jdaniel Posted January 30, 2006 Report Posted January 30, 2006 Hi. Good It’s the first time that I use this forum… I have a problem with a Siemens PLC S7 300… When I try to download the program to the PLC with a MPI PC Adapter v 5.1 the program displays an error message “Download 33:16662 (Online: the connection to the target module cannot be established)” . If the option (PG/PC is only master on the bus) is off the message become “Download 33:16944 (Online: No other active partner can be found) “… So, I can’t download the program… If Anybody can help me I appreciate.. Thanks … booty: Jorge Costa Quote
Guest Fritz_frederix Posted January 30, 2006 Report Posted January 30, 2006 Hello, Are you sure that the connection type is correct. You can find this back in the PG/PC interface. Most likely profibus is choosen change this to MPI interface. Rudi Quote
jdaniel Posted January 30, 2006 Author Report Posted January 30, 2006 Hi! Yes the PG/PC interface is the MPI.... It was alredy selected.... but the error message continue.... booty: Jorge Costa Quote
JesperMP Posted January 31, 2006 Report Posted January 31, 2006 Hi Jorge. Under the Set PG/PC interface, do you have 19200 or 38400 baud set ? This must match the setting on the PC adapter (I believe there is a small switch on the adapter). Is the COM port you are using not hooked by other applications ? Some programs or drivers takes control of the COM port and does not allow others to use it. Example: Rockwell RSLinx set to DF1 or PIC driver. Try to use the same MPI adapter on another CPU. Try to use another MPI adapter on the same CPU. Quote
