Configuring MPI Networks and
PROFIBUS-DP Networks
! You can
S
integrate the C7-626 via the MPI into an MPI network.
S
integrate the C7-626 DP via the MPI into an MPI network or set up a
PROFIBUS-DP network via the PROFIBUS-DP interface.
SINEC-L2 DP is the PROFIBUS DP for SIEMENS devices.
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.
You must assign MPI/L2 addresses to the individual nodes of an MPI or
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.
