Guest Aldo Posted August 11, 2003 Report Posted August 11, 2003 Hi, i'm used siemen S7-300 for the first time, so i didn't know to much, can we make direct connection between PC to S7-300 cpu 314? if we can connect directly, would you like to give me the drawing for the pin number for each connector, because i have looked for it at operational manual of S7-300 but i couldn't found it. Thank's before Quote
Guest Fritz_frederix Posted August 12, 2003 Report Posted August 12, 2003 Hi there, If you would like to connect a PC to an S7-300 plc I suggest that U should use an communication card. For ethernet is this CP 343-1 For Profibus is CP 343-5 see ya Quote
Guest passerby Posted December 13, 2003 Report Posted December 13, 2003 you can look for it at cp340 manual Quote
Guest Labotomi Posted December 13, 2003 Report Posted December 13, 2003 You'll need a serial to MPI adapter from siemens. From what I've read about it, no one has reverse engineered it. I think it's between $300-$400US Quote
