Is there any cable schematic that between S5 plc port and PC usb port?

Is it possible to buid my own cable from any schematic?

Thanks...

No, it's not possible. (it is but will not work!!) There is a "special" hardware (current loops) on the S5 port, so you need a special serial adapter.
Unfortunatelly.

OK, it's a bit trikky. All electronics is integrated into the 15 pin connector; the power supply comes from the PLC port. if U have a look in the documentation will find:

<<PG-UNI-Kabel
• Couples the PC (9pol. COM-interface) with the 15 pole X4/X5 interface port of the plc
• Galvanically separably to 1kV with PG ISO adapter
• Prolongable up to 300 meters
• Complete electronics in the plug housing• Supply from the PLC over the current sources of the PG-port
• Functioned also at some CP’s, IP’s and Sinumerik controls>>

so, not possible.
sorry for the bad news.
