 Hello marisa,

 If you use STEP7 "classic"  have a look the thread of IBN Service:

Hi marisa,

Siemens has a tool collection of functions for bit, number and mathematical operations.

There you can find a "Random number generator".

Please look here:

It´s for numbers between -32768 to +32767.

You can convert to real, divide with 32768 and do the absolute value....so you have numbers between 0 and 1.

There is already a library for that, check this link

Library of general functions (LGF) for STEP 7 (TIA Portal) and S7-1200 / S7-1500
