Simatic OP27 IF1 & IF2 Cables

[olatz.recio]

Hi everyone!

I am looking for some cables to connect an OP27 to a PC, both for the IF1 Interface and the IF2. Does anybody know what kind of cables I should be looking for?

Thank you in anticipation.

Best regards,

hi
IF1 needs serial cable and IF2 may be serial or MPI/Profibus...
you have to set in the system screen,..

IF1A and IF1B are used for the online connection to the PLC.
The pinout is totally dependent on which type online connection you intend to use.

IF2 is used for download from a PC to the panel (and sometimes for attaching a printer).
For IF2 PC-to-OP27, the cable type # is: 6XV1440-2KH32
On the 15-pin OP plug is noted: "TD/OP V.24". Insert in IF2 port on the OP.
On the 9-pin PC plug is noted: "TI505/PC V.24". Insert in serial port on the PC.

Or Do it yourself description:

OP plug:            PC plug:

15-pin male         9-pin female

pin 1 shield ------ pin 1 shield

pin 3 RxD    ------ pin 3 TxD

pin 4 TxD    ------ pin 2 RxD

pin 12 Gnd   ------ pin 5 Gnd

pin 1-6-4 jumper

pin 7-8 jumper

Notice: This is for a standard 9-pin serial port in a standard PC.
If you have a Siemens PG, then the cable is not the same.
