisher Series II’s individual modules can be assembled in almost any configuration to achieve the best solution.

• 4 to >1000 I/O
• 1 to 16 communication ports
• Backplanes may be daisy chained to expand I/O and communication ports capacity
• Multi I/O modules combine analog and digital I/Os (eg. 2xAI, 8xDI, 2xDO) in one module.

Easy upgrade path
The modular design of Kingfisher Series II RTUs allows its capacity to be expanded by plugging in new modules and its capabilities increased by downloading new firmware and software.

Connects to a range of communication equipment
Kingfisher RTUs can connect to a wide range of media that include:

• dedicated radio
• packet radio
• satellite
• PSTN dial-up
• GSM
• CDMA
• GPRS
• two-wire and four-wire leased lines
• RS232/RS485/RS422
• Ethernet
• fibre optic

Kingfisher RTUs can also initiate alphanumeric messages to pager receivers and mobile phones (SMS).

Processing power
Powerful Intel processors, large memory capacity and a real-time operating system provide the power for quick logic processing, communications and data storage. Kingfisher RTUs provide control capabilities that were previously only available in PLCs.

Compatible with many devices and networks
Kingfisher Series II RTUs communicate using a wide range of protocols that provide connection to local devices such as PLCs, flow computers, shaft encoders, smart transducers, circuit breakers and pager radios. Connection to communication networks is also provided, including support of the Hayes AT command set, DNP3 protocol, MODBUS protocol, TCP/IP and emulation of other RTU and PLC manufacturers’ protocols.

Easy configuration
Toolbox, a Microsoft Windows based RTU configuration and diagnostic program offers on-line help, configuration examples, and drag and drop capabilities. Toolbox features IEC 61131-3 compliant editing and allows you to configure RTUs remotely or locally, on-line or off-line, and from RTU to RTU, or PC to RTU. Control is implemented using ladder logic which is compiled and downloaded into the RTU. The use of databases for definition of I/O and system variables allows the importing and exporting of configuration data to and from other SCADA system databases.

Advanced power management features
Power consumption can be reduced by up to 90%. Kingfisher RTUs can shut down field power between scans and maintain a low power idle state until woken by an event.

RTU self-configuration
The Series II RTU auto-detects the presence of modules plugged in the backplane(s), and will generate alarms if a module fails or is inserted in the wrong location. Modules can be 'hot swapped' or added while the RTU is running.

Plug it in and go!
Kingfisher RTUs are designed to plug in and go to work for you with a minimum of fuss. Our systems engineering experts can also assist with a packaged or boxed solution which is customised to your particular site, application and communication requirements.
