About License Server
Use the License Server feature to manage multiple IWS licenses and serve them over your network. The licenses are loaded onto a single hardkey, and then that hardkey is connected to a network server running the required license management software.
What do I need to use the License Server feature?
At this time, the License Server feature only works with USB hardkeys supplied by Wibu Systems (www.wibu.com). That is because the License Server feature is built on Wibu Systems’ CodeMeter Runtime software, which provides the necessary hardkey drivers, license management, and client-server communication framework.
To make sure that you have the correct hardkey type and license settings, please contact your InduSoft Web Studio software vendor.
The CodeMeter Runtime software is automatically installed with InduSoft Web Studio. Every computer, both client and server, must have it in order to take advantage of the License Server feature. If you want to set up another computer — one on which InduSoft Web Studio has not been installed — as your license server, you must manually download and install the CodeMeter Runtime software.
What designates a computer as a license server is whether the option Run Network Server is selected in the CodeMeter Runtime software settings.
How does the License Server feature work?
First, a computer on the network is set up to be the license server. The computer may or may not also have InduSoft Web Studio installed and licensed. For example, it is often convenient to have your project development workstation and license server be the same computer, so that you can both send projects to target stations and manage the licenses for those stations, but it is not necessary.
Setting up the license server is simply a matter of making sure the CodeMeter Runtime software is installed, connecting the Wibu-type USB hardkey that contains the licenses, confirming that the license settings are correct, and then selecting the option Run Network Server in the CodeMeter Runtime software settings. For more information, see Configure CodeMeter Runtime to serve licenses.
Then, on every other computer that will get its license from the license server, InduSoft Web Studio‘s Protection Manager is used to enable the License Server feature and then connect to the license server. Doing so overrides the normal hardkey license settings on that computer. For more information, see Configure Protection Manager to get license.
What if the server connection is lost?
If, for whatever reason, InduSoft Web Studio loses its connection to the license server, it will continue operating as previously licensed for a grace period of up to 60 minutes.
Dim remainingGracePeriod remainingGracePeriod = $GetLicenseGracePeriod() If (remainingGracePeriod = -1) Then MsgBox "License OK" Else MsgBox "Running on Grace Period! [" + remainingGracePeriod + "] minute(s) remaining" End If
When a user clicks/taps the button during run time, the license is checked and an appropriate message is displayed.
If the grace period expires and InduSoft Web Studio has not either reestablished its connection to the license server or received another license, the program switches to Demo Mode. For more information, see Execution modes.
Please note that when InduSoft Web Studio does reestablish its connection to the license server, the grace period does not immediately reset to the full 60 minutes. Instead, InduSoft Web Studio must remain connected to the license server for at least twice as long as the connection was lost. So, for example, if the connection was lost for 38 minutes, InduSoft Web Studio must remain connected for 76 minutes. After that time, the grace period is reset.
