PmNetKey allows to provide the licence to PROMOTIC applications via networks. This way, it is not needed to have licence in own HW-Schlüssel for each individual PROMOTIC application. This licencing procedure can also solve problems of PROMOTIC applications running in virtualized environment, where the PROMOTIC application cannot access the physical HW-Schlüssel connected to USB port. PmNetKey is protected by its own HW-Schlüssel. PmNetKey is typicaly automatically launched on computer boot as a service of the OS Windows.

In order to assure correct functionality it is necessary, that the computers with PROMOTIC applications (licence clients) have network connectivity via the HTTP oder HTTPS protocol to the computer with the PmNetKey program. The communication between PROMOTIC application and the Lizenzserver happens not only when the application is launching, but also after that, periodically (the period is around 1 minute oder or slightly longer). The network connection with the Lizenzserver must be functional during the whole time the PROMOTIC application is running.

The licence on the Lizenzserver are so-called "floating": The PROMOTIC applications can be launched on any PC (connected to the network) but the number of simultaneously running applications can not exceed the number of runtime licence present on the Lizenzserver. Wenn, For example, there are 2 runtime licence present on the Lizenzserver, then it is possible to run 2 applications simultaneously. Additional Applikation (third) can not be launched. Wenn one of the running applications is stopped and thus does not communicate with the Lizenzserver for 10 Minuten, then its licence is released on the Lizenzserver and available to be used by another application. Now it is possible to run the other Applikation - it will use this released licence.

The PROMOTIC application network licence für PmNetKey are provided in der Form of a licence file (siehe Network licence key). The licence file is functional only with the corresponding Lizenzserver, it was generated for. It will not function with another Lizenzserver.

Installation, uninstallation of the Lizenzserver and service configuration

The program has its own installation file, because it is often installed on a computer, where the PROMOTIC system is not present. The installation program can be downloaded from (z.B. PmNetKey XXYYZZ.msi). The program is to be installed on the computer that is going to act as a Lizenzserver. While being installed, the program is configured as service OS Windows with automatic launch on system boot. The PmNetKey service can be configured, stopped and launched by using the standard OS Windows resources (services.msc service manager).
PmNetKey is protected by its own HW-Schlüssel. The program is not functional without the HW-Schlüssel. The HW-Schlüssel must be generated especially for this purpose, normal PROMOTIC application HW-Schlüssel cannot be used in such case. The HW-Schlüssel must be permanently present in the USB port of the computer that is running the PmNetKey.

The program (service) can also be controlled from the command line by entering parameters. The command line window must be launched with the Administrator rights. The commands are relevant in some special cases z.B. in OS Windows *.bat files. Usually it is not necessary to use such commands because the OS Windows service is configured during the program installation process and it is removed when the program is uninstalled. The konfiguration, stopping and launching is provided by using the standard OS Windows resources. Individual commands:
PmNetKey -i - Adds the OS Windows service for the PmNetKey program. The service will be configured in order to launch automatically on system boot. It is done automatically during the program installation.
PmNetKey -u - Removes the OS Windows service of the PmNetKey program. It is done automatically during the program uninstallation.
PmNetKey -s - Launches the OS Windows service of the PmNetKey program.
PmNetKey -k - Stopps the OS Windows service of the PmNetKey program.
PmNetKey - Launches the PmNetKey program as a normal Applikation, not as a service. Application icon appears in the OS Windows Sys Tray among icons on the right. This can be handy for testing purposes.

Lizenzserver konfiguration

The program is configured via the PmNetKey.ini configuration file. This file is created automatically during the installation and is located in the same folder as PmNetKey.exe (the typical location is: C:\Program Files\Promotic oder C:\Program Files (x86)\Promotic).
Beschreibung of the keys in the [Config] section:
WebServer - The key allows to modify the port and protokoll (HTTP oder HTTPS) that will be used for listening by the internal Web server of the PmNetKey program. If not set, then the default value http://+:81/ is used, it means that the HTTP protocol and port 81 are used. The ";" character at the beginning of the line changes it to a comment. Such line is not taken into account.
Beispiel of the PmNetKey.ini configuration file for the HTTP protocol and port 83
Beispiel of the PmNetKey.ini configuration file for the HTTPS protocol and default port 443
LogDir - This key allows change of the default foder where the Log file will be located. If not set, then the Log file is located in the same folder as the PmNetKey.exe program. Be informed that the default installation directory may be read-only.
Beispiel of the PmNetKey.ini configuration file for placing the Log file into the folder C:\Windows\Temp
LogRefresh - This key specifies whether the information regarding client licence refersh is written into the Log file. The 1 value enables writing, The 0 value disables writing. The default logging period is 1 minute for each client. This may be useful for debugging problems with network licences but from long term point of view, periodically logging this information may overwrite other important logs from the circular log file(s). If not set, then the logging of licence client refresh into the Log file is disabled (the 0 value).
Beispiel of the PmNetKey.ini configuration file that enables logging of periodical client licence refresh into the Log file
Medium - This key allows to define the specific HARDWARE key that is used for runtime protection of the PmNetKey Lizenzserver. It may contain a list of HARDWARE keys (separated by comma) that is being evalueated starting from the first entry until the first connected HW Key is found (z.B. hwkey:k1234,hwkey:k1111). If not set, then the default value "hwkey" is used, meaning any HARDWARE key. If the list is not defined and while multiple HARDWARE keys are connected to the computer then after the computer is rebooted the Lizenzserver may get paired with another HW Key.
Beispiel of the PmNetKey.ini configuration file that defines the specific HARDWARE key with number 1234 for the protection of licence server.

Commissioning the HTTPS protocol of the Lizenzserver:

The implementation of the Lizenzserver (Web server) is provided by the OS Windows "HTTP service". The konfiguration of HTTPS protocol is done axactly the same way, as for the HTTPS protocol in the PmaWeb object, d.h. by the utility PmHttpConfig.exe (it is necessary to set the rights, Import the certificate of the server and connect it with the corresponding Web server).

Monitoring the Lizenzserver functionality

The program allows to monitor the current status of provided network licence and also the history of network licence clients logins and logouts. The monitoring is provided via the Web interface. PmNetKey contains an internal Web server, that offers the info.html und log.html pages on it s IP address, protocol and port. For example http://localhost:81/info.html und http://localhost:81/log.html.

Behavior of the PROMOTIC application when the connection with the Lizenzserver is lost

Wenn the periodic communication with the Lizenzserver is permanently failing, then the running PROMOTIC application goes through the following states:
1) information - first, the error message about the failed communication with the Lizenzserver is displayed in global errors. Dhis state is reached after the first failure of the periodical communication. This state lasts around 10 Minuten.
2) warning - after that, the warning window is displayed (repeatedly wenn the user closes it) and in the global errors the communication failure message is displayed. This state lasts around 48 Stunden.
3) error - finally, the situation is evaluated as fatal error, the Applikation is stopped and licence error message is displayed in the global errors.
The states 1) and 2) are immediately terminated after first successfull periodical communication with the Lizenzserver. Wenn the communication with the Lizenzserver fails permanently, then the Applikation is stopped after 48 hours. The method Pm.LicenceInfo(10) for detection of time that has passed since the last successfull communication with the licence server can be used.
If the connection to the Lizenzserver is not functional, the PROMOTIC application cannot be launched. The time interval protection of the application before it is stopped, because of the Lizenzserver communication failure is applied only for application that are allready running.

Commissioning the SWK licence files on the Lizenzserver and the licence client

a) Lizenzserver - The licence file it is necessary to copy into the C:\Program Files\Promotic oder C:\Program Files (x86)\Promotic folder.
b) Licence client - In the application INI file (for runtime - PmRt), oder in PROMOTIC INI file (for the development environment - PmDev und PmDevSchool) (ab Version Pm8.3.0) it is necessary to create the section [Licence] and in this section to create the key Medium as described below (reference to a PmNetKey and to a specific Network licence key):
wo the netkey indicates the network licence, http oder https specifies the protokoll, followed by the IP address oder computer Name, internal Web server port and the licence SWK file Name.

Logged-in Windows user must have the permissions for writing into following files:
