I have Siemens PLC (S7-200 CPU 224 ) with software package (STEP7-Micro/WIN 32 Version 2.1)and PC-PPI interface cable.
When using the UPLOAD function in order to copy the user program stored in the PLC to my personal computer the system display message which indicate that it is not possible to copy the user program.
Can any body tell me what could be the reason for not possible to upload the user program from the PLC.
Note: The communication was tested and working properly.
