Example of how to use when reading a tag
<!-- AWP_Enum_Def Name='AlarmEnum' Values='0:"No Alarm", 1:"Vessel
is full", 2:"Vessel is empty"' -->
<!-- AWP_Enum_Ref Name='"Alarm"' Enum="AlarmEnum" -->
...
<p> The current value of "Alarm" is :="Alarm": </p>
If the value of "Alarm" in the CPU is 2, the HTML page shows 'The current value of "Alarm" is
container is empty' because the definition of the enum type assigns the numerical value 2 to
the character sequence "Container is empty".

The value 1 is written to the PLC tag "Alarm" because the definition of the enum type
assigns the numerical value 1 the text "Container is full".
Note that the name specified in "AWP_In_Variable" must be exactly the same as the name
specified in "AWP_Enum_Ref".
