Cube Controller SGC-30

The SMART Grid CUBE Controller SGC-30 is a scalable communication and automation platform for demanding SMART Grid applications, which is ideally suited for micro grids, smart grid applications and distribution automation.

Based on a multi-tasking real-time operating system, a number of communication protocols the device can be used in conjunction with an integrated programmable logic controller.

Communication protocols such as IEC 61850, IEC 60870-5-101/103/104, DNP3 and Modbus are part of a standard communication library available on the SGC-30. Cloud interface options are based on standard JSON/MQTT data format and exchange.

Infoteam’s OpenPCS programmable logic controller application is fully compliant with the IEC 61131 standard.

Standard Communication Features

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

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

For local IED integration one (1) electrically isolated RS232 or RS485 serial communication port is provided.

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 can be added to the SGC-30 as cube cells, including:

  • GSM, 3G, LTE
  • Lora WAN
  • Wireless Ethernet
  • Bluetooth

Local I/O and extensions

The CUBE is available in sizes up to 4 functional cells, each cell supporting 2 module cards, making 8 available slots per SGC-30. Other than the power supply and processor boards, the following cards are available:

  • 8 filtered digital inputs
  • 4 digital inputs and 2 relay outputs
  • 4 relay outputs
  • 4 analog inputs with DC current measured from -22mA to +22mA
  • Wireless temperature and partial discharge monitoring: up to 32 wireless temperature sensors and 3 partial discharge detection locations.
  • Cellular (3G/4G/..) and LoRa interface
  • 3x Ethernet port switch extension
  • 2x Serial extension (independent RS-232 and RS-485)

Integrated Software

The Application Data Hub (ADH) has been fully 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 Controller 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 linking our IEC 61850 ICD Designer tool to the eNode Designer implementing IEC 61850 applications becomes a simple and easily achievable engineering task.
