One of the most salient features of HUSKY RTU is its wide repository of communication protocols. Industry standard protocols like IEC 60870-5-101, 104, DNP 3.0 are provided in both client/server configurations. Further protocols like IEC 60870-5-103, IEC 61850-8-1 are available for interfacing with IEDs.
Communications can be for either acquisition of data from subordinate devices or transfer of information to a higher level system like SCADA. Further, peer-to-peer or horizontal communications can be performed by the RTU in case of multi-node architectures. Both serial and Ethernet interfaces are available on the processor module itself. Additional interfaces can be added to the RTU through communication extender modules (CXMs).
With support for multiple masters with partitioned database and support for redundant communication links, connectivity is assured. Multiple protocols can be configured on the CPU ports itself thereby eliminating the requirement of separate communication modules. The RTU can be configured to act as protocol converter or data concentrator. It can collect data from subordinate devices and transmit to master stations on any of the supported protocols. This allows the RTU to collect data from IEDs like Energy Meters, Numerical Relays, Disturbance Recorders, Governor Controllers, Flow computers, Gas Chromatographs and Station Controllers. RTU 6049-E70 can provide a simplified solution by providing out-of-the-box connectivity solution. It can be used as a Bay Controller, Unit Controller or Station Controller depending upon the process requirements.
RTU 6049-E70 supports traditional copper-based interfaces like RS232, RS485, 10/100-baseT Ethernet. Fibre-optic based Ethernet interface are also available on select CXM modules. The RTU can also interface with PSTN leased-line or dial-up modems using RS232 ports. Similarly, GSM/GPRS/CDMA/HSPA modems can be interfaced over RS232 ports for providing wireless connectivity to the RTU.
The RTU can also provide a transparent Ethernet to serial pass-through channel between a master station connected over TCP/IP and a subordinate device connected to the RTU over an RS232/RS485 port. This feature can be used by an operator at the master station to remotely manage the device without requiring a direct physical connection to the device.
