■ Overview
DP/AS-Interface Link 20E
DP/AS-Interface Link 20E connects PROFIBUS DP to
AS-Interface. It performs the following functions:
• PROFIBUS DP slave and AS-Interface master
• Connection of up to 62 AS-Interface slaves and integrated
analog value transmission (according to the extended
AS-Interface specification V2.1)
• Supports all AS-Interface master functions according to the
extended AS-Interface specification V2.1, i.e. master class M3
• Supply from AS-Interface cable; hence no additional power
supply required
• Supports the uploading of the AS-Interface configuration in
STEP 7 V5.2 and higher

PN DP-M DP-S ASi-M
■ Benefits
• Reduction of installation costs because the power supply
comes completely from the AS-Interface cable, making an additional
power supply superfluous.
• Short start-up times through simple configuration at the press
of a button
• Reduction of standstill and servicing times in the event of
slave failure thanks to the LED indicators
• Easy and fast start-up through reading out the AS-Interface
configuration (ES03 and higher)
