Usage

$AccessLevel

Remarks

The value for this tag is determined by the access level assigned to the currently logged-in user's security profile within the InTouch HMI. This profile can be accessed using the Configure Users menu in WindowViewer.

The actual numeric value of $AccessLevel has no meaning to WindowViewer, except that a value of 9000 or greater indicates administrative privileges and enables the Security menu within WindowViewer. Use the $AccessLevel system tag to further customize security within the system.

Data Type

Integer (read only)

Valid Values

0 through 9999

Example(s)

The following statement is used for the visibility link to make an object, such as a button, visible based on the logged on user's access level:

$AccessLevel >= 2000;
{Objects can have a "disable" link associated with them, with the expression based on $AccessLevel.}
$AccessLevel < 5411;

IF $AccessLevel <=500 THEN

Show "Access Denied"; {popup window denying access}

ELSE

Show "Access Granted"; {popup window granting access}

ENDIF;
