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 GE_In1, GE_In2 and GE_In3 are INT, UINT and DINT respectively and the
data type of Out1 is BOOL.
Out1 changes to TRUE when the values of GE_In1, GE_In2 and GE_In3 are 100, 50 and 50
respectively and GE_EN changes to TRUE as shown in Variable 1.
Out1 changes to FALSE when the values of GE_In1, GE_In2 and GE_In3 are 10, 10 and 100
respectively and GE_EN changes to TRUE as shown in Variable 2.

Variable 1
Variable name Data type Current value
GE_EN BOOL TRUE
GE_In1 INT 100
GE_In2 UINT 50
GE_In3 DINT 50
Out1 BOOL TRUE

Variable 2
Variable name Data type Current value
GE_EN BOOL TRUE
GE_In1 INT 10
GE_In2 UINT 10
GE_In3 DINT 100
Out1 BOOL FALSE

The program

The data types of GE_In1 and GE_In2 are both TIME and the data type of Out1 is BOOL.
Out1 changes to TRUE when the values of GE_In1 and GE_In2 are T#100ms and T#50ms
respectively and GE_EN changes to TRUE.
