Precautions for Correct Use

The input variables are not allowed to omit. An error will occur during the compiling of the software if
any input variable is omitted. But the output variable is allowed to omit.

The data type of output variables must be BOOL. Otherwise, an error will occur during the compiling
of the software.

Programming Example

The data types of GT_In1, GT_In2 and GT_In3 are INT, UINT and DINT respectively and the
data type of Out1 is BOOL.
Out1 changes to TRUE when the values of GT_In1, GT_In2 and GT_In3 are 100, 50 and 10
respectively and GT_EN changes to TRUE as shown in Variable 1.
Out1 changes to FALSE when the values of GT_In1, GT_In2 and GT_In3 are 20, 10 and 100
respectively and GT_EN changes to TRUE as shown in Variable 2.

The Program

The data types of GT_In1 and GT_In2 are both TIME and the data type of Out1 is BOOL.
Out1 changes to TRUE when the values of GT_In1 and GT_In2 are T#100ms and T#50ms
respectively and GT_EN changes to TRUE.
