Design
The DP/AS-i F Link consists of a compact housing with degree of protection IP20.
The LEDs on the front panel of the DP/AS-i F Link indicate the current status and error
messages (device status, AS-i power/status, bus faults (PROFIBUS DP), group errors).
The DP/AS-i F Link three buttons for changing the mode, confirming a menu entry and
resetting to the factory settings.
Power is supplied via a 24 V DC power unit (PELV).

Function
PROFIBUS DP masters to DP-V0 or DP-V1 can exchange I/O data with lower-level AS-i
slaves cyclically.
PROFIBUS DP master with acyclic services complying with DP-V1 can also executed AS-i
command calls (fore example, read/write AS-i configuration during ongoing operation).
Apart from the digital I/O data, analog data is also stored quickly in the cyclic I/O area of a
failsafe S7-300/S7-416 F-CPU.
In configuration mode, DP/AS-i F-Link reads the configuration data of the I/O devices on the
AS-Interface. Slave addresses can be set and code sequences of secure AS-i slaves taught
in via the display and operator input keys.
