Hi every body

I am trying to create a FC for converting real value to word in pcs7.

I found a block that convert real to double word and other block that convert double word to word in CFC chart.

When I want to use these blocks in FC, I can not find the block that convert double word to word.

How can I find that or create this FC?

Thanks

Hi Salman,

If i understand correct that you want to create your own FC block.

When creating in SCL the following function is availible:

DWORD_TO_WORD Copies the 16 least significant bits

More information can be found in the manual S7-SCL V5.3 for S7-300/400 Chapter 14-4
