The format for entering default values for integer, real, bit, string, time, and date and time variables is:
VAR
<Value name> : <data type> := <default value>;
END_VAR
Example:
The following example shows how default values can be set for a variety of built-in data types:
VAR
a: INT:= 535;
d: DATE:= D#2004-06-21;
t: TIME_OF_DAY:= TOD#12:30:07;
n: TIME:= T#1h30m;
p: ARRAY[1..4] OF INT:= [10,90,12,14];
q: ARRAY[1..100] OF REAL:= [100(20.5)];
END_VAR;
The default value for the q variable sets 100 array values to have a default value of 20.5.
