The Fuji protocol was developed by Fuji Electric for communication between control stations and substations.

The physical layer is based on a proprietary 28-bit PCM format.

Fuji operates in half-duplex mode based on the master/slave principle. While one master can communicate with up to 32 RTUs, each RTU only responds to explicit requests from the master.
