BYTE, WORD, DWORD, SINT, USINT, INT, UINT, DINT, and UDINT are all integer data types.
Each of the different number types covers a different range of values. The following range limitations apply to the integer data types:

As a result when larger types are converted to smaller types, information may be lost.
