Explanation

ULIDLib provides ULID generation FB, but please keep the following in mind.

1. Uses built-in Rand instruction for random number generation
   An unseeded Rand instruction is used to generate random numbers, but the Rand instruction is most likely not a CSPRNG.

Generating ULID

CASE iState OF
  0:		
    iULIDGen(Execute:=TRUE,
             // Japan
             UtcOffset:=TIME#+9h,
             // 1733800332500ms
             Timestamp:=DT#2024-12-10-12:12:12.500_000_000,
             // 01JEQ8V36Mxxxxxxxxxxxxxxxx
             Out=>iULID);

    Inc(iState);
END_CASE;
