EdsDcfNet

A comprehensive, easy-to-use C# .NET library for CiA DS 306 - Electronic Data Sheet (EDS), Device Configuration File (DCF) and Nodelist Project (CPJ) for CANopen devices.

Features

✨ Simple API - Intuitive, fluent API style for quick integration

📖 Read EDS - Complete parsing of Electronic Data Sheets

📝 Read & Write DCF - Process and create Device Configuration Files

🌐 Read & Write CPJ - Parse and create Nodelist Project files (CiA 306-3 network topologies)

🔄 EDS to DCF Conversion - Easy conversion with configuration parameters

🎯 Type-Safe - Fully typed models for all CANopen objects

📦 Modular - Support for modular devices (bus couplers + modules)

✅ CiA DS 306 v1.4 Compliant - Implemented according to official specification

Quick Start

Reading an EDS File

using EdsDcfNet;

// Read EDS file
var eds = CanOpenFile.ReadEds("device.eds");

// Display device information
Console.WriteLine($"Device: {eds.DeviceInfo.ProductName}");
Console.WriteLine($"Vendor: {eds.DeviceInfo.VendorName}");
Console.WriteLine($"Product Number: 0x{eds.DeviceInfo.ProductNumber:X}");

Reading a DCF File

using EdsDcfNet;

// Read DCF file
var dcf = CanOpenFile.ReadDcf("configured_device.dcf");

Console.WriteLine($"Node ID: {dcf.DeviceCommissioning.NodeId}");
Console.WriteLine($"Baudrate: {dcf.DeviceCommissioning.Baudrate} kbit/s");

Converting EDS to DCF

using EdsDcfNet;

// Read EDS
var eds = CanOpenFile.ReadEds("device.eds");

// Convert to DCF with node ID and baudrate
var dcf = CanOpenFile.EdsToDcf(eds, nodeId: 2, baudrate: 500, nodeName: "MyDevice");

// Save DCF
CanOpenFile.WriteDcf(dcf, "device_node2.dcf");

Working with Nodelist Projects (CPJ)

using EdsDcfNet;
using EdsDcfNet.Models;

// Read a CPJ file describing the network topology
var cpj = CanOpenFile.ReadCpj("nodelist.cpj");

foreach (var network in cpj.Networks)
{
    Console.WriteLine($"Network: {network.NetName}");
    foreach (var node in network.Nodes.Values)
    {
        Console.WriteLine($"  Node {node.NodeId}: {node.Name} ({node.DcfFileName})");
    }
}

// Create a new CPJ
var project = new NodelistProject();
project.Networks.Add(new NetworkTopology
{
    NetName = "Production Line 1",
    Nodes =
    {
        [2] = new NetworkNode { NodeId = 2, Present = true, Name = "PLC", DcfFileName = "plc.dcf" },
        [3] = new NetworkNode { NodeId = 3, Present = true, Name = "IO Module", DcfFileName = "io.dcf" }
    }
});
CanOpenFile.WriteCpj(project, "network.cpj");

Working with Object Dictionary

using EdsDcfNet.Extensions;

var dcf = CanOpenFile.ReadDcf("device.dcf");

// Get object
var deviceType = dcf.ObjectDictionary.GetObject(0x1000);

// Set value
dcf.ObjectDictionary.SetParameterValue(0x1000, "0x00000191");

// Browse PDO objects
var tpdos = dcf.ObjectDictionary.GetPdoCommunicationParameters(transmit: true);
