Random Numbers

The link listed for Quantum Automation is not good anymore, and I couldn't find it on their site. Does anyone have this or know of a simple way to generate random numbers in a DL06 or similar?

I know that generating random numbers is good for testing, but are there PLC applications that need random number generation?

What type numbers? BCD or binary, single or double word, real? What range?

I know that generating random numbers is good for testing, but are there PLC applications that need random number generation?

A lot of folks want random numbers to switch between pumps or other devices to even out wear. There are actually quite a few applications for randomness in PLC's.

Atatched is a DL05 program for 16 bit random in V2000. (You may have to modify the First Scan code to place a non-zero number into V2000).

Random Numbers

bcarlton, thanks for taking the time to post your random number code. It was very helpful for my application. I am using a DL05 to run simulations that require random timing between events (and this is very difficult without something to generate random numbers!)

Does anyone have an elegant method to generate a random number on a DL250? I suppose I could do something with the scan number and/or the RTC, but I was hoping for something a little better...

I'm not sure about elegance but here's an example.

Quantum Automation has posted other example programs in their Application section.
