4.4 Active components for interfacing to PROFIBUS PA
PROFIBUS Network Manual
94 System Manual, Edition 04/2009, C79000-G8976-C124-03
Definition
The DP/PA link consists of the IM 153-2 and up to a maximum of five DP/PA couplers. The
DP/PA link is a DP slave at the PROFIBUS DP end and a PA master at the PROFIBUS PA
end.
Application
With the DP/PA link, you have a decoupled interface from PROFIBUS PA to PROFIBUS DP
with transmission speeds of 9.6 kbps to 12 Mbps.
The following figure shows where the DP/PA Link fits in.

The DP/PA Link is configured with STEP 7, Version 4.02 or higher.
Properties
The DP/PA Link has the following characteristics:
● Diagnostics with LEDs and the user program
● DP slave and PA master
● Can be operated at all transmission speeds (9.6 kbps to 12 Mbps)
Mode of operation
The following figure shows how the DP/PA Link functions with the IM 153-2
(6ES7 153-2BA82-0XB0) and the DP/PA couplers.
● The DP/PA Link maps the underlying PROFIBUS PA system on a DP slave.
● With the DP/PA Link, PROFIBUS DP is completely decoupled from PROFIBUS PA.
