I did diploma project at TIA Portal V11. I try to do SCADA of a part of substation. I want to simulate  amperage, voltage, frequency at high-voltage line (like include randomize.h at C++, random() at pascal). I do not know how to do it. Maybe I need to use function from plcsim? 

 Hello,

What type of controller you want to implement a random number generation algorithm?For S7-300/400, there is OSCAT library , with many signal generating and processing function, is available HERE.It is an archived project(library) for STEP 7 and  can be migrated to TIA Portal.

Also, you have option of searching the forum to find out plenty of helping threads.Check the following as a sample:

I hope these comments help you,
