This Quick Start Guide will help you:

Setup your LDM Development Environment

Build a sample ThingWorx application program

Run the ThingWorx application program

1.1 Introduction

The ThingWorx-LDM-interface-lib is a software library (available for free at

www.prosoft-technology.com), to be used with a ThingWorx C SDK software

library from PTC®. You can use these to create a sample application to allow

communications between a ControlLogix PLC and a ThingWorx Server.

The sample application can be used as-is. This document will provide step-by-

step instructions on how to create the sample application. You can also extend

the features of the sample application to suit your needs.

Our goal is to read and write data from the PLC to and from ThingWorx. This will

be accomplished by running the sample application on the MVI56E-LDM,

connected to the ThingWorks Server.

Start Here MVI56E-LDM ♦ ControlLogix Platform

Quick Start Guide ThingWorx® Add-On

Page 6 of 49 ProSoft Technology, Inc.

The Quick Start Guide provides the steps to install the software onto a Windows

10 PC, build the sample application, and load it on the MVI56E-LDM. You will

then configure it with a working sample.

1.2 Development Environment

The MVI56E-LDM development tools run in Linux. If you have experience with a

previous ProSoft Technology LDM module, you may have setup a Linux Debian

6 Virtual Machine. The ThingWorx C library SDK will not compile on Debian 6, so

this guide will step you through using a Docker® container on a Windows 10 PC.

2 Prerequisites

2.1 MVI56E-LDM-TW .zip file

Navigate to the MVI56E-LDM product page at www.prosoft-technology.com, and

download the zip file MVI56E-LDM-TW-xxx.zip (where xxx is version number).

On your PC, create a folder C:\Workspace. Save and unzip this file in this folder.

The interface library contains the following components:

2.2 Source Code for the ThingWorx Edge C SDK

1 Download the C-SDK (c-sdk-2-2-1-1321.zip) file for the ThingWorx

Platform from the PTC MarketplaceTM:

https://marketplace.ptc.com/apps/193540/c-sdk#!overview.

Note: At the time of this writing, the C-SDK version was 2.2.1.1321.

2 Create a C:\Workspace folder on your PC, and copy the .zip file into it,

and unzip it. It will be unzipped into a folder c-sdk-2.2.1.1321-master.

Rename it to ThingWorx-edge-c-sdk.

3 You should now have C:\Workspace with these folders:
