noob question about HMI system on easy plc 5

[Giovanni74]

good morning, sorry for the noob question 

I have a problem, I can't use the HMI system in my programs, the software is installed correctly because the HMI program examples provided work.
 a simple example, I create a page, I put a button on it, I associate it with a digital input, I save the program, I compile it, I launch the virtual plc, I launch the HMI system, I put the plc into run. now if I click the button created on page 0 of the HMI, the digital input associated with the button does not change state. I can't understand why, if I look in the example code it's all the same and it works.

Hi Giovanni.

Send your plc program to info@nirtec.com in order to analyze it.
