SCADA in European Power Company

Situation

A power utility company in Western Europe needed to be able to manage their SCADA (Supervisory Control and Data Acquisition) equipment remotely from a central office. This is because the company was on a trend towards decentralized power generation and a "smart grid" approach.

Solution

To do this while keeping costs low, they decided to piggy-back off of an existing IP, packet based network infrastructure. The Mini-RTU units only had RS232 interfaces and thus the data needed to be converted in some way to travel across the network.

The IP6810 provided this conversion box as well as the necessary software to uniquely identify its location on the network. In short, the IP6810 took care of the networking side while the mini-RTU took care of the SCADA control signals. Currently, the IP6810 is used in a point-to-point or point-to-multipoint application using its embedded Terminal Server function. In the future, the IP6810 can be configured as an self healing device in a ring topology to ensure network integrity.

Enterprises & Offices

While not as physically demanding as large factories, offices require strong communication networks as well. Many companies seek better ways to organize their traffic and this is where the IP6510-LN and the IP6610 can help. Our devices can add VLAN tags to direct traffic. They can also aggregate company leased lines for more efficient use. Vid...

Power Utilities

Global energy demand is growing, society's consciousness of greenhouse emissions is high, and climate changes can strain energy networks especially in hot summer months. The power industry has responded to these challenges with the development of a smart grid, a telecommunications infrastructure parallel to the power infrastructure. Loop Telec...

TDM over Ethernet

The move from a TDM (time division multiplexing) based network to an Ethernet or IP-based packet switched network is gradual and necessary in order to improve performance and keep costs down. However, this switch is being approached different ways depending on if the customer is a telecom carrier, utility, financial institution, or other indus...

As large companies grow, they increasingly need more dedicated internal infrastructure to communicate with their machines across large factories and between remote sites.Loop Telecom products such as the IP6820 are suited for these difficult environments -- it includes several GbE ports for high speed data transfer between data-hungry devices,...
