
When the data types of input variables are not BOOL, TIME, DATE, TOD or STRING, the input
parameters In1~InN are allowed to be the variables of different data types.

When the data types of input variables are one of BOOL, TIME, DATE, TOD and STRING, all the
input variables and output variable should be of the data type. For example, if the data type of In1 is
TIME, the data type of In2~InN must be TIME. Otherwise, an error will occur during the compiling of
the software.
 Precautions for Correct Use

The input variables are not allowed to omit. An error will occur during the compiling of the software if
the input variables are omitted. But the output variable is allowed to omit.

The length of the data type of the output variable must contain the length of all input parameters.
Otherwise, an error will occur during the compiling of the software

Programming Example

The data types of MAX_In1, MAX_In2 and MAX_In3 are INT, UINT and DINT respectively. The data
type of Out1 is DINT. If the values of MAX_In1, MAX_In2 and MAX_In3 are -10, 50 and 100
respectively, the value of Out1 is 100 when MAX_EN is TRUE.


The data types of MAX_In1 and MAX_In2 are TIME. The data type of Out1 is TIME.
If the values of MAX_In1 and MAX_In2 are T#1ms and T#50ms respectively, the value of Out1 is
T#50ms when MAX_EN is TRUE.
