Claude

Claude, the AI assistant of Anthropic, can work in this program: read your projects, draw schematics from a description, insert macros, import signal lists, choose parts, place devices on panel layouts, check the project and make the reports and the PDF. It works in the project open in the program's window, and you see each change as it is made.

Connecting Claude

The program is an MCP server (Model Context Protocol) on this computer: Claude Desktop or Claude Code connects to it while the program runs. No API key is needed; Claude works on your Claude subscription. Open Help → Claude…:

• Claude Desktop (macOS, Windows): quit Claude Desktop (macOS: Claude → Quit Claude, ⌘Q; Windows: right-click its icon by the clock → Quit), click Add to Claude Desktop, then start Claude Desktop. Its tools then include Industrial UI Schematic. The button adds the program to Claude Desktop's settings and keeps the servers that are there. It does nothing while Claude Desktop runs: Claude Desktop keeps its settings in memory and would write over the change.
• Claude Code: run the command shown (Copy puts it on the clipboard):

claude mcp add --transport http iui-schematic http://127.0.0.1:8790/mcp

Claude in a web browser (claude.ai) cannot connect: it does not see this computer.

Claude may connect in the same window switches it off and on. Switched off, Claude's tools answer that the program does not let them in.

What to ask

Talk to Claude as to a colleague who knows the program:

• "Open the project Pump station 2 and tell me what is in it."
• "On a new page draw the control of pump 3 like pump 1: stop and start buttons, contactor -K3 latched, lamps for running and fault."
• "Draw a direct-on-line starter for a 5.5 kW fan in column 6 of page 2, with parts from the database."
• "Import this signal list" (paste the list): Claude can show first what would change.
• "Put the new devices on the mounting plate, on the top rail."
• "Give terminals 1 to 8 of -X1 the part PXC.3031212 and PE1 the PE terminal; -X1 gets two end plates."
• "Name the vessels on the P&ID: hot liquor tank, mash tun, kettle." (Claude writes texts beside them and can change the number, size and flow arrow of a line.)
• "Check the project and fix what you can; then make the PDF."

Claude draws circuits top to bottom, as they are drawn here: the supply at the top, switches and contacts, the coil or lamp, the return at the bottom; the program puts each element under the one before so that they connect, and Claude adds wires for branches. It looks at the pages it drew to check them.

What you see

• Each change is one step of Undo, named Claude: … (Edit → Undo takes it back as any other step). Claude's own undo takes back only its steps, never yours.
• The status bar shows what Claude is doing.
• A project open read-only (edited in another tab or window) stays as it is: Claude is told so.
• PDFs and lists Claude makes go to the exports folder next to the database; Open exports folder in Help → Claude… shows it. Claude writes no other files.

Your data

The program sends nothing anywhere by itself. But what Claude reads in the program — tags, descriptions, the data of parts, pictures of pages — becomes part of your conversation with Claude, as anything you type there; Anthropic's terms for Claude apply to it. Switch Claude off in Help → Claude… for projects that must not be shared.
