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.

1.
Connect your PC to the MPI jack of your CPU via a MPI programming cable.
2.
Load your project in the Siemens SIMATIC Manager.
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.
Switch to the register
Local connection
.
7.
Set the COM port of the PC and the transfer rate 38400baud for the MPI program-
ming cable.
8.
Transfer your project via
‘PLC
è
Load to module’
via MPI to the CPU and save it
with
‘PLC
è
Copy RAM to ROM’
on a memory card if one is plugged.
5.9.2 Transfer via Ethernet
For transfer via Ethernet the CPU has the following interface:
n
X5: Ethernet PG/OP channel
So that you may access the Ethernet PG/OP channel you have to assign IP address
parameters by means of the "initialization".

Ethernet PG/OP channel’ page 54
1.
For the transfer, connect, if not already done, the appropriate Ethernet port to your
Ethernet.
2.
Open your project with the Siemens SIMATIC Manager.
