Electrical schematics, panel layout and reports
Industrial UI Schematic draws the schematics of control cabinets and the P&ID and pneumatic and hydraulic diagrams of the plant around them: IEC symbols and device tags, cross-references and wire numbers made for you, terminals, cables and PLC I/O, the mounting plate and every report — kept in one project on your computer.
What Schematic does
Schematics to IEC standards
Multi-page projects on A3 or A4 with a column band and a title block with revisions. A library of IEC 60617 symbols, your own symbols, and device tags with function, location and device (=PS+CAB1-K1) as in IEC 81346.
Cross-references and wire numbers
Coils and their contacts find each other: contact images under the coils and page/column references are kept up to date. Interruption points link pages, potentials run through them, and wires are numbered in one of four ways — new projects name each wire by its two ends, -K1:A1/-X1:3. Project → Check lists what does not add up.
Terminals and cables
Terminal strips with terminal parts and jumpers — side by side, or comb jumpers that skip terminals — and cables with their cores, cross-sections and lengths. The Terminals, Connections and Devices tables are live and lead to the place on the page.
More about terminals and cables →PLC I/O and SCADA
PLC channels with addresses, tag names, data types and alarms; addresses assigned in one go. The PLC I/O list goes into the reports, and the tag list exports as a file that Industrial UI SCADA imports.
More about PLC I/O and SCADA →PLC signal lists
Import the signal list of a PLC from Excel (CSV): each signal is drawn with a macro of its kind — switch, 3-wire sensor, 4–20 mA transmitter, valve — with its terminals and field device, page by page per module. When the list changes, import it again and see what will change first.
P&ID
Piping and instrumentation diagrams with ISO 10628 and ISA 5.1 symbols: valves, pumps, vessels, heat exchangers, instruments, line numbers with DN and medium. A pump on the P&ID is the same device as its motor on the schematic, with cross-references both ways.
Pneumatics and hydraulics
Fluid power diagrams to ISO 1219: directional valves of any kind from one dialog, cylinders, flow and pressure valves, air preparation, valve terminals. Each solenoid knows its coil on the schematic and the PLC channel behind it.
Parts from manufacturers
A parts database of your own, filled by importing the part data packages (.edz) that manufacturers publish on EPLAN Data Portal: data, pictures, function templates, schematic macros, front views and 3D models. Or describe a part yourself.
Panel layout
The mounting plate and the door at scale: DIN rails and ducts, devices with front views from their 3D data, snapping to mounting points, dimension lines, cable glands. Wire routes are drawn in the colours of the wires and can be dragged from duct to duct; potentials are wired in a chain or to a bus bar, and every length follows.
More about panel layout →Reports and PDF
Cover sheet, contents, parts and device lists, terminal diagrams, cable, connection and PLC I/O lists, made from the schematic. A vector PDF of the whole project or of chosen functions, locations or page types, with reports of their own; a wire list for cutting and markers for a marker printer.
Macros, views, light or dark
Typical circuits as macros: insert a motor starter or a power supply with its devices and wiring, and save your own. The Pages tab shows the project by function, by location, by page type or as a sortable list, and the program is light or dark — as the system, or as you choose.
Your projects stay with you
A local database, saved a second after each change, with versions you can go back to. One project moves as an .iusch file. Nothing is sent anywhere.
The example project — a pump station with 24 pages, a P&ID and a pneumatic diagram among them — opens from Help → Open example project. Every feature is described in the user guide.
Ask Claude to draw it
Industrial UI Schematic is an MCP server on your computer. Connect Claude Desktop or Claude Code to it, and Claude works in the project open in the program's window while you watch: it reads pages, draws circuits from a description, inserts macros, imports signal lists, places devices on the panel, checks the project and makes the PDF.
Each change is one step of Undo named “Claude: …”. No API key: Claude works on your Claude subscription. What Claude reads in the program becomes part of your conversation with Claude; switch it off in Help → Claude for projects that must not leave the computer. How to connect Claude.
Claude is a product of Anthropic. Industrial UI is not affiliated with Anthropic.
You ask, for example
- “Draw the control of pump 3 like pump 1: start and stop buttons, contactor -K3 latched, lamps for running and fault.”
- “Import this signal list” — Claude shows first what would change.
- “Name the vessels on the P&ID: hot liquor tank, mash tun, kettle.”
- “Put the new devices on the mounting plate, on the top rail.”
- “Check the project and fix what you can; then make the PDF.”
From the schematic to the cabinet
Works with Industrial UI SCADA
Give the PLC channels their tag names in the schematic, export the tag list (File → Export tags CSV) and import it into Industrial UI SCADA with Import CSV: the same addresses and names, no typing twice.

Requirements and licensing
Windows and macOS
Windows 10 or 11 (x64) and macOS 11 or later on Apple Silicon (Schematic on the Mac). One program with everything inside; it opens its own window and needs no internet.
One license, one computer
A license is bound to the hardware code of the computer. Schematic has its own code and its own license: a license of Industrial UI SCADA does not open it, and the other way round.
Free trial
The full editor for 90 days. You can renew a trial once while it is active. See pricing for paid licenses.
Checked offline
A license is a signed file checked on your computer. Schematic never contacts our servers.
Questions
Can it open EPLAN projects?
No. Schematic reads the part data packages (.edz) that manufacturers publish for EPLAN, so you do not have to type part data in. Projects are drawn in Schematic and saved in its own format.
Does working with Claude need an API key?
No. Claude Desktop or Claude Code connects to the program on your computer and works on your Claude subscription. Claude in a web browser cannot connect, because it does not see your computer. The program itself sends nothing anywhere.
Where are my projects?
In the program's database on your computer (schematic.db). Back it up by copying the file while the program is stopped, or export a single project as an .iusch file.
Can I use it in a browser?
Yes: while the program runs, the same editor opens at http://127.0.0.1:8790 — for a second screen or a second project. It is served by the program on your computer only.
What is in the user guide?
Everything in the program's Help → User guide: pages, drawing, devices, parts, terminals, cables, PLC, macros, the panel layout, reports and projects. Read it online.
