You can compare an element of a UDT with a value, but you can't compare whole UDT's.

depending on type of PLC
In Codesys not possible, as a structure is stored differently from a simple VAR.
However you can compare a complete structure, like
var1 EQ var2 (both having same structure)

You have to create your own user defined function for your user defined data type.
