- Industrial integrators working with Modbus devices
- Worth noticing
- The homepage lists 312 devices, 92 manufacturers, and 22,955 mapped registers with document provenance.
Field notes
The registry currently spans a notably broad manufacturer list, including ABB, Schneider, Siemens, Huawei, Socomec, and SolarEdge. Visible entries label maps as imported from documents and show individual register counts, while the homepage exposes a GET /api/devices endpoint. BusBabel also presents its coverage as expandable beyond Modbus, although the extract does not show additional protocols in operation.
