Practical topics around EupCAD: schematic drawing in the browser, IEC 81346 addressing, BOM and reports.
A terminal number is the postal code inside the panel. When two conductors land on the same number, the error works silently. In EupCAD the terminal schedule is produced from the drawing, and a repeated number lands in the rule check report.
Read moreWhen two people draw the same circuit, you get two contactors, two fuses, two drawing styles. EupCAD's built-in library ships with 802 IEC 60617 symbols; a custom symbol is added to your own library.
Read moreWhat changes hands at a panel handover is a package, not a drawing: the drawing, the BOM, the terminal, cable and I/O lists. In EupCAD these documents are produced from the same source; no document in the package can be older than the others.
Read moreFinding the answer to 'how many cores, and where does this go?' in the drawings takes hours while cabling. In EupCAD the cable list comes off the drawing in one click, numbers are assigned automatically, and the core count is checked by the rule check.
Read moreWithout a part number, which contactor is which is left to guesswork at the purchasing desk. In EupCAD the device data is kept with the drawing; the BOM is grouped by part number, and the gaps are flagged in the report.
Read moreRunning desktop CAD in the field hits three walls: no permission to install, a weak connection, and the file leaving the company. EupCAD opens in the browser, works offline, and the project file never leaves your device.
Read moreThe device changed, but the BOM still shows the old part. In a revision, the real cost is the manual work between drawing and list. With one data source, a change updates the drawing and every list — no forgotten rows.
Read moreAs signals spread over ten pages, a hand-maintained I/O table stops holding up. EupCAD produces the I/O list in one click from the device mapping; the design rule check catches address conflicts before the field does.
Read moreThe most expensive error is the one found during cabling on site. EupCAD's design rule check reports address conflicts, short circuits and protection mismatches — with page numbers — before commissioning starts.
Read moreA contactor here, its coil over there; the hand-maintained cross-references drift a little more with every revision. EupCAD derives references from the tag: one source, no second copy — a reference can never detach from the drawing.
Read moreIEC 81346 multilevel designation gives every device and terminal a readable address. In EupCAD the tag is the device's classification data: change the tag and address, terminals and reports all update together.
Read moreSkip the desktop CAD install, license key and file-shuffling. EupCAD lets you draw electrical schematics, generate a BOM and keep your project on your device — your first schematic in under 5 minutes.
Read moreStop transcribing the BOM, terminal schedule and cable list into Excel by hand. EupCAD generates device, terminal, cable and PLC I/O lists as CSV with a single click — part number, manufacturer and quantity in the table.
