HUSKY RTU

6049-E70

HUSKY RTU 6049-E70 has been designed to address data acquisition and control requirements of various industry segments. The RTU follows a scalable architecture that’s expandable while maintaining flexibility and adaptability to suit different application scenarios.

The RTU is designed for mounting in 4U-high sub-racks. Choice of I/O modules with varying densities, and chassis backplanes are available for optimal configuration of different application needs. The RTU can be configured to suit I/O requirements of medium to high range applications, through addition of I/O modules and expansion racks. All racks have generic I/O slots, which can be used for any of the supported I/O modules. This architecture aids in flexibility of system design while keeping costs to the optimum.

I/O Architecture

All I/O modules are designed with an onboard dedicated 32-bit microcontroller. This aids in faster I/O scanning and maintaining of time-stamps as close to the field interface as possible. Further, I/O module specific intelligence is offloaded by the CPU to these microcontrollers, thereby alleviating the load on the main processor.

While interfacing with field signals, all I/O modules provide a minimum of 1kV isolation between the field and the internal logic. Further, all field signals that enter the I/O modules are protected against transients. Module-specific input protection, if any, is also provided to prevent damage to the module in case of inadvertent inputs or wrong wiring.

    Features common to all of the I/O modules of the RTU 6049-E70 :

  • Dual redundant high speed I/O bus
  • These I/O modules can be inserted into any of the backplane I/O slots for I/O exchange with CPU
  • Onboard 32-bit microcontroller
  • EMI/EMC Compliant
  • Hot swap capability
  • Local fault diagnosis
  • Isolation between field and logic
  • Surge Protection

IEC61850

HUSKY RTU supports both client and server functions. As a client, RTU can acquire real-time data from IEDs and transfer them over control-centre protocols such as IEC 60870-5-104. Thus, it can function as a gateway to modern Substation Automation Systems. This implementation is certified by UCA as per IEC61850 Ed.2.

As a server, the RTU can function to provide access to “legacy” I/O over IEC 61850 station bus by higher-order systems such as SAS.

System Redundancy

    RTU 6049-E70 supports redundancy of the following functions –

  • Rack power supplies – Supports installation of two power supplies in same rack for redundant operation
  • Processor module (incl. communication extender modules)
  • Communication channels towards master stations and IEDs

Processor Redundancy

RTU 6049-E70 supports dual redundancy of the processor modules by having a master-standby mechanism. Two options are available for implementing processor redundancy. First option allows installing of processor modules in separate racks, each with its own set of power supply and communication extender modules. In this scenario, I/O modules cannot be installed in the processor racks.

Both the processors are interconnected through the expansion bus. One of the processor modules assumes the role of the master CPU, while the other assumes the standby role. The master CPU performs all RTU functions including I/O scanning, communications, logic execution, etc. The standby CPU monitors the master CPU, and assumes the master role, in case the master CPU fails, and performs a cold start of the communication channels towards subordinate devices.

Communications Redundancy

Redundancy of communication channel between RTU and external world (IEDs and master stations) can be enabled in the RTU via Husky Studio. Redundancy of communication channels is based on active-passive concept, wherein one of the two channels is used for active communications, while the passive one is used for periodic health check of the link. When RTU detects failure of the active communication channel, it switches over to the passive channel making it active.

Communications

RTU 6049-E70 supports both serial-based and Ethernet-based communications on a variety of protocols. 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). These modules are installed alongside the processor module in the processor rack and communicate with the processor over the backplane bus.

    CXMs are available in two variants –

  • Passive - provides physical interfaces only, no processing capability
  • Active (Intelligent) - provides physical interfaces as well as protocol intelligence

RTU 6049-E70 supports traditional copper-based interfaces like RS232, RS485, 10/100-baseT Ethernet. Fiber-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. GSM/3G/4G modems and router modules are available for wireless communications.

Managed Ethernet switches as a rack-module is also available.

Time Synchronization

The RTU's Real-Time Clock (RTC) can be time synchronized from an external master clock like a GPS receiver over SNTP or serial-based ASCII (E.g., NMEA 0183) protocols. The RTU also supports time synchronization messages provided by SCADA protocols like IEC 870-5, DNP3.0, etc. HUSKY RTU supports up to eight time sources with various input possibilities including the above mentioned sources

Slave devices connected to the RTU can be time synchronized by the RTU using its RTC as the time base.
