What it does
ModPedia is to Modbus devices what Wikipedia is to general knowledge: an open, community-edited reference where engineers document the devices they work with — register maps, data types, byte-order quirks, function-code support, and the hard-won field notes that never make it into a datasheet. Anyone can add or improve an entry.
Why we built it
Modbus is everywhere in industrial automation, but device-specific knowledge is scattered across PDFs, forum posts, and tribal memory. ModPedia gathers it into one searchable, citable place so the next engineer doesn't have to rediscover the same register offset the hard way.
Highlights
- Crowd-sourced entries for real-world Modbus devices
- Register maps, data types, and byte-order documentation
- Field notes and known quirks contributed by practitioners
- Open contribution model — add or edit any device
- Searchable, linkable reference
Status
ModPedia is a community project hosted by Softalink and grows with every contribution.
