I want to connect a 115 U directely on a PC , and use for that a converter RS 232/ TTY !!!
but I am not a specialist !!
I have try to see in a cable 6ES5 734 from siemens how are the connections, but from the PLC side the connections are on the pins 7,2,11,14 and if you could see on the documentation of the PG 730, we could see on the drawing that the pins 2,7,9,6 are connected ? ?? so I dont know how to connect my PC on the 115U without using a cable from siemens.

Thanks in advance if you could help me.
