Kazam WMS · warehouse platform
In Sun Tech WCS the plant is not programmed: it is drawn. The web editor, served by the WCS itself, turns the drawing into the model on which the engine computes routes, and shows the plant while it works.
What it is
It is a web application served by the WCS at /editor, built on draw.io. It replaces the desktop editor of earlier versions, which is not part of the repository. You sign in with the same key as the API.
Drawing the plant
- A shape dropped on the drawing becomes a device; an arrow between two devices becomes a junction.
- Every device has its properties. There are windows for the list of devices and junctions, the missions, the commands, the WMS cells linked to the devices, the driver settings and the plant checks.
- Changes go through the same API every other system uses, with an exclusive edit lease, and most of them need the engine stopped or paused.
Watching it work
With the engine running the editor shows the state of the devices live and the load units on the drawing: the pallet moves from one device to the next while the WCS takes it to its destination.
The plant file
The whole plant can be exported and imported as JSON, and drawings from the old editor can be imported too; before replacing the plant the editor shows a comparison. Instead of the editor, the plant can be loaded straight through the API, as the sample plant's script does, and the two ways can be combined. The guide is Modelling a plant.
Browsers
The editor is verified on Chromium. Edge and Chrome are expected to work but not verified; Firefox and Safari have not been tried.
