Control logic that leaves the editor as a drawing set.

FBD, CFC and SFC on titled A4/A3 sheets, with a project-wide link register and an interlock table that generates the logic. Export a linked PDF or one offline HTML file.

IntelliLogic on a dark theme: a function-block diagram with four input blocks feeding an AND gate and a pump output block, with the I/O point properties panel open on the right. — FBD canvas with a DI point selected. Screenshot: IntelliLogic 0.60.1, sample project.

01What's inside

The specifics, with numbers.

The things a general-purpose tool does not do.

Sheets you can hand over

A4 and A3 drawing frames, four title-block styles, sheet groups and numbering that survive export. Project metadata is entered once at project level.

A link register, not sticky notes

NET→ and →NET blocks share one project-wide register. Rename a link once; both ends resolve on every sheet.

The interlock table is the source

Import Excel or CSV, apply offline rules, and generate logic sheets from the rows. Change a row and the generated logic follows.

Typed I/O, not generic boxes

DI, AI, DO and AO blocks record how they are driven — toggle, push button, e-stop, selector, slider, numeric — and what the output does: lamp, alarm, pulse or readout.

Live values on the wire

Simulation writes one value per wire — boolean or analog, one per fan-out branch — so the consequence shows up on the sheet, not in a separate watch table.

An assistant that edits, not chats

A cloud model can drive the editor through its own tools, one undoable step at a time. It needs a configured model; the editor works without one.

02Gallery

A closer look.

Real screenshots where they exist. Where a capture is missing, the frame says so.

A complete A3 control sheet zoomed to fit: drawing frame, function-block diagram and title block in the lower right. — One A3 sheet at fit-to-page zoom, title block included.

The title block panel with labelled fields for project, sheet title, file number, designer, checker, approver and date, next to the drawing sheet. — Title-block fields sit next to the sheet they describe.

Logic Atlas: four control sheets laid out as clusters of coloured function blocks on a star-field grid, with a dashed cross-sheet link joining two sheets. — Logic Atlas with four sheets and one cross-sheet link, block colours keyed to block type.
