Yes this should be straightforward to do in EMS. Most of the EMS calling points are going to call your program every timestep,
and when you use @RandomUniform it will produce a new random number each time that line of the EMS program executes.

Hi All,
Is it possible to generate random number by using EMS that will be applied every timestep. I saw in the manual that random numbers could be generated by using @RandomUniform and/or @RandomNormal built functions but I do not know how to set it to change every timestep.
For my project I have to vary temperature setpoint every 15 min by adding and subtracting 0.5C depending on the random number. For example, random number is between 1 and 10 and if it is <3 0.5C is added to setpoint, if it is >8 0.5 is subtracted and the rest of time no change occurs.
Many thanks,
Regards,
Miroslava
