Random number generator in Vijeo Citect SCADA

Hello,

Could somebody please help me out with coding a 'Random number generator' in vijeo citect.

For example if i create an analog Local variable, i would want that variable number to change every 2to3 secs with numbers between 0 to 240.

I tried using the Rand() function, all i got it to do is change from 0 to 1. I am a bit weak and new to citect as I've been working with it for barely a month.

I would really appreciate any input or an example code on this.

Thank You.

Try:

variable = Rand(241);

Thank you Nhatsen,
Is there a way to update it every few seconds?

variable = Rand(241);
the above only give a '0' in run mode

Just call that function from an event on the timebase that you need it
