Hello Everyone, I need to generate random value from 3.0 to 4.0 and 0.9 to 1.6 in the interval of 1s. I need this logic for testing purpose. I used tag simulator to generate this, it is working fine. But the problem is every time I have to start it manually. Let say if my pump is on then I need to generate this random value. When the pump is off then it should not give any value. I found multiple threads on this, I tried but not successful. I took the project from the below link Tool collection of functions for bit, number and mathematical operations - ID: 29851674 - Industry Support Siemens but here I am getting random values only from 0 to X STL/FBD/LAD solution will be helpful for me Thanks |
All is well :-) |

Hello. You are not stating which PLC & software you are using. That is a hinderance. The resource you found is already useful. Write a little code that transforms the value you already have to the range you need it to be. The resource you have is a value between -32768 and +32767. Another resource: Library of general functions (LGF) for SIMATIC STEP 7 (TIA Portal) and SIMATIC S7-1200 / S7-1500 :: LGF_Random_Real() ~ |
