net-line FW-5-GATE-4G

Powerful micro RTU for applications with intensive communication skills

The comprehensive monitoring and control of supply networks and other large infrastructures is not economically viable without a mobile radio connection. The net-line FW-5-GATE-4G brings together powerful telecontrol technology based on the latest series5e generation of CPUs with an LTE modem for flexible mobile radio connection. As with all FW-5 series remote terminal units, the FW-5-GATE-4G can be Extended with I/O extension boards and interface modules in top-hat assembly. This makes it easy to implement compact telecontrol systems with the exact required capacity.

The safe Connection

The FW-5-GATE-4G allows for a high degree of IT security according to the requirements of the BDEW whitepaper and BSI recommendations. It is based on the new series5e CPU generation. Thanks to the processor speed of 1200 MIPS it has enough power; also with respect to future challenges. The improved performance in particular has a positive impact on network communication via IEC 61850 and process point treatment according to IEC 60870-5-10x standards. The overall system was based on a modern Linux kernel which allows greater flexibility for continuous improvement, especially in terms of IT security.

FW-5-GATE-4G - All in one: Telecontrol unit, router, gateway and modem

The parameterisation software setIT provides quick commissioning and high compatibility with telecontrol systems. Thanks to full configuration of all components of the FW-5-GATE-4G device in setIT, there is no need to integrate or adapt an external modem, which can be time-consuming. Up to 8 VPN tunnels with end-to-end-encryption can be set up from the station. In addition, all available information from the mobile radio module can be used in the setIT diagnostics functions.

Typical application areas

  • Intelligent local network stations with integration of power measurement devices, ground-/short circuit indicators, network analysis systems and protective equipment
  • Feed-in management in renewable energy plants
  • Control box for direct marketing and control energy
  • Intelligent measurement point for wide range regulation in distribution networks
  • Monitoring of media and infrastructure systems in pipelines
  • Controls for street lighting
  • Merging virtual power stations using VHPready

series5e IT security

series5e technology allows for comprehensive IT-Security measures as required in the current requirement profiles of the BDEW whitepaper and BSI recommendations. Security is verified using audits from renown consultants and offices backed up by periodical internal penetration tests.
