LAN Tracker keeps an evidence-based history of which device held which IP, what DHCP told it and which ports answered, so you can reconstruct an incident after the fact.Sun, 18 Oct 2026 00:00:00 GMTannouncementtoolsnetworkingoperationshttps://otfabric.io/blog/introducing-modbus-trace-explorer/https://otfabric.io/blog/introducing-modbus-trace-explorer/Open a tcpdump or Wireshark capture of Modbus/TCP traffic and see latency per device, poll plans, exceptions, registers and connections.
