In TwinCAT the settings for the Reaction to IP-Link error can be transferred with ADSRead and ADSWrite (ADS: Automation Device Specification). For this purpose they should be activated in the User_Prm_Data.

The settings for the Reaction to IP-Link error function are found in the TwinCAT System Manager on the "PrmData" tab for the corresponding Bus Coupler.
