StrictlyEqual

Description:	Will return TRUE if the parameter values are of the same type and also are equivalent, or if both are invalid.
Returns:	Boolean
Usage:	Script or steady state.
Function Groups:	Variable
Related to:	StrictlyNotEqual | IsEqual
Format:	StrictlyEqual(Parm1, Parm2);
Parameters:

Parm1

Required. Any value, to be compared to parameter 2.

Parm2

Required. Any value, to be compared to parameter 1.

Comments:

Will return either True or False. Will never return Invalid.

X	Y	X == Y	X != Y	StrictlyEqual (X, Y)	StrictlyNotEqual (X, Y)
Invalid	Invalid	Invalid	Invalid	TRUE	FALSE
Invalid	1	Invalid	Invalid	FALSE	TRUE
1	Invalid	Invalid	Invalid	FALSE	TRUE
1	1	TRUE	FALSE	TRUE	FALSE
\AS_1	\AnalogStatus	FALSE	TRUE	FALSE	TRUE
\AnalogStatus	\AS_1	TRUE	FALSE	FALSE	TRUE
2	"2"	TRUE	FALSE	FALSE	TRUE
"2"	2	TRUE	FALSE	FALSE	TRUE

Note 1: AS_1 is an object; an instance of the module \AnalogStatus

Note 2: For text to number comparisons, VTScada will attempt to cast the number to text, then perform a case-sensitive comparison. The order of the operands does not matter.

Examples:

Increment NumberOneCount whenever a numeric 1 comes through, and TextOneCount whenever a text "1" comes through.

If Watch(1, Input);
[
  IfThen(StrictlyEqual(Input, 1),
     NumberOneCount++;
  );
  IfThen(StrictlyEqual(Input, "1"),
    TextOneCount++;
  );
]
