The MPI programming cables are available at VIPA in different variants. The cables pro-
vide a RS232 res. USB plug for the PC and a bus enabled RS485 plug for the CPU. Due
to the RS485 connection you may plug the MPI programming cables directly to an
already plugged plug on the RS485 jack. Every bus participant identifies itself at the bus
with an unique address, in the course of the address 0 is reserved for programming
devices.
A cable has to be terminated with its surge impedance. For this you switch on the termi-
nating resistor at the first and the last participant of a network or a segment. Please make
sure that the participants with the activated terminating resistors are always power sup-
plied. Otherwise it may cause interferences on the bus.

A hardware configuration to enable the MPI interface is not necessary. By installing the
extension module EM M09 the MPI interface is enabled.
1.
Turn off the power supply.
2.
3.
Switch on the power supply.

After a short boot time the interface X2 MPI(PB) is ready for MPI communica-
tion with the MPI address 2.
1.
Connect your PC to the MPI jack of your CPU via a MPI programming cable.
2.
Load your project in the SIMATIC Manager from Siemens.
3.
Choose in the menu
‘Options
è
Set PG/PC interface’
.
4.
Select in the according list the "PC Adapter (MPI)"; if appropriate you have to add it
first, then click on [Properties].
5.
Set in the register MPI the transfer parameters of your MPI net and type a valid
address.
6.
