Hi, I wanna know how to connect the S7-200 plc to a computer. I have RS-232 cable(6ES7901-1BF00-0XA0), MPI-cable(6ES7901-0BF00-0AA0), STEP 7-Micro/WIN and WinCC flexible 2007. Is it possible with that?
 
Hi,

RS-232 cable(6ES7901-1BF00-0XA0)
is used for downloading to the HMI

MPI-cable(6ES7901-0BF00-0AA0)
Is the comm's cable between PLC & HMI.

You will need either

SERIAL RS232 PPI Lead
6ES79013CB300XA0
or
USB PPI Lead
6ES79013DB300XA0

Or aftermarket equivalent - PM member Genius in training
 
Ok thx, but they said they had already use the cables (6ES7901-0BF00-0AA0 AND 6ES7901-1BF00-0XA0) to connect the S7-200 to a pc, is that possible or I really need a new cable?

I also have a kinda thelephone cable connected to a serial adapter.

The plc port is ppi 485 serial protocol and a laptop serial port is RS232 so you need something to convert the signal to be compatible...

Is the PLC setup as an ethernet or modem module you may tie in there too but you will need configuration of the module to enter it on your laptop side (IP adress or phone number....)

Only plc with RS232 serial port can be directly connected with a pin to pin or nul modem cheap cable....and S7-200 isn't

so the cable you look for as a small grey box in it to be the serial data converter.

at this point you may ask who tell you: that he can do it with a simple serial cable to show you how...:) (Bring a bag of popcorn to past time ) Or to save time and be smart have him to give a call to a Siemens specialist to confirm what you read here....

It's ok, I found a pc/ppi cable, with that i'll probably be able to connect the S7-200 to my laptop

Finally, I'm not able to communicate with the S7-200 from STEP 7-MicroWIN 32, the cable I use is 6ES7901-3CB30-0XA0.

Thx
 
I did a step by step for a customer, you can see the pdf here.

If you still can't get communication then switch the PLC to stop mode by lifting the grey cover, the software may be using the port. The screen shots are for a computer running Vista.

I tried what your pdf said, it didn't work. So I switch the PLC to stop mode, it didn't work.

Anyone can help me?
