TRACE 1.13.0 Beta

TRACE 1.13.0 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 1.12.0 Beta

• Browse PLC Tags offers a member picker for structured tags, instead of
  typing one by hand. Rockwell's own TIMER, COUNTER and CONTROL always have
  the same members (PRE, ACC, EN, TT, DN, ...), so Browse now lets you pick
  one from a list, for a scalar tag or an array element alike, and sets the
  new tag up as Digital or Analog to match. For any other UDT or AOI, Browse
  now also shows its real members when it can resolve them, falling back to
  a text hint to add a member by hand only when that information genuinely
  isn't available (for example, a cached Browse result).
• Browse PLC Tags no longer gets stuck saying "No tags found." forever. A
  live query that came back with zero tags (the PLC or a bridge briefly not
  ready) used to get cached, so every later plain "Browse" click for that
  address replayed the empty result instead of asking again, with no way
  back to "Refresh from PLC". An empty result is no longer cached, so the
  next click tries again live.

Nothing else changed in TRACE itself.

• 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 1.12.0 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.

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.

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.

TRACE 1.11.0 Beta

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 1.10.2 Beta

New:

• A PLC address can include a port, for example 127.0.0.1:44819. Use it to
  read the virtual PLC that a ladder viewer publishes when FactoryTalk Linx
  already holds port 44818 on the same PC. A plain IP still uses port 44818.
• ControlLogix over USB, read-only, through RSLinx Classic. The 5580 USB port
  can only be opened by Rockwell software, so TRACE reads through the RSLinx
  Classic OPC server using a topic you set up in RSLinx (DDE/OPC > Topic
  Configuration). Requires RSLinx Classic with OPC. Tested on a 1756-L81ES:
  the values match the Ethernet readings and the connection recovers after
  the cable is pulled.
• Browse PLC Tags has a Scope column and filter (Controller or
  Program:<Name>). Program-scoped tags are read by their full name.
• Browse PLC Tags lists arrays with their size (DINT[50]). Picking one asks
  for the element index and fills in Tag[8].
• Help has a "Supported PLCs & Connections" page, also in the user manual.

Fixed:

• Selected rows in tag lists were almost invisible on Windows 11. The
  selection now uses the theme color in all three color profiles.
• Tag-name labels on the chart were hard to read when a curve of the same
  color passed behind them. They now have a solid background and sit above
  the curves.
• For PLCs connected over USB, a lost connection is now visible in the
  Monitor panel: a "Communication lost, reconnecting" notice, an amber band
  over the gap and "NO DATA" labels. The Log gets one line when the
  connection drops and one when it comes back, with how long it was down.

Support for SLC/MicroLogix and Siemens S7 PLCs is included but turned off.
It has not been tested on real hardware yet.

What changed since 1.10.1 Beta

Fixes to the Manage PLCs / Monitor interaction:

• New PLCs now start disabled instead of enabled by default.
• The status dot is retested on a recurring background poll instead of
  only once at the moment a PLC is enabled, so a connection that later
  drops or comes back is reflected (and logged) without the user having
  to touch anything.
• Deleting a PLC while one of its tags was being monitored live used to
  have no effect at all the reader kept running, and readding a PLC
  under the same name never reconnected anything. Both are fixed, and a
  panel now shows a visible "Signal(s) frozen PLC unavailable"
  indicator (not just a log line) when this happens.

docs/ and CHANGELOG.md for the full history, including the Simulation
