Option Tab
Object Visibility Option	The Visibility Option allows you to show or hide the object based on the value of a Tag.
Tag Name	Select a Tag Name that will control the visibility of the object.
Object is visible when address value is	Click on the down arrow to the right of the field to select the proper operand that makes the value in the field to the right true. When this condition is met, the Object becomes visible. When the Tag Name is discrete, the only options are ON or OFF.
Scaling Option	The Scaling Option allows you to scale the Tag Name value (PLC) to display as a different value. For example, the PLC value range is 0 to 4095, but the desired display value is 0 to 100.
PLC value	Point 1 - enter the minimum PLC value expected; for example, 0. Pinata - enter the maximum PLC value expected; for example, 4095.
Display value	Point 1 - enter the minimum Display value desired; for example, 0. Pinata - enter the maximum Display value desired; for example, 100.
Meter and Background Images	Meter and Background Images allows you to make the Bar Meter look like real Process Equipment, such as a Tank with a level tube.
Image	An image may be added from PC or network storage (disk), Symbol Factory or from the PC Clipboard if an image has been copied there.
Lock Aspect Ratio	Maintains the aspect ratio of the image. This keeps the graphic proportional when changing the size of the object. The Object Frame will change size, but the graphic will stay proportional.
Stretch to Fit	The image will normally be in its original size, which may not fit in the object. Stretch to Fit forces the graphic to stretch or shrink to fit in the Object window.
Set Meter Area	Identify the area of the Meter Image where the Meter will be placed.
Transparent	Use this feature to select the color in the image to make transparent so the screen background is visible. More information is available in the Set Transparent Color Help topic.

Note: Stretch to Fit is a convenient, but uses a large amount of CPU resources. When possible, use a graphics program to render the bitmap to the desired fit and save the bitmap file. Use the revised bitmap file in the object in C-more.
