Hello all!

As i read many topics in this forum about my issue, i have conclude that in order to communicate with my PC and the CPUs S5 135U - S5 115U, I need the communication cable with order number 6ES5734-1BD20. Am I right?

I don't have RS232 port on my PC so i am going to use a converter USB to RS232. But, is there any cable from Siemens with USB connector in order to avoid the converter?

Many thanks

Lampros

Hello,

No, Siemens does not offer a cable with USB connection.

If you google, you will find some other brands, who deliver it.

 So, the safe way is to use the communication cable with order number 6ES5734-1BD20. ?

Is this order number right?
