Ctrlx-datalayer NPM

Bosch Rexroth ctrlX Data Layer Node.js API

This is the ctrlX Data Layer API for Node.js.

Based on Node.js N-API accessed by module node-addon-api

https://github.com/nodejs/node-addon-api

nan: C++-based abstraction between Node and direct V8 APIs.
Node-API: C-based API guaranteeing ABI stability across different node versions as well as JavaScript engines. (Node-API was previously known as N-API.)
node-addon-api: header-only C++ wrapper classes which simplify the use of the C-based Node-API.

This also uses Node.js native addon build tool node-gyp as native compiler toolchain

The API project has been initially generated by generator-napi-module

https://www.npmjs.com/package/generator-napi-module

Usage

Quick Overview

This library enables read and write access to the ctrlX Data Layer of ctrlX AUTOMATION devices from Bosch Rexroth. It provides interfaces and classes written in Typescript to create ctrlX Data Layer clients and providers.

Install

npm install ctrlx-datalayer --save

Usage

The following code snippet demonstrates how to create a client and read a value from a ctrlX Data Layer node:

async function main() {

    // Create DatalayerSystem and start
    const system = new DatalayerSystem('');
    await system.start(false);

    // Build remote
    const cred = {
        user: 'boschrexroth',
        password: 'boschrexroth',
        ip: '192.168.1.1'
    };
    let remote = Remote.build(cred);

    // Create a client
    const client = await system.createClient(remote);

    // Read value
    const variant = await client.read('framework/metrics/system/cpu-utilisation-percent');
    console.log(variant);
}

main();
