Programming Example

The data types of LT_In1, LT_In2 and LT_In3 are INT, UINT and DINT respectively and the
data type of Out1 is BOOL.
Out1 changes to TRUE when the values of LT_In1, LT_In2 and LT_In3 are -10, 50 and 100
respectively and LT_EN changes to TRUE as shown in Variable 1.
Out1 changes to FALSE when the values of LT_In1, LT_In2 and LT_In3 are 20, 10 and 100
respectively and LT_EN changes to TRUE as shown in Variable 2.
