using bit shift to retrieve a value

Hello,

I'm having trouble with a scl function block I try to create.

I want to create a function block that takes a 32 bit peripherie input from an IO link master : I address 4...35. and outputs the 4 values inside this 32 bit input :

bit 0 (LSB) = pnp output 1
bit 1 = pnp output 2
bit 2 = temperature value (14 bit)
bit 16 = pressure value in % (16 bit)

What I tried first is using IW4 (#inputWord1) and IW20 (#InputWord2) as the parameters for this function block, then I thought I could retrieve the 2 values : temperature and pressure using the following code :

In both cases you should cast to REAL before dividing. It might be redundant if you divide by REAL constant, i.e. 10.0 or 100.0 respectively. If the later doesn't work try also REAL#10.0/REAL#100.0.

BTW, shifting right is the only right direction in this case. 

 You are right, the solution was a Right bit shift and a conversion afterwards.

I still need to find a way now to retrieve the 2 bits seperatly :)

thanx!!!
