Control Tags Example

In the following example, a screen control tag is used to display
caution and operator information screens. The controller writes a
screen number to the PanelView whenever operating parameters
exceed predefined limits. The PanelView is configured with the
following screen and control tag information:

Screen Number Tag:

Tag Name = Screen
Tag Address = N7:10

Screen 10:

Configured as Information Screen

Screen 11:

Configured as Caution Screen

The Controller monitors an automatic sorting process. A bar
code reader signals the presence of a package requiring an
operator’s attention. The controller logic program writes a
value of 10 to address N7:10.

Value 10 to N7:10

The PanelView reads the value (10) at the Screen
tag (N7:10). Screen number 10 is displayed.

Screen 10 displayed.
