I'm hoping some of you experienced Siemens folk will help me on this one. I have a Siemens S7 224 and associated PPI/PC Cable for downloading the program to the S7. That works well. But when I connect the PPI/PC cable (its a USB connection at the PC), I get the following PC error message, "Could not establish connection. Please check your settings, interface cable, etc!" Another screen says, " Download Failed. Please check the following, 1) Cable connections between PC and TP, 2) Port number selected for comm between PC and TP (it is COM1 and 38400 baud rate), 3) TP is in the serial download mode before starting download
I'm hoping that someone has been here and done that; and has the answer. At first I was connected to a D-Link USB hub. But I recently tried directly to a USB port on the computer. Still nothing successful.
Thanks.
