Write a function block once, version it, and ship it to every machine you build. A Sysmac library is how good code stops being copy-pasted and starts being maintained — across a whole fleet, from one source.
A library carries a version. Bump it and you add features without breaking machines pinned to the old one. Step through MyConveyorLib's releases — new FBs light up as they're introduced.
// your project's own block belt : FB_Conveyor; // the library's block — qualified belt2 : MyConveyorLib\FB_Conveyor;
The \ namespace prefix tells Sysmac exactly which FB_Conveyor you mean — no accidental collision when two libraries pick the same name.
📥 Repository → reference. You install a library into the repository once, then reference a specific version from each project. Update the reference to roll a machine forward.
🚢 One source, whole fleet. Fix a bug in the library, publish v2.0.1, and every machine that references it upgrades on its next build — instead of editing 40 copies by hand.
Two libraries both define a block called FB_Timer. How do you use the one you mean without a clash?
