plcnext

A node package for use with PLCnext Technology controllers from Phoenix Contact.

Code Example

var plcnext = require("plcnext");

// Create program templates.
var nodeTemplateArray = plcnext.getPrograms("/opt/plcnext/projects/PCWE/Plc/Meta/PCWE.meta.config");

// Create the set of program instances.
var nodeProgramArray = plcnext.getProgramInstances("/opt/plcnext/projects/PCWE/Plc/Plm/PCWE.acf.config", "/opt/plcnext/projects/PCWE/Plc/Esm/PCWE.esm.config");

// Create connections between programs.
var linkDataArray = plcnext.getConnections("/opt/plcnext/projects/PCWE/Plc/Gds/PCWE.gds.config");

// Write program connections back to the PLC.
plcnext.setConnections(linkDataArray, "/opt/plcnext/projects/PCWE/Plc/Gds/PCWE.gds.config")
  

Motivation

This package includes functions for reading and writing information from PLCnext configuration files.
These functions can be used to build node applications that run directly on the PLCnext platform.

Installation

npm install plcnext
