Changing parameters through HMI Sample Clauses

Changing parameters through HMI. The parameters can be changed at any moment during the system execution by HMI’s Interface. First of all the HMI must query the WP7 Data Provider in order to retrieve the last cost function parameters stored at it. This query must be done for every WP the HMI wants to manage. For each WP two scenarios are possible:  The architecture does not have any previously stored values, and send a “not found” response. This happens if the module had never run before. In this case the HMI interface for managing parameters for that specific WP will not be ena- bled.  The architecture has a set of parameters for that specific WP and gives them to HMI in the response. On the base of the response the HMI creates the interface to manage the parameters for the specific WP (Fel! Hittar inte refer- enskälla.). Once retrieved the parameters for a WP, using the HMI interface, a user can change the parameters’ value. After confirming the change the HMI fires a CFParameter- sChange event (3.3.2.1). The events, requests and responses involved in this process are described in detail in the next four paragraphs.
