The PROMOTIC system licences can be ordered on various carriers.
The main advantage of this licence carrier is its mobility – the user can move this licence key as needed from one PC to another.
The PROMOTIC application can access the licences on this carrier either directly (default setting), or via the local PmLicServer licence server (advisable solution for RDP access see PROMOTIC system and Windows remote desktop (RDP)).
This carrier can be used in situations where standard hardware key cannot be used - for example when using virtual computers with no access to USB ports see PROMOTIC system and virtual computers.
The PROMOTIC application can access this type of licence carrier only via the local PmLicServer licence server.
This carrier type is used in situations, where the standard HW Key cannot be used.
The PmLicServer service can be running on any computer that is accessible (for other computers) in the network and has one free USB port. This USB port is necessary for connecting a hardware key (that contains no licences) that is used for licencing the licence server. One licence server can provide multiple PROMOTIC licences via the network.
The PROMOTIC application can access this type of licence carrier only via the network PmLicServer licence server.
The licence carrier setting for the application is done in the application INI file see Description of keys in the [Licence] section. For easier access to the configuration use the "PROMOTIC settings" configuration window, see Settings of the list of PROMOTIC licence carriers.
The PROMOTIC application periodically checks whether the licence carrier is available. This is valid for all licence carrier types and all access methods.
If the connection of the application with the licence is interrupted then a countdown starts. During this countdown, the application is still running, but indicates licence connection loss, see Behavior of the PROMOTIC application when the connection with the licence server is lost.
If this licencing method is used then the PROMOTIC applications do not need to use the standard HW Keys, but they can obtain the licence by means of Ethernet communication with the "PmLicServer" server.
This is very handy if the applications are running in virtual environment, or if there is a large number of licences used in the enterprise.
