Hi,
if you cannot connect to the PLC you might have some problem with the configuration of the port (or the serial converter). However, there isn't a way to upload the program code form a PL260, You can only read the values of the Word in RAM o in EEprom.
So, if you need to make modification in the program code, you need the source code file .PLP
