4. Copy the wld file at a suited memory card. Plug this into your CPU and start itagain.ð The transfer of the application program from the memory card into the CPUtakes 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 CPUmarks the active transfer. Please regard that your user memory serves forenough 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 MPIFor the transfer via MPI the use of the optionally available extension module EM M09 isrequired. The extension module provides the interface X2: MPI(PB) with fixed pin assign-ment.Ä Chapter 2.4 ‘Mounting’ on page 13The 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 andPROFIBUS 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. Dueto the RS485 connection you may plug the MPI programming cables directly to analready plugged plug on the RS485 jack. Every bus participant identifies itself at the buswith an unique address, in the course of the address 0 is reserved for programmingdevices.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 makesure that the participants with the activated terminating resistors are always power sup-plied. Otherwise it may cause interferences on the bus.1 MPI programming cable2 Activate the terminating resistor via switch3 MPI networkGeneralNet structureMPI programming cableTerminating resistorVIPA System MICRO Deployment CPU M13-CCF0000Project transfer > Option: Transfer via MPIHB400 | CPU | M13-CCF0000 | en | 16-47 69
