I don't know why, but exactly the same project behaves in different way in simulation and with real PLC. In simulation the project works fine (I'm talking about my version, the one that you tried also), but with real PLC (VIPA) it happens what I said.
Your last version (wich commands all timers one by one) works fine also in real PLC instead.
Now I don't have the possibility to test it with SIEMENS PLC ( I have only VIPA available). If you are sure that with SIEMENS real PLC it works, my conclusion is that VIPA and SIEMENS behaves in different ways...
thank you anyway for your help, but I think I won't use loops to command timers....
