Licensing

This page explains the licensing of the Fanuc SDK: the 30 day trial, the license key, the license states and the maintenance. The SDK is a commercial product. Every feature is available during the trial.

Trial period

The trial starts the first time the library is used on a machine and lasts 30 days. Nothing has to be registered, and no feature is disabled during the trial.

FanucRobot.LicenseInfo gives the current state. EvaluationDaysLeft is the number of days left, and becomes negative when the trial has expired.

Register a license

RegisterLicense

Buy a license (see pricing): you receive a license key and the name of your organization (the licensee). Pass both to the static method RegisterLicense of FanucRobot, once, before the first connection.

static void Main()
{
// Register the license once, before the first connection
FanucRobot.RegisterLicense("YourCompanyName", "YOUR_LICENSE_KEY");

LicenseInfo info = FanucRobot.LicenseInfo;

// Number of trial days remaining
int? evaluationDaysLeft = info.EvaluationDaysLeft;

bool licenseValid = info.State == LicenseState.Licensed;

// A readable description of the current state
Console.WriteLine(info);


// Check the license once at startup, rather than catching the exception
// on every connection
if (!FanucRobot.LicenseInfo.IsLicensed)
{
    Console.WriteLine(FanucRobot.LicenseInfo);
    return;
}
}
}

The registration is static: it applies to the whole application, not to one FanucRobot. You can register a key after the end of the trial.

LicenseInfo.ToString() gives a readable description of the state. It is the message of an InvalidLicenseException.

License states

IsLicensed is true for Licensed, Trial and ExtraTrial.

Maintenance

A license includes a number of maintenance years. MaintenanceExpirationDate is the last date of the releases that the key can use. A release published after this date reports MaintenanceNeeded. The releases you already use keep working: a new key is only needed to use a newer release.

Without a valid license

Connect checks the license before it opens the connection. Without a valid license, it throws an InvalidLicenseException. The message says why, and the LicenseInfo property of the exception gives the full state.

Test IsLicensed once at startup, as in the code above, rather than catching the exception at each connection.

The offline features (kinematics, motion planner, file parsers) do not connect to a controller.

Source license

The Standard and Pro licenses deliver the obfuscated DLL. The Source license also delivers the full C# code of the library and its Visual Studio solution, to change and build it yourself, within the limits of the license agreement.

Try it in the demo application

Everything on this page can be tried without writing code, in the License page of the demo application.

The demo application is open source. The C# source of this page is LicenseControl.cs.
