Read the PLC directly.
Live tag values reveal what is happening at the controller when a fault occurs, through a diagnostic connection with no write path.
Built in the field. Now opening to early adopters.

DeltoriPro reads live PLC data, maps it to your machine logic, and explains what broke, why it matters, and what your team should check next.
FOLLOW THE FAULT
Follow a planer-infeed start fault from the pushbutton input to starter contacts and auxiliary feedback, with PLC program context beside the conversation.
01 / THE KNOWLEDGE GAP
A stopped line. A cryptic alarm. The one person who understands the logic is off shift.
Other tools tell your team where to look. DeltoriPro reads the PLC directly, connects live machine data with program context, and shows what failed, where to verify it, and how to move the right people toward a fix.
02 / THE DELTORIPRO PLATFORM
Your program. Your process. Your live controller context.
Live tag values reveal what is happening at the controller when a fault occurs, through a diagnostic connection with no write path.
Connect the active state to your PLC program. Follow interlocks, dependencies, and rung references behind the alarm.
Plain language for operators. Tag names and rung references for controls staff. One source of context, adapted to the work.
MACHINE PROFILE WORKFLOW
Start with your Allen-Bradley program export. Follow the routines, rungs, tags, and analysis into a candidate machine profile. Your team reviews and approves the candidate before publication; a completed build does not automatically replace approved context.
04 / SYSTEM ARCHITECTURE
Explore read-only PLC access, secure outbound data flow, and customer-isolated services—from one workstation to the whole plant.
Read-only access gathers controller data across production lines. PLC logic and control remain at the equipment in any industry.
PATENT PENDINGCloud-connected deployments shown. Network access and data residency are scoped with your IT/OT team.
THE WORKFLOW
Connect read-only to a supported Allen-Bradley controller. Confirm the model, program export and network requirements with our team. Siemens, AutomationDirect and CODESYS remain on the roadmap.
Bring live tag values and machine logic together. Follow the evidence behind the fault instead of rebuilding context by hand.
Give authorized personnel the plain-language answer, rung references, and next checks needed to verify the finding under site procedures.
THE OPERATIONAL SHIFT
The opportunity is less time searching through tools, and more time acting on controller-grounded evidence.

DeltoriPro reads the PLC context directly and gives the team a shared starting point for verification.How DeltoriPro complements HMI, PLC, and maintenance workflows your team already uses.
| Investigation | Conventional workflow | With DeltoriPro |
|---|---|---|
| Starting point | An alarm or fault code | The fault, live tag state, and machine program |
| Investigation | Find context across separate tools | Follow connected logic and tag references |
| Explanation | Interpretation depends on the reader | Role-adaptive language with technical evidence |
| Control boundary | Defined by each tool and workflow | A diagnostic connection with no PLC write path |
| Platform context | Vendor tools, HMI screens, and manual exports | Allen-Bradley supported; Siemens, AutomationDirect and CODESYS on the roadmap |
APPLICATIONS & INTEGRATIONS
Explore industrial applications, then confirm the controller models, program formats, and network requirements for your site. These examples illustrate possible investigations, not measured customer outcomes.
Allen-Bradley integration is supported. Siemens, AutomationDirect and CODESYS are on the roadmap.
When a conveyor stops or a planer infeed stalls, investigate the run request, permissives, and auxiliary-contact feedback beside the machine's program references. Scope the application around your mill's supported Allen-Bradley controls.
Discuss your mill's controls ↗Explore cooling-loop pumps, mechanical-support sequences, and drive-ready feedback with machine-specific PLC context. Compare requests, enabling conditions, and feedback before identifying the next check, within your site's agreed scope.
Scope your infrastructure use case ↗Follow crane travel requests, drive-ready feedback, and permissive chains through the installed PLC program. Give maintenance and controls teams source-linked context for investigation; the diagnostic connection does not issue control commands.
Discuss your port equipment ↗SUPPORTED TODAY
Connect PLC program context and read-only controller data with the questions your team asks on the floor. Confirm your specific controller, program export, and network configuration with the Deltori team.
Confirm your controller requirements ↗ON THE ROADMAP
These are planned integrations, with no committed release dates. Tell us which controller family and application you need so we can discuss scope. A protocol name alone does not establish controller compatibility.
Discuss a planned integration ↗05 / BUILT AROUND YOUR PEOPLE

Follow the fault to the signals and logic that matter. Give your technicians a focused starting point, with the evidence attached.
06 / BUILD THE BUSINESS CASE
Use the sliders to explore the value of less time spent diagnosing controls faults.
Enter your downtime cost and diagnosis hours. This estimate assumes a 50% reduction in diagnosis time.
96 hours of diagnosis-related downtime per year × 50% estimated reduction × $28,000/hour.
Scenario estimate, not a performance forecast or guaranteed savings. Excludes subscription, implementation, and other costs. Actual results depend on fault mix, response time, and site conditions.
07 / BEFORE YOU CONNECT
From controller compatibility to deployment boundaries. Start here, then bring us your plant-specific questions.

Developed from controls integration experience in sawmills, planer mills, and industrial operations.

The answer was always inside the PLC. Nobody on shift could get to it.
After more than a decade commissioning and troubleshooting industrial controls, Shane Dickerson built DeltoriPro to put machine knowledge in the hands of the people on the floor.
