hello to all

I need to connect a S5-95U to a commercial PC and i don't have the interface to make it,but I have an idea and i want to consult it with you and that you give me your opinions.
I have a bus driver C73451-A347-B202 (and the power pack 6DR2900-8BA ) for to connect several SIPART DRs with interfaces RS232 (conector DB9 in the bus driver), to a PC using communication RS232 or to a CP 524/544B of a S5 using TTY (conector DB25 in the bus driver).
The idea is the following one:
 - I configure the bus driver for the communication with a CP of a S5 through TTY and the communication with the SIPART DRs is with RS232 always, of course.
- Knowing the distribution of pins of each side, I build two connection cables, for to use the connection RS232 of the bus driver (for the SIPART DRs) for the PC port and the connection TTY (for the CP) with for the S5 port(SINEC L1).

what do you say?

Hello,
You can try to buy an interface cable from Process Informatik company. They have USB - S5 cable and I have tried it and it's easy to use.
Hope this helps.

Hello jm1983,

If you use a PC with serial RS232 interface you can take the PC converter cable with the order number 6ES5734-1BD20.
The interface assignment of the PC converter cable finds you here:
http://support.automation.siemens.com/WW/view/en/13063839

Here a further recommendation. I think this solution is better.
Köster-Box (PC-S5-Interface)

Interface for programming Siemens S5-PLCs with the PC.
The Kösterbox converts the RS232 signals of the PC into TTY signals (20mA) of the automation system.

• The box is full duplex, send- and recieve channel,
• the box is active for programming S5 90-115U,
• for S5-135/155U and CP or acting passively with other cable,
• the box has its own power supply with galvanic separation

Her the link:

Best regards

Thanks a lot for your answers.
I don't have the money to buy an interface, therefore I need to make one. Can you help me in this?.

Thanks in advanced.
