3.5.12.2 Measuring socket assignment
The process data acquisition system (PADU8) is used for the diagnosis of analog and digital
converter signals. The process data acquisition system is designed as an optional component.
If the PADU8 is not included, the signals can be read out with the aid of an oscilloscope, for
example, at measuring sockets.
