Accessing As-I Binary Data - Siemens DP/AS-Interface Link 20E Manual

2.3.2

Accessing AS-i Binary Data

The DP Master is the Decisive Factor
The way in which you access binary data of the AS-i slaves depends on the DP
master you are using. Please refer to the relevant user documentation.
A SIMATIC S7 is the DP master
If you have configured the I/O addresses of the DP/AS-i Link 20E in the area of the
process image, you can access the AS-i bit values using single bit commands.
