DP/PA Link
Definition
The DP/PA link consists of the IM 157 and up to a maximum of five DP/PA
couplers. The DP/PA link is a DP slave at the PROFIBUS-DP side and a PA
master at the PROFIBUS-PA side.
Uses
With the DP/PA link, you have an isolated interconnection between PROFIBUS-PA
and PROFIBUS-DP with transmission rates of 9.6 Kbps to
12 Mbps.
The DP/PA link can only be used in SIMATIC S7.
Figure 2-16 below shows where the DP/PA link fits in.
