is a relative or absolute reference to the tag that stores the result of the expression. The tag name can include an area name.<expression>
is a value, string, tag name, or a more complex expression.Remarks
This command is run locally on the HMI server,
FactoryTalk View SE
Client, or FactoryTalk View Studio
that issued it.When using the command:
- Do not nest brackets.
- Do not use brackets around tags to the left of the equal sign.
- Enclose strings in quotes. A string can contain any character and spaces.
- Enclose tag names that contain dashes or begin with a number, in curly brackets{ }when you use them in an expression. This distinguishes the characters in the tag name from the characters in an expression.
- Do not include the equal character (=) in the tag address because it is the command's reserved character.
