What's the differences between a UINT and a WORD with Profinet

I'm developing a project on a Siemens PLC and i'm wondering if I should use a Word or a UINT to store a 16-bit value. Is there any differences between the two?

Solution

  • Generally there is no real difference between the two. The only time where it really matters is when the input type to a function block is either a WORD or UINT. Then it will matter.

    Generally speaking, if you are choosing between a UINT or a WORD to store a numerical value the typical best practice is go ahead an use an UINT. If you are looking to store a hex value you would want to use the WORD.
