7.8 Siemens AS-i Link Device Support Block (Siemens DP/AS-i-Link DSB)
The Siemens DP/AS-i-Link DSB runs on the PGM and represents one PROFIBUS field device in the
PROFIBUS network. The Siemens DP/AS-i-Link DSB represents a PROFIBUS module and acts as a gateway
to an AS Interface bus. The Siemens AS-DP/AS-i-Link DSB processes the raw data from the Siemens DP/AS-i-
Link field devices and converts it to the PDC format supported by Experion. The Siemens DP/AS-i-Link
communicates with the master PGM for data conversion.
The Siemens DP/AS-i-Link supports the following two modules:
• Siemens DP/AS-i Link 20E
• Siemens DP/AS-i Link Advanced
The following table lists the functionalities supported by the Siemens DP/AS-i Link 20E and the Siemens
DP/AS-i Link Advanced modules.
Device
Supported functionality
Siemens DP/AS-i Link 20E
•
Up to 31 slave devices (no A/B extended slave addressing).
•
Up to 4 digital inputs/outputs per slave device using DP-V0.
Siemens DP/AS-i Link
Advanced
•
Supports both single master and double master AS-i (that is, up to two AS-i segments).
•
Up to 31 slave devices (no A/B extended slave addressing) per AS-i segment.
•
Up to 4 digital inputs/outputs per slave device using DP-V0.
The AS-Interface bus can access up to 31 devices and access up to 62 devices when extended addressing is
used. The Siemens DP/AS-i-Link acts as PROFIBUS slave device and AS-I master at the same time and allows
the PROFIBUS master to access devices on the AS-i-bus. The PROFIBUS slave device and AS-I master can
have up to four binary inputs and four binary outputs.
The device input or output data and status or diagnostic information from the Siemens DP/AS-I Link to the
PGM is communicated through DP-V0.

7.8.1 Functions of Siemens AS-i Link
Function
• Integrates the PROFIBUS DP slave devices to Experion.
• Reads data from field devices and writes output into field devices depending on whether the I/O module is
an input module or an output module.
• Processes extended diagnostic data and updates channel status and send notification based on the channel
status.
• Receives data from PIOMB and sends it to the device, if the PDC is connected to a PIOMB.
• Updates the PDC states.
