There are three components that are licensed on the Standalone DeltaV PK controller; the controller itself (by the number of device signal tags); the Engineering Station; and, the local HMI.
The system key defines what the workstation is (either an Engineering Station or a local DeltaV HMI). Additional licenses define what you can do on that workstation (for example, enabling features of the software). Only the workstations require system keys as described here which are attached to the appropriate workstation's USB port.
The DeltaV PK controller is licensed based on the number of device signal tags (DSTs) purchased. You are prevented from downloading more DSTs than the controller is sized for. No other licensing is required. Once commissioned and downloaded, the controller runs independent of any other licenses.
You cannot change a PK controller from one licensed DST amount to another (for example, from a PK100 to a PK300). You must replace the one controller with one that is licensed at the new value.
When the controllers are redundant, both must be replaced and both must have the same DST limit.
The Engineering Station is licensed by the system key that is attached to the Engineering Station. When the Engineering Station is removed, the controller continues to operate having been commissioned and downloaded by the Engineering Station.
There are two classifications of Engineering Station system keys - the Basic and the Professional. Both contain the major version license and, if purchased, the Guardian Support license.
The Basic license does not allow for the Event Chronicle or the Sequence of Events (SOE) Collector on the Engineering Station. Therefore, you must disable the Engineering Station's Alarms and Events subsystem before you can download the Engineering Station.
The SystemID Key Update tool displays the current expiration, the major version, and CSS licenses of the Engineering Station system identifier. Use this tool in conjunction with an update file to extend the expiration or update the Major Version or CSS license. Run the DeltaV PK SystemID Key Update tool on the Engineering Station. It is located in the DeltaV\Bin folder as PKKeyUpdate.exe.
Folder access might require elevated permissions to run this application.
The local HMI is licensed by the system key that is attached to it. This system key remains attached to the HMI station.
There is only one classification of system key for the local HMI - the Standalone HMI (ST).
The standalone system license allows for the Event Chronicle and the Sequence of Events (SOE) Collector on the local DeltaV HMI.
The local HMI licenses (that is, the basic operator station and the multiple monitor licensing) as well as the scale-up licenses are not recognized by a DeltaV balance-of-plant system.
Local HMI licensing is viewed using the Standalone License Manager. This tool (DVSTDiag.exe) is located in the DeltaV\Bin folder (folder access might require elevated permissions to run this application).
