3. Connect the cable to the MPI/DP interface.
Caution
Before plugging in the cables, the static charge on your body, the unit, and the
cables must be equalized. You can do this by briefly touching the metal mounting
plate for the interfaces on the rear panel.
*) Electrical isolation in the safety extra-low voltage circuit (SELV circuit).
Connecting
Via the MPI/DP interface, you can connect your programming devices to
•
MPI networks (S7-200, S7-300, and S7-400) or
•
PROFIBUS DP networks (DP components).
MPI/PROFIBUS DP Network
Up to 32 devices (PC, PG, or AS) can be connected to the MPI/DP interface to
form a network segment. The physical connection to the MPI/PROFIBUS DP
network is via a floating RS485 interface which is a component of the PG basic
module.
Several MPI/PROFIBUS DP network segments can be connected via repeaters.
The complete MPI/PROFIBUS DP network can comprise up to 127 stations. Data
transmission rates from 9.6 Kbps to 12 Mbps are possible in the PROFIBUS-DP
MPI network.
