TRACE 1.11.1 Beta

TRACE 1.11.1 Beta

Free Windows desktop application to monitor, record, and replay Allen Bradley
PLC signals over EtherNet/IP, with Chain Map diagnostics, a connector pinout
reference, and a built-in simulation mode for practicing without a PLC.

What changed since 1.11.0 Beta

• Siganor Link is now installed with TRACE. It connects TRACE to the online
  Siganor Simulator at https://sim.siganor.com: the simulator publishes its
  tags as a virtual PLC on this PC, and TRACE reads them like any Logix PLC.

  1. Start Siganor Link from the Start menu (TRACE > Siganor Link). Its
     window shows a pairing code.
  2. In the simulator, turn on Publish as PLC and enter that code once. The
     first time, Chrome and Edge ask whether the site may access devices on
     your local network: allow it.
  3. In TRACE, use the address the simulator shows (for example
     127.0.0.1:44818) as the PLC IP.

  Siganor Link listens on this PC only and accepts the simulator only after
  the pairing code is entered.

• The third-party notices now list python-snap7, pycomm3 and comtypes (MIT,
  included since 1.11.0) and the Node.js runtime inside Siganor Link.

Nothing else changed in TRACE itself.

TRACE is developed and distributed by Wilmer Ramirez Gutierrez, an
independent software developer, under the Siganor name.

Before you install

• This build is unsigned, and so is Siganor Link. Windows SmartScreen will
  most likely warn that it is an "unrecognized app". That is expected for an
  unsigned build from a small independent publisher. Do not disable
  SmartScreen or Defender to get past it; if that is not acceptable to you,
  don't install. The installer also shows this notice on its own page.
• Beta for simulation and lab use. Use it on plant equipment only with the
  approval of your industrial security team. A matching SHA-256 shows the
  file is the one published here; it does not prove who published it.
• This is Beta software. Check results independently before using them to
  make decisions about equipment or production. TRACE is not a safety system
  and does not replace approved engineering procedures. Simulation mode and
  the online simulator are for practice, not for validating real behavior.
• Per-user install, no admin rights required (%LOCALAPPDATA%\Programs\TRACE).
  Your data lives in %LOCALAPPDATA%\TRACE and uninstalling does not touch it.
  Installing over 1.11.0 keeps your configuration.
• The installer's license page shows EULA.md. Some fields in it (Licensor
  address, governing jurisdiction, liability cap amount) are still open.
