WinCC flexible® Runtime and eVCOM

Using WinCC flexible@ Runtime through an eWON eVCOM connection, you may encounter connection interruptions when a page with many tags is displayed.

To solve the problem, in WinCC disable the "Cyclic operation" in the Connection Settings. See picture hereunder. 

The "Cyclic operation" option allows data exchange optimization between the PLC and the HMI device but is not supported by the eWON eVCOM solution.
