Data type examples

This table lists examples of data types.
Situation
Example
General data type with three members, one hidden. 
struct SampleDT {
  dint Sample_DINT_Member {
 
    desc := “this is a DINT member of the UDT”;
 
  }
 
  hidden sint hiddenHostMem;
 
  bool Sample_BOOL_Member0 := hiddenHostMem.0 {
 
    desc := “This is a BOOL member of the UDT”;
 
  }
 
  bool Sample_BOOL_Member2 := hiddenHostMem.1;
 
}
Struct declaration: an array member and a hidden member are declared. Some properties are defined for both.
struct MyDT {
  desc := “My favorite data type”;
 
  dint[10] mem1;
 
    
  timer mem2;
 
  bool myBitMember;
 
}
TIP:
Use double quotes for descriptions (desc).
