MessageBox in the target system

Situation

On the target system (with MS XP/XPe/7/WES) TwinCAT message boxes ("PopUp windows") are displayed during operation which require confirmation, for example by clicking "OK". If target system is in production mode without HMI (visualization, monitor, keyboard, mouse) and/or no machine operator is present, the message box cannot be confirmed. In this case logger outputs are no longer displayed on the programming device/TwinCAT linked via ADS.

Solution

Set a RegistryKey on the target system to suppress the TwinCAT information window.

It is not advisable to set this key as default, because TwinCAT information windows would no longer be displayed at all.
