9.4.4.2. Point Reference Information

Information about the point that does not change over time, but is generally fixed over the life of the point.

It can be useful when specific information about the point is needed that may not be known until run time.

These parameters follow the same format as Point Status Information with a few exceptions. The information

is known immediately when the page loads, and does not change over time. The data is also not hookable as it

is for Point Status Information.

Table 9-5 displays Point Reference Information Parameter Symbols:

Parameter Symbol Definition

${ 0.id} The database point ID. This is a number and is generally only useful for diagnostic pur-

poses.

${0.path} The path of point. It is a / (forward slash) separated list of names from where the page is

loaded up to the point. For a screen at the Application Instance level this will be the same

as the point name. For a screen at the application type level it will be the Application In-

stance name with the slash followed by the point name, etc.

${0.name} The display name of the point reference as shown in the tree or context menu title.

${0.resolved} True if the point was successfully resolved. “Resolved” in this sense means “found in the

database.” A point that wasn’t successfully resolved when the screen was loaded may

cause the widget to be invisible at run time.

${0.visible} True if the point is visible.

${0.dataType} A numeric code indicating the type of point (0=undefined/unknown 1=analog 2=digital

3=system list). Note that the ${0.type} property can be used to display an interpretation

of these numbers.

${0.eu} The Engineering Units short abbreviated form. For example oF (for Degrees Fahrenheit).

Note that for digital points, it will contain the ON Engineering Unit with a slash followed

by the OFF Engineering Unit.

${0.engUnits} The Engineering Units long non-abbreviated form. For example Degrees Fahrenheit.

Note that for digital points, it will contain the ON Engineering Unit with a slash followed

by the OFF Engineering Unit.

${0.logDataAvailable} This can be TRUE or FALSE. TRUE indicates that there is log data in the database.

FALSE indicates that there is no log data in the database. This is different from ${0.lo-

gAvailable}, which simply indicates that there is a log in the device but that there may

not necessarily be any log data actually retrieved into the database for this point.

${0.logAvailable} If this point has a log available, then it is TRUE.

${0.nativeControllerInfo} Special parameter corresponding to a point property used for screens running in E2 sys-

tems. This is not generally useful for an Application screen.

${0.appsInstName} The name of the application instance this point is in.

${0.appsTypeName} The name of the application this point is in.

${0.unittName} The name of the unit this point is in.

${0.csName} The name of the control system this point is in.
