See manual, Section 5.3.9.
1.2.5.2 Implementing a User Acknowledgment in the Safety Program of
the F-CPU of an Intelligent DP Slave
Options for User Acknowledgment
You can implement a user acknowledgment in one of the following ways:
1. An operator control and monitoring system with which you can access the
F-CPU of the intelligent DP slave
2. An acknowledgment key that you connect at an F-I/O with inputs that is
assigned to the F-CPU of the intelligent DP slave
3. An acknowledgment key that you connect at an F-I/O with inputs that is
assigned to the F-CPU of the DP master
These three options are illustrated in the figure below.
