Cube SGC

The Cube SGC is a scalable communication and automation platform for demanding applications which is ideally suited for smart grids and industrial automation.

The modular hardware design allows for a varied configuration of I/O and communication modules allowing the Cube to handle multiple scenarios. The Cube can range from 1 to 4 cells with 2 modules per cell.

Based on a multi-tasking real-time operating system, the Cube’s powerful software platform can use various communication protocols and I/O modules, in conjunction with an integrated programmable logic controller to provide wide ranging communication and automation solutions.

Communication protocols including IEC 61850, IEC 60870-5-101/103/104, DNP3 and Modbus are part of an increasing communication application library available on the Cube SGC. Cloud interface options are based on JSON over MQTT exchange.

Infoteam’s OpenPCS programmable logic controller application is fully compliant with the IEC 61131 standard with all 5 programming languages and can be integrated as an option.

Standard Communication Features

Two configurable Ethernet ports provide a powerful network connectivity platform. Configuration options are:

  • 2 x Independent Ethernet ports with independent MACs
  • HSR (High Available Seamless Redundancy) Ethernet Ring
  • PRP (Parallel Redundant Protocol) Ethernet configuration

For local IED integration one (1) electrically isolated RS232 or RS485 communication port is provided. Two (2) additional serial ports can be integrated as an extension module.

Additional Communication Options

Cloud computing, wide area and wireless networks will become an integral part of utility communication networks. For these interfaces various communication channels are in development to be added to the Cube SGC as hardware modules, including:

  • Cellular networks (3G, 4G/LTE)
  • 2 port serial extension (independent RS-232 and RS-485)

Local I/O and extensions

The Cube is available in sizes up to 4 cells, each cell supporting 2 module cards, making 8 available slots per Cube. Other than the power supply and processor boards, the following cards are available:

  • 8x filtered digital inputs
  • 4x digital inputs and 2x relay outputs
  • 4x relay outputs (1 change over)
  • 4x analog inputs with DC current measured from -22mA to +22mA, and DC voltage from -11V to +11V 

Integrated Software

The Application Data Hub (ADH) has been integrated which includes support for communication protocols IEC 61850, IEC 60870-5-101/103/104, DNP3, Modbus, JSON/MQTT and local I/O and extension cards. The integrated IEC 61131 compliant Infoteam SmartPLC application allows the user to develop their own automation logic. 

The Cube SGC is configured using eNode Designer, which links in with the IEC 61131 compliant OpenPCS development tool to allow for easy programming of automation logic.

By using our IEC 61850 ICD Designer tool to the eNode Designer implementing IEC 61850 applications becomes an achievable engineering task using the complete IEC 61850 modeling.
