Read each row as: this output energizes when its input conditions are satisfied. Interlocks appear as NOT/inverted conditions — see the legend.

Every tag's read/write map across all routines. Filter to catch issues: Orphan — never read or written anywhere · Undriven — read by logic but never written · Multi-write — written in more than one place (possible conflict).

Safety and permissive tags — E-stops, faults, trips, bypasses — and the output coils they gate. Gates Outputs is how many outputs each one can block.

Advisory findings from the analyzer — not necessarily errors. Things worth a second look (orphaned tags, undocumented logic, unusual patterns), ranked by severity.

Every computed value in the logic — CPT and math expressions with their formulas and destination tags — pulled out so the calculations are visible in one place.

Decoded from Add-On Instruction (function block) calls in ladder logic — each card is one real equipment instance (motor, valve, PID, etc.). Call arguments are mapped to their real parameter names, and the AOI's own internal interlock logic is resolved to this specific instance's wired tags. Requires AOI definitions in the export — see the Add-On Instrs panel.

For each device type with 2+ instances, the standard wiring is derived from how the instances are ACTUALLY wired — then instances that don't match are flagged for review. This answers "are all my pumps wired the same?" — advisory, not errors: a flagged difference may be intentional (e.g. a different process area). One-off outliers are ranked above systematic groups.

Automated design-review checks on the decoded equipment model — the kind of pass a senior engineer does before FAT. Advisory, not errors: a flagged item may be intentional. Findings are ranked by severity; a clean pass is a real result (e.g. "nothing left in simulation"). Tell us if a finding is useful or intentional — that feedback sharpens the checks.

Compare the loaded file (Rev A) against a second export (Rev B) — what actually changed at the equipment level: devices added / removed / rewired / retyped, tags added / removed. Safety-relevant wiring changes (interlock, reset, alarm) are flagged. No more scrolling two Studio 5000 windows side by side. Both files are compared entirely in your browser.
