Copy the wld file at a suited memory card. Plug this into your CPU and start it
again.
ð
The transfer of the application program from the memory card into the CPU
takes place depending on the file name after an overall reset or PowerON.
S7PROG.WLD
is read from the memory card after overall reset.
AUTOLOAD.WLD
is read from the memory card after PowerON.
The flickering of the yellow LED
of the status bar of the CPU
marks the active transfer. Please regard that your user memory serves for
enough space for your user program, otherwise your user program is not com-
pletely loaded and the red LED
of the status bar lights up.
4.9.3 Option: Transfer via MPI
For the transfer via MPI the use of the optionally available extension module EM M09 is
required. The extension module provides the interface X2: MPI(PB) with fixed pin assign-
ment.
Chapter 2.4 ‘Mounting’ on page 13
The structure of a MPI net is electrically identical with the structure of a PROFIBUS net.
This means the same rules are valid and you use the same components for the build-up.
The single participants are connected with each other via bus interface plugs and
PROFIBUS cables. Per default the MPI net runs with 187.5kbaud. VIPA CPUs are deliv-
ered with MPI address 2.
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.
