TRACE 1.12.0 Beta

TRACE 1.12.0 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 1.11.1 Beta

• TRACE checks for a newer release once a day. A small, dismissible banner
  appears near the top of the window when one is found; dismissing it skips
  just that version, so a later release still notifies. The check is silent
  and never blocks the app if there is no internet access. Turn it off in
  Configuration ("Check for updates on startup"). A "Check for updates"
  button next to the version number in About runs the same check on demand,
  regardless of the daily check or a previously dismissed version.
• Browse PLC Tags asks for a bit when you pick a word tag. Selecting a
  scalar word (DINT/INT/SINT/WORD/BYTE/...), or an element of an array of
  words, now offers to pick a specific bit (0 to 7/15/31/63 depending on
  the type) instead of just the whole word — leaving it blank still adds
  the whole word, as before. Catches an invalid bit before it ever reaches
  the PLC, instead of only finding out from a "Path segment error" at read
  time.

Nothing else changed in TRACE itself.

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

before running it.

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 1.11.1 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.
