Access to variable setting is made in one of three variable setting screens: Local, Module, or Global Variable Settings. To access the Global Variable Settings, right-click on the hardware interface face and select Global Variable Settings. For multi-processor products like Chameleon, right-clicking on any device in the node and selecting Global Variable Settings will result in the same dialog. To access the Module Variable Settings, right-click on the hardware interface face and select Module Variable Settings. To access the Local Variable Settings, right-click on white space in a schema and select Local Variable Settings. Figure 5.7 shows an example (Module) Variable Settings dialog.

The Initial Value may be set to a specific number or state. This value is used when the controller starts from power up or the Schema is instructed to reset on download.
Browse Access describes the usage of each variable within an HMI.
Update to Flash specifies whether the variable value should be saved in FLASH. If the update is set for 'On Command' then the variable is written to FLASH when the Flash Write operator commands. If the update is set for 'On Command and Power Loss' then the variable is written to FLASH when either power is lost or commanded by the Flash Write operator.
Merge Behavior describes how the variable is to be treated when a schema is downloaded using the continue schemas (merge mode) option.
The Access Level column specifies whether the variable initial value can be change in Schema Viewer without a password (Operator Level) or if a password is required (Engineering Level) Schema Viewer Users column indicates the Security Role that has the right to change the initial value of the variable in Schema Viewer. If a Security User is logged in to Schema Viewer (or there is no one logged in) who does have this Role then they will not be able to set the initial value. If the User logged to Schema Viewer in is a member of this Role, then they can change the initial value.
Scope Note comments for the variable are displayed when hovering over that particular variable and in this table.
Labels for Boolean variables' values are displayed in the schema during simulations. These labels may be made more meaningful in the Low and High Label cells.
