PLC Inspect
Inspect a Rockwell PLC project
Point Glyphsix at any L5X export and get a full structural summary — programs, routines, tags, UDTs, modules, and communication topology.

Controller 1756-L83E/B CompactLogix
Programs 3
Routines 18 (12 Ladder, 4 ST, 2 FBD)
Tags 892 controller-scoped, 246 program-scoped
UDTs 21 user-defined types
AOIs 6 Add-On Instructions
Modules 8 I/O modules on 2 racks
Program summary:
MainProgram 8 routines 312 tags Ladder + ST
Comms_Handler 6 routines 145 tags ST
Safety_Task 4 routines 87 tags Ladder

HMI Inspect
Inspect an encrypted HMI project
Glyphsix decrypts proprietary HMI files and extracts panels, widgets, variables, alarms, and recipes — no vendor software required.
$ glyphsix-hmi inspect REACTOR7_v4.zdat
Provider Vijeo Designer 6.2 (Schneider Electric)
Encrypted Twofish-256 CBC ✓ decrypted
Panels 14 panels (3 popups)
Widgets 284 total across all panels
Variables 167 internal, 43 external
Alarms 23 alarm groups
Recipes 7 recipe definitions
Panel summary:
Main_Overview 42 widgets 12 bindings
Reactor_Control 38 widgets 9 bindings
Temp_Monitoring 31 widgets 15 bindings
Alarm_History 28 widgets 3 bindings
Recipe_Editor 25 widgets 8 bindings
... 9 more panels
✓ Project parsed in 1.2s
Diff
Diff two project versions
Compare any two project files from the same vendor and see exactly what changed — added routines, modified tags, updated logic — with colorized, structured output.
$ glyphsix-plc diff WaterTreatment_v2.1.L5X WaterTreatment_v2.2.L5X
Comparing versions...
Routines:

Cross-Validate
Validate HMI against PLC
The real power: pair an HMI project with a PLC export and find phantom variables, orphaned bindings, name mismatches, and type conflicts that live in the gap between systems.
$ glyphsix validate --hmi REACTOR7_v4.zdat --plc WaterTreatment.L5X
HMI: Vijeo Designer 6.2 (Schneider Electric)
PLC: Rockwell Logix 5000 (Studio 5000 v33)
Running 12 validation rules...
✓ Panel naming conventions passed
✓ Widget bounds check passed
✓ Alarm severity mapping passed
✓ Duplicate widget IDs passed
✓ Recipe parameter types passed
✓ Navigation graph passed
✓ Localization keys passed
✓ Variable data types passed
⚠ Orphaned variables 2 found
ReactorTempSP_Old (INT) — defined in HMI, not bound to any widget
SpareInput_03 (BOOL) — defined in HMI, not bound to any widget
⚠ Cross-ref HMI ↔ PLC 3 mismatches
HMI:Tank_Level → PLC:TankLevel (name mismatch)
HMI:Pump_Status → PLC:Pump_Run (type mismatch: STRING vs BOOL)
HMI:Spare_04 — no matching PLC tag found
✗ Address overlap 1 conflict
%MW200 mapped to both Pressure_PV and FlowRate_PV
Result: 8 passed, 2 warnings, 1 error
✓ Validation completed in 2.3s
