I am trying to figure out how I can create a generic "numeric" parameter to an FB.  I would like to pass in a parameter that might be Byte, Int, Uint, Word, Dint, UDint, DWord, Real, or LReal.  Any suggestions on how to do this?  Or is it even possible?  And if you have a solution, please give an example of how I could access or convert the parameter value to a common data type (preferably in SCL).

Thanks in advance!

Hi Jazzgeek,

You could make the input type ANY and use smiffy's answer in this thread ANY pointer in SCL to decode it.

pAny.DataType would tell you what type it is (Byte, Int etc.) then you can use BLKMOV to get the value into a variable of the right type to suit.

Hope that helps,

Brian
