Making run-time changes in FactoryTalk applications

Changes made to the development environment that can be transferred to the application while it is running are commonly called runtime edits.
Runtime edits fall into four groups:
  • Edits that take effect immediately
  • Edits that require a non-disruptive action, such as reopening a graphic display, before they take effect
  • Edits that require a disruptive action, such as restarting a server or a runtime client, before they take effect
  • Edits that cause adverse effects immediately
Edits that may cause adverse effects include the following:
  • Editing the name of a computer, hosting a
    FactoryTalk Linx
     or OPC server
  • Editing the redundancy properties of a
    FactoryTalk Linx
     server
  • Deleting a server (OPC,
    FactoryTalk Linx
    , or HMI)
  • Deleting an area
  • Modifying
    FactoryTalk Linx
     shortcut information
  • Modifying the contents of the
    FactoryTalk Linx
     Communications tab
  • Disabling
    FactoryTalk Alarms and Events
     support while a
    FactoryTalk View SE
     Display Client is running and displaying
    FactoryTalk Alarms and Events
     information
FactoryTalk
 warnings will alert you when you make an edit in the development environment that adversely affects the runtime system.
If the change is made through a dialog box, this warning icon Warning icon appears next to the component where the edit can be made. Hovering the cursor over the icon shows the following warning message: "Modifying this data at run time could cause unexpected results."
If the edit is made through a menu item, a warning message shows when you click the menu item.
When you see this icon or warning message, it indicates that if the change is made while the application is running, it will have one or more of the following adverse effects:
  • One or more of the runtime clients (for example, the
    FactoryTalk View SE
     Display Client) may become unresponsive (for example, does not respond to mouse input).
  • One or more of the runtime clients may stop showing correct data (for example, a changing tag value is not reflected in the client).
  • One or more of the
    FactoryTalk View
     processes fail or stop responding.
