Entering a Symbol in a Picture

When you enter a symbol in a picture, you must type an at sign (@) at the beginning and end of the symbol name. This allows the iFIX software to differentiate tag group symbols from ordinary text.

NOTE: When defining symbols in the Symbol column of the Tag Group Editor, you only need to enter the symbol name, not the @ signs.

Example

You want to enter a data link in a picture that displays the value of a temperature output block. You will use this picture three times to show three similar processes. To use a symbol called Temperature in the picture, enter the following for the data link:

@Temperature@

When the iFIX software reads text in this format, it identifies the text as a tag group symbol. When a picture opens, or a new picture replaces the current one, the symbol is replaced with the assigned substitution.

In the Symbol column of the Tag Group Editor you would enter:

Temperature
