ARStack Process Bus Simulator - Dual Firmware Stable
Public stable release promoted from operator-tested RC1.
Preferred Windows download: ARStack-Studio-win-x64-setup.zip.
Extract the ZIP and run the contained ARStack-Studio-win-x64-setup.exe.
Also available: a direct Setup EXE, Windows Portable ZIP, and Linux AppImage.
The executable for Studio, Linux AppImage, and both ESP32-P4 images are
bit-identical to the tested RC1. Only Windows stable-channel installer
packaging and release metadata changed. This is not a new firmware build.
Supports the existing IEC 61850 4I+4V SV simulation, SCL engineering profiles,
and GPS-style PTP Grandmaster simulation. The dual firmware bundle includes
separate pre-v3 and v3.x images with a verified revision-aware catalog.
The M4 three-MU software controls are integrated. Sustained 3x4000fps
field timing acceptance remains separate from the operator-tested RC1 release.
The v3.x firmware image is distributed as an ENGINEERING PREVIEW within this
stable Studio package: v3.x board/PHY boot, SV/PTP Ethernet capture, recovery,
autonomous operation and broad hardware compatibility are still undergoing
physical acceptance. Existing pre-v3 test evidence must not be presented as
v3.x evidence. The revision-aware catalog retains its original preview channel.
The Windows stable Inno installer has its own AppId; previously installed
Preview builds can be uninstalled separately after confirming stable works.
ZIP does not eliminate Windows SmartScreen/antivirus inspection of unsigned EXEs.
Use on an isolated laboratory process bus, never an energized protection system.
Historical M3.H.3 stable release and the user-tested RC1 are preserved.
