Thanks.
I'll try it.

What about this?

TYPE TIMESTAMP_UNION :
UNION
    As2RealS:       TIMESTAMPASREAL;
    AsTimeStamp:    TIMESTAMP;
    AsHex:          TIMESTAMPASHEX;
END_UNION
END_TYPE

TYPE TIMESTAMPASREAL :
STRUCT
    Real1:      REAL;
    Real2:      REAL;
END_STRUCT
END_TYPE

TYPE TIMESTAMPASHEX :
STRUCT
    {attribute 'displaymode':='hex'}Byte1:      BYTE;
    {attribute 'displaymode':='hex'}Byte2:      BYTE;
    {attribute 'displaymode':='hex'}Byte3:      BYTE;
    {attribute 'displaymode':='hex'}Byte4:      BYTE;
    {attribute 'displaymode':='hex'}Byte5:      BYTE;
    {attribute 'displaymode':='hex'}Byte6:      BYTE;
    {attribute 'displaymode':='hex'}Byte7:      BYTE;
    {attribute 'displaymode':='hex'}Byte8:      BYTE;
END_STRUCT
END_TYPE

TYPE TIMESTAMP :
STRUCT
    Hour:       USINT;  
    Year:       USINT;
    Month:      USINT;  
    Day:        USINT;
    mSec:       UINT;   
    Second:     USINT;  
    Minute:     USINT;
END_STRUCT
END_TYPE

PROGRAM Test_PRG
VAR
    TestTimestamp:      TIMESTAMP_UNION:= (As2Reals:= ( 
        Real1:= 4.14855132E-28,
        Real2:= 1.0501924E-25
    ));
END_VAR

I had to play around with the byte order in the TIMESTAMP structure, depending on your platform, it might be different, I don't know. And the TIMESTAMPASHEX struct was just for information, you wouldn't really need it.

Hi,
I have two real numbers that represent timestamp - see the attached screenshot. Is there codesys function or structure that converts 2 real numbers into appropriate timestamp in a resolution of mSec. If codesys has no build-in support for this, what is the better way to perform it in ST?

Thanks
