Description

RELY-REC is a small and cost effective device, provided with the recording and networking capabilities of a leader high-end recorder. Thanks to its robust design based on industrial grade components, it can be installed in an unattended way in any critical site. The heart of this equipment is a multi-CPU FPGA that makes the device one of the most powerful and flexible options available in the market

In critical systems, it is essential being able to analyze the network communications at frame level for testing and forensic purposes. Furthermore, the validity of this analysis will be constrained by the capability of the infrastructure to correlate the frames with a common time reference. For that purpose, Relyum has developed RELY-REC, a device that is able to inspect, timestamp and record regular Ethernet and high-availability Ethernet traffic, using the same PTP timing reference than the network under analysis.

As an example, due to the critical nature of communications in Electric sector, RELY-REC is an all-in-one solution specifically designed to analyze the traffic in the modern IEC 61850 Digital Substations where the use of combined HSR, PRP and PTP has generated a new challenge for the operators. This device is synchronized with a IEEE 1588-2008 PTPv2 infrastructure, that may be the same shared by the other equipment of the substation.
