A live map of every interlock in the PLC and DCS.
MACLOGIC reads the exported programs of your controllers and shows what the logic really does today: which critical interlocks are bypassed, what changed since the last export, and what trips each motor, down to the field signal. It reads files only and never connects to a controller.
Six ways MACLOGIC knows your plant, not a generic checklist
Every trip, permissive and sequence stop in your rungs.
Jumpered, switched off, forced or simulated, at every export.
Each trip traced to the input, alarm or timer behind it.
Every export compared with the last: a logic historian for the plant.
One tab per department, quarry to packing, each with a status.
Functional description rebuilt from the logic, in Word.
Backups store the logic. Studio 5000 shows it. MACLOGIC explains it.
Your functional description, reverse-engineered from the PLC
FD missing, or no longer matching the logic? MACLOGIC writes one per department in Word, ready to review and sign: control philosophy, start order worked out from the interlocks, stop sequence, and every interlock with its rung, timers, loops, limits, alarms and bypasses. Anything the logic cannot tell is marked for your engineer.
What MACLOGIC solves
Bypasses get forgotten, interlocks change without anyone noticing, and nobody can answer 'what trips the coal mill?' without opening the logic. Functional descriptions go missing or stop matching the logic. That is a safety and reliability risk.
What it does
- Bypassed and changed interlocks, with their age and owner
- Design, logic and behavior checked against each other
- Answers questions such as “what trips the coal mill?”
- Daily report, and nothing it runs can write to a controller
What it finds
- Bypassed interlocks: jumpered, switched off or held by a selection
- Defeated signals: disabled alarms, forces, simulation
- Logic changes: conditions, limits and timers, by rung
Answers for every role
- Ask in plain words: “what trips the kiln ID fan?”
- If this stops: what else stops, and what must run first
- Bypass register: who approved it, why, and until when
- Daily and weekly reports for management
What plants get from it
- No silent bypasses: each one ranked, with an owner
- Fewer surprise trips: changed trips and timers caught
- Audit-ready: bypass log and change history for MOC
- Management kept informed with daily and weekly reports
Simple to run
- Windows PC, fully offline, and your logic stays on site
- Allen-Bradley today; Siemens and Honeywell coming
- Annual subscription per plant, with a free 3-department trial
- Part of MAC Suite: findings feed MACPIA and MACDATA
Send us one export. We'll show you what is bypassed.
From your exports to a daily watch
First audit in a week
One L5X export per controller in a pilot area, plus your design interlock list.
Every interlock mapped, every bypass and change found, reviewed with your engineers.
Installed on site: a daily report every morning, and the bypass register in use.
Every department covered, with a functional description for each.
