<-- AWP_In_Variable Name='SERVER:current_user_id'

Use='"Data_Block_10".server_user' -->

"server_user" in data block "Data_Block_10".

<-- AWP_Out_Variable Name='Weight'

Use='"Data_Block_10".Tank_data.Weight' -->

In this example, the value in data block structure member Data_Block_10.Tank_data.Weight

can be referenced simply by "Weight" throughout the rest of the user-defined Web page.

<-- AWP_Out_Variable Name='Weight' Use='"Raw_Milk_Tank_Weight"' -->

In this example, the value in the PLC tag "Raw_Milk_Tank_Weight" can be referenced simply

by "Weight" throughout the rest of the user-defined Web page.

If a tag name or data block name includes special characters, you must use additional

quotation marks or escape characters as described in the topic Handling tag names that

contain special characters (Page 1055).

Defining enum types

You can define enum types in your user-defined pages and assign the elements in an AWP

<!-- AWP_Enum_Def Name='<Enum type name>' Values='<Value>,

Note that the entire string of enum value assignments is enclosed in single quotation marks,

and each individual enum type element assignment is enclosed in double quotation marks.

The scope of an enum type definition is global for the user-defined Web pages. If you have

set up your user-defined Web pages in language folders (Page 1074), the enum type

definition is global for all pages in the language folder.

<!-- AWP_Enum_Def Name='AlarmEnum' Values='0:"No alarms", 1:"Tank is

full", 2:"Tank is empty"' -->

Name of the enumerated type, enclosed in single or double quotation marks.

The constant indicates the numerical value for the enum type assignment. The total

number is unbounded.

The name is the value assigned to the enum element.
