IEC61850: connection lost but varaibles non updated

Hi,
i have a big problem in zenon, in particular in IEC61850 client driver.
Driver has 20 connections to different RTUs.
Problem appears when I turn off RTU. I will aspect that driver has INVALID status for each variables of that RTU, instead Zenon reads the last value and variables are not updated with INVALID status until a Zenon restart.
Only after a Zenon restart, variables have INVALID status.
This problem doesn't appear on each RTUs, only on some of them.
Herewith attached some print screen of driver configuration.
driver_Aggiornato.png containts connection configuration to variables correctly read and updated.
driver_NonAggiornato.png containts connection configuration to variables that are NO correctly read and updated.
