Module profirust::dp

DP - Decentralized peripherals

This module implements the DP application layer of PROFIBUS. The main component is the DpMaster type which manages the DP cyclic communication and peripheral lifecycle.

Peripherals are represented as Peripheral objects which you need to construct using PeripheralOptions. These options are best generated from the peripheral’s GSD file using the gsdtool that is part of the profirust project.
