1.2 Application of the Module
DP Slave and AS-Interface Master
The DP/AS-i Link 20E module is both a PROFIBUS DP slave and an AS master at
the same time:
S The DP/AS-i Link 20E module connects the actuator-sensor interface with
PROFIBUS DP.
S Using the DP/AS-i Link 20E module, you can access the inputs and outputs of
the AS-i slaves from PROFIBUS DP. Depending on the slave type, you can
access binary values or analog values.
The following AS-i slaves can be used:
– Standard Slaves / AS–i Analog Slaves
– Slaves with the extended addressing mode
