SINEC-L2 DP = SINEC-L2 DP is the PROFIBUS DP for SIEMENS devices.
PROFIBUS DP
The Same Setup
The setup of an MPI network is basically the same as the setup of a
PROFIBUS-DP network. That is, the same setup rules apply, and you use the
same components for setting up both networks. There are only exceptions if
you set a transmission rate > 1.5 Mbps in the PROFIBUS-DP network. In this
case, you require special components which will be referred to in the relevant
section.
Since the setup of an MPI network does not differ from that of a
PROFIBUS-DP network, this section will simply refer to setting up a
network.
Setting up the You must assign MPI/L2 addresses to the individual nodes of an MPI or
Communication PROFIBUS-DP network to enable them to communicate with each other.
How you assign these addresses and what rules you must observe are
described in the STEP 7 manuals.
