The AJ71 PB92 has a physical layer, data link layer, DDLM, and user interface
that conform to PROFIBUS-DP, and communicates data with the PC CPU by
using a buffer memory.
The main application of PROFIBUS-DP is networks that execute high-speed
communication at the level of sensors and actuators, and the AJ71 PB92 has
been designed with this in mind: its functions are mainly related to data I/O
with slave stations.
