IRREVERSIBLE OPERATING SYSTEM DAMAGE OR DATA CORRUPTION

Before making any changes, back up your Windows Registry in a network folder or other remote location.

Failure to follow these instructions can result in irreparable damage to the operating system of the computer and all existing data.

NOTE: Registry edits must be performed only by qualified and experienced personnel.

The registry keys are in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Schneider Electric\Power Monitoring Expert\2024\WebReach.

The following table lists the default Diagrams registry entries and settings.

Default Entries	Default Settings	Description
AutoDiagramTimeout	20000 milliseconds	Timeout period for the autodiagram components to communicate with the device and determine the appropriate template to open.
ExpireTimeLimit	600 seconds	Time limit for a diagram subscription to update its timestamp. If the subscription is not updated within this time period, it is considered expired and is removed.
HTTPRefreshInterval	10 seconds	The web page refresh rate.
SubscriptionObject	pmlitem:webreachstore:	The name (tag) that the subscription service uses to find Diagrams-related information.
VirtualDirectory	ION	The part of the Web address that points to the Diagrams-generated Vista diagrams for displaying in the browser.
XMLRefreshInterval	3000 milliseconds	The real time data update rate on the web page.

The following table lists the optional registry entries you can set for custom functionality. Modifying system registry keys without the required knowledge or experience in these procedures can damage the computer's operating system and all existing data.

Optional Entries	Default Settings	Description
NetworkDiagram	x-pml:/diagrams/ud/ network.dgm	This value specifies the network diagram to display as the homepage for Diagrams. The value can be a relative path, such as the default setting, or it can be an absolute file path (e.g.: D:\customdiagrams\ud\networkB.dgm).
QueryTimeout	See description.	This value determines how long Diagrams waits for the results of a query to return from the database before timing out. If this registry entry is not created or no QueryTimeout value is specified, Diagrams times out after 60 seconds.
QueryTimeout	See description.	This optional registry entry is useful if you know that a query will take more than 60 seconds to return its results and you do not want Diagrams to time out before then. Specify a value that gives you enough time to get your query results.
