Programming Example

The data types of EQ_In1, EQ_In2 and EQ_In3 are INT, UINT and DINT respectively and the
data type of Out1 is BOOL.
Out1 changes to TRUE when the values of EQ_In1, EQ_In2 and EQ_In3 are 50, 50 and 50
respectively and EQ_EN changes to TRUE as shown in Variable 1.
Out1 changes to FALSE when the values of EQ_In1, EQ_In2 and EQ_In3 are 10, 50 and 100
respectively and EQ_EN changes to TRUE as shown in Variable 2.


The data types of EQ_In1 and EQ_In2 are both TIME and the data type of Out1 is BOOL.
Out1 changes to TRUE when the values of EQ_In1 and EQ_In2 are T#50ms and T#50ms
respectively and EQ_EN changes to TRUE.
