Important

The type consistency of the variable exchange is guaranteed only if the application versions on the EtherCAT Safety Module and on the main controller correspond to the version of the same compilable project.

Only data whose variables have a standard data type can be exchanged. Variables of a data type with the SAFE prefix cannot be exchanged between a EtherCAT Safety Module and a standard controller.

A change of the variable exchange can only become active by downloading the safety application and the standard application again.
