RELY-REC — network recorder
A network recorder that captures standard Ethernet, HSR and PRP traffic against a common time base. When a fault occurs you can reconstruct what happened, when and in what order, with nanosecond-accurate timestamps.

Overview
This is more than a packet capture appliance. It synchronises to the whole network over PTP or NTP and handles HSR/PRP duplicate frames correctly before recording. Where multiple devices work together, as in a substation or a factory, fault analysis breaks down if their clocks drift apart. RELY-REC records against a common time base, producing evidence that stands up to forensic examination. Captures are stored in PCAP and open directly in Wireshark.

Frequently asked questions
Yes. Captures are stored in PCAP format, so they open directly in Wireshark and other standard analysis tools.
Duplicate frames are recognised and handled, avoiding the double-counting that a simple mirror-port capture would produce.
Yes. Simultaneous read and write are supported, so past data can be retrieved without stopping the capture.
