Socrate ingests electrical schematics (EPLAN and legacy), mechanical drawings, operator manuals, and now the PLC code itself, from any vintage of industrial machine, and binds them into a knowledge graph with traceable, deterministic reasoning. Built for the factories that exist, not the ones in the brochure.
They are scanned PDFs from 1998, DWG files with no layer hygiene, paper drawings with handwritten corrections, multi-vendor exports that never agreed on a naming convention. A parser that assumes EPLAN gives up here.
It is in the heads of the two or three senior engineers who have worked on these machines for twenty years. They will retire in the next five. They do not write things down. A wiki is not a strategy.
Electrical schematics, mechanical assemblies, and operator manuals describe the same machine in three different languages. The component -94B1 in the wiring diagram is the same photo-eye drawn in the mechanical layout and referenced in section 4.7 of the manual. Nothing currently binds them together.
Socrate is not a retrieval layer over your documents. It is a deterministic reasoning engine that operates on a knowledge graph built from your real schematics and your engineers' real expertise. Every answer is a reasoning chain you can audit node by node.
EPLAN, legacy DWG, scanned PDFs, hand-annotated paper, mechanical assembly drawings, multilingual operator manuals. Ingestion pipelines for the formats no one else has bothered to support.
Electrical references, mechanical components, and manual sections resolve to the same physical node in the graph. Ask about -94B1 and Socrate returns the wiring, the mechanical position, the datasheet, and the maintenance history as one answer.
Our knowledge engineers sit with your senior technicians during onboarding. Their reasoning becomes graph relationships. This is the only honest way to encode tribal knowledge before it walks out the door.
Every answer is a traced chain across the graph. No probabilistic retrieval. No "most likely relevant page." For regulated industries this is non-negotiable.
Four stages. Nothing in this pipeline depends on a model having memorized your machines. The output of each stage is human-inspectable.
Every format, every vintage. EPLAN, DWG, PDF, paper, manuals.
Human in the loop. Our knowledge engineers, with your senior technicians.
One graph across electrical, mechanical, and documentation.
Traced answers. Auditable end to end. Deterministic by construction.
Why does conveyor 3 stop intermittently on the night shift?
Socrate is vendor agnostic. It reads PLC code from any major platform, reconstructs the control logic, and binds every variable, timer and alarm to the physical component on the electrical schematic. Point at an alarm on the HMI and ask what it means. Socrate tells you why it fired, and exactly where in the schematic to look.
What does it mean, and where do I check?
At step 99 the vacuum in zone A never reached setpoint within the 8 s window while the pump was running. ALM_VUOTO is a genuine vacuum fault, not a sequence glitch.
The reasoning chain is the training material. New hires reach productive diagnosis on machines they have never seen before, without waiting for the one person who remembers the install.
Socrate surfaces the third time the same relay has stuck across three plants. Patterns the maintenance team could not see become procurement decisions the plant director can defend.
The drawer of paper drawings stops being a liability nobody wants to touch and becomes the most accurate map of how your machines actually behave.
Field service in remote conditions, every minute of downtime billable.
Schematic access from the cab, not the back office.
Safety-critical, audit-traceable maintenance under regulator scrutiny.
Every diagnostic comes with the chain of evidence behind it.
Air-gapped, classification-aware, reasoning chains that survive an audit.
Zero outbound traffic. No data leaves the perimeter.
Multi-vintage installed base, multi-vendor schematics, customers on three continents.
Service desk answers scale without growing the bench.
High-speed lines where intermittent faults cost more than the fix.
Root cause in minutes. Not after a teardown.
Plants whose schematics predate the people currently operating them.
Paper, scans, and DWG, ingested without rework.
Socrate runs entirely inside your network. Schematics, graphs, and reasoning chains stay on your hardware. We ship a signed appliance; you control the keys, the updates, and the audit log.
No cloud dependency required. Socrate runs inside your network, on your infrastructure.
For defense, aerospace, and regulated environments. Zero outbound traffic. Reasoning chains stay on site.
ISO 27001 in preparation. GDPR by design. EU AI Act aligned. Documentation available on request.
E-Plato is a team of engineers building Socrate for the industrial base that actually exists. We work directly with our customers' maintenance teams and senior technicians. We deploy on your premises, on your terms, with your data never leaving your network. We are deliberately European, deliberately specialized in industrial reasoning, and not interested in being a general-purpose AI vendor.
We will run Socrate on your worst legacy machine and show you the reasoning chain in a 90-minute session. No data leaves your premises.
