ih-lib60870-node

A cross-platform Node.js native addon for the IEC 60870-5 protocol suite, enabling seamless communication with industrial control systems, SCADA, and RTUs. Built with node-gyp and prebuild, this addon ensures compatibility across multiple operating systems and architectures.

---

✨ Features

• IEC 60870-5 Protocol Support: Implements key functionalities of IEC 60870-5 standards (e.g., IEC 60870-5-101/104) for robust industrial automation communication.
• Cross-Platform Compatibility: Supports Windows, Linux, and macOS with prebuilt binaries for x64, arm, and arm64 architectures.
• High Performance: Native C++ implementation optimized for low-latency and reliable data exchange.
• File Transfer: Supports file transfer operations in both monitoring and control directions.
• Flexible Integration: Easy-to-use APIs for integration with Node.js applications, SCADA systems, or custom control solutions.
• Prebuilt Binaries: Includes precompiled binaries for Node.js v20, simplifying setup and deployment.

🚀 Installation

1. Ensure you have Node.js v20 installed.

2. Install the package via npm:

   npm install ih-lib60870-node --ignore-scripts

3. Prebuilt binaries will be automatically downloaded for your platform and architecture. If a prebuilt binary is unavailable, the addon will be compiled using node-gyp, requiring:

   • Python 3.11+
   • A compatible C++ compiler:
     • gcc on Linux
     • MSVC on Windows
     • clang on macOS

📖 Usage

Below is an example of using ih-lib60870-node to establish an IEC 60870-5-104 connection and handle data:

const { IEC104Client } = require('ih-lib60870-node');
const util = require('util');
const fs = require('fs');

// Initialize an IEC 60870-5-104 client
const client = new IEC104Client((event, data) => {
    if (data.event === 'opened') client.sendStartDT();
    console.log(`Server 1 Event: ${event}, Data: ${util.inspect(data)}`);
    if (data.event === 'activated') client.sendCommands([
        { typeId: 100, ioa: 0, asdu: 1, value: 20 },          // Interrogation command
        { typeId: 45, ioa: 145, value: true, asdu: 1, bselCmd: true, ql: 1 },  // C_SC_NA_1: On
        { typeId: 46, ioa: 4000, value: 1, asdu: 1, bselCmd: 1, ql: 2 },      // C_DC_NA_1: Off
        { typeId: 47, ioa: 147, value: 1, asdu: 1, bselCmd: 1, ql: 0 },       // C_RC_NA_1: Increase
        { typeId: 48, ioa: 148, value: 0.001, asdu: 1, selCmd: 1, ql: 0 },    // C_SE_NA_1: Normalized setpoint
        { typeId: 49, ioa: 149, value: 5000, asdu: 1, bselCmd: 1, ql: 0 },    // C_SE_NB_1: Scaled setpoint
        { typeId: 50, ioa: 150, value: 123.45, asdu: 1 },                     // C_SE_NC_1: Floating point setpoint
    ]);
});

const client2 = new IEC104Client((event, data) => {
    if (data.event === 'opened') client2.sendStartDT();
    console.log(`Server 2 Event: ${event}, Data: ${util.inspect(data)}`);
});

async function main() {
    const sleep = ms => new Promise(resolve => setTimeout(resolve, ms));

    client.connect({
        ip: "192.168.0.1",
        port: 2404,
        clientID: "client1",
        ipReserve: "192.168.0.2",
        reconnectDelay: 2,           // Reconnection delay in seconds
        originatorAddress: 0,
        asduAddress: 1,
        k: 12,
        w: 8,
        t0: 30,
        t1: 15,
        t2: 10,
        t3: 20,
        maxRetries: 5
    });

    client2.connect({
        ip: "192.168.0.10",
        port: 2404,
        clientID: "client2",
        originatorAddress: 1,
        k: 12,
        w: 8,
        t0: 30,
        t1: 15,
        t2: 10,
        t3: 20,
        reconnectDelay: 2,
        maxRetries: 5
    });

    // Wait for synchronization (optional)
    await sleep(1000);
}

main();
