The DP/AS‑Interface Link 20E is a PROFIBUS DP slave (according to IEC 61158 / IEC 61784) and an AS‑Interface master (according to IEC 62026‑2). It enables the AS‑Interface to be operated on PROFIBUS DP.

Up to 248 DI / 248 DQ can be operated via the DP/AS‑Interface Link 20E using 62 A/B slaves with 4 DI / 4 DQ each.

PROFIBUS DP masters (DP-V0) can exchange digital I/O data cyclically with the AS-Interface.

PROFIBUS DP masters with acyclic services (DP-V1) are also able to exchange analog I/O data and initiate AS-Interface master calls (e. g. reading/writing the AS-i configuration during normal operation).
