Overview The CanopenStorage library provides an interface to manage and interact with CANopen networks. It facilitates communication with nodes using Service Data Objects (SDO), Process Data Objects (PDO), and supports network management via Node Management States (NMT). The library is designed for integration with a backend storage system, logging, and error handling mechanisms.

Features

CANopen Network Initialization

Scans and initializes nodes in the network. Supports both local and remote nodes. Automatically configures node mappings and states.

PDO Communication

Handles PDO data reception and transmission. Generates and transmits PDO messages based on mapping configurations.

SDO Communication

Reads and writes variables using SDO. Supports retry mechanisms for reliable communication.

Emergency (EMG) Handling

Processes and logs emergency messages. Updates active error lists with reactions and timestamps.

NMT State Management

Retrieves and updates node states in the CANopen network.

Backend Storage Integration

Reads and writes variables from/to a backend storage system. Supports mapping between variables and object dictionary entries.

Logging

Provides detailed logging for CANopen operations and error handling.
