SEIM lets users design conveyor lines, simulate them in 3D, and export control logic for TwinCAT 3.

Landing page captured for the 2026-10-14 issue.

For: Conveyor and PLC-control engineers
Worth noticing: The browser preview saves projects only in that browser; desktop builds add folder-based saving and a command line for automated tests.

Field notes

The homepage labels the software version 0.9.1 and provides builds for Windows, Linux x64, Linux ARM64, and Apple silicon, each with a SHA-256 checksum. It says the browser preview stores projects in the current browser, while desktop builds add folder-based saving and a command line for automated tests. The site warns that the binaries are not code-signed yet.
