6 Introduction

just re-name the sample DLL file LicenseSecurity.dll; however, you are solely responsible for the

creation of the security DLL file.

You also need to modify your FPM application so that it can check whether a customer’s SmartServer

has a valid FPM license file for running your FPM. This entails writing a separate license validation

routine in your FPM application that (1) checks whether the Lock ID (MACID, LUID, or other user-

defined lock type) specified in the FPM license file matches the one on the customer’s SmartServer,

and (2) checks whether the license key in the FPM license file is valid.

Once you have created the security DLL and license generator configuration files and you have

enabled license validation in your FPM application, you can use the i.LON License Generator user

interface to create FPM application licenses. The FPM application license is an XML file that must be

on a SmartServer in order for it to run your licensed FPM. This means that you can make your FPMs

available to customers, while protecting your FPMs from unauthorized use or piracy.

A customer who orders a licensed FPM application from you must install the FPM application license

for that FPM on their SmartServer. If a customer attempts to run your FPM application without

installing the FPM license file on their SmartServer, the SmartServer will report a license error and the

FPM will not run on the SmartServer. This means that a customer running one of your FPMs must

have two licenses installed on their SmartServer: an FPM programming license from Echelon and the

FPM application license from your company that you generated for that FPM.

See Chapter 7,

Creating FPM Application Licenses, for more information on creating FPM licenses

and enabling license validation in your FPM application.

Quick-Start FPM Exercise

The following section describes how to create a simple FPM application called UFPTMath and then

deploy, test, and connect the FPM on your SmartServer. The Math application adds two SNVT_count

input data points and stores the result in a SNVT_count output data point. To create, deploy, test, and

connect the Math FPM application, you perform the following steps:

1. With the NodeBuilder Resource Editor, create a user-defined functional profile template (UFPT)

for the FPM, and then generate your company’s FPM resource file set. Copy your company’s

updated FPM resource file set to the root/lonWorks/types/User/<YourCompany> folder on the

SmartServer flash disk.

2. With a text editor such as Notepad, create a model file (.nc extension) in which you declare all the

data points in the UFPT, and a functional block that implements an instance of the UFPT. With

the i.LON SmartServer 2.0 LonWorks Interface Developer tool, generate a device interface (XI F)

file from your model file. Copy the XIF to the root/lonWorks/Import/<YourCompany> folder on

the SmartServer flash disk.

3. With the i.LON SmartServer 2.0 Programming Tool, create a new FPM project from the UFPT

you created in step 1.

4. With the i.LON SmartServer 2.0 Programming Tool, write the FPM application and then build it.

Note: The full version of the i.LON SmartServer 2.0 Programming Tools must be installed on

your computer to build the FPM.

5. On your SmartServer, deploy the FPM. To do this you upload the FPM application to the

root/modules/User/<YourCompany>folder on the SmartServer flash disk. You then add a new

internal device to the SmartServer that uses the device interface (XIF) file that you created for the

FPM.

6. On your SmartServer, test the FPM. To do this, you open the View – Data Points Web page, add

the input and output data points in the FPM application, update one of the input data points, and

observe that the output data point is updated accordingly.
