Problems connecting a SIEMENS MICROMASTER 440 with a PC

3 posts in this topic

I recently purchased the SIEMENS CONNECTION KIT (6ES6400-1PC00-0AA0) with its corresponding serial cable to connect to a MICROMASTER 440.
I connect my RS232-USB cable to the serial cable. But I can not connect in any way!
What do I do wrong?

1. In the micromaster 440 I put the following USS configuration parameters (USS = serial communication):
   p2010 = 6
   p2011 = 0
   p2012 = 2
   p2013 = 127

2. I put the DIP of the Connection Kit (Ref. 6ES6400-1PC00-0AA0)  1 ON, 2 OFF, as indicated in the manual.
   I connect the connection kit module with its serial cable to my RS232-USB cable. And I connect the USB to my PC.

3. Open "Set PG / PC interface" and select PC COM-Port.USS.1
4. I go to the properties and I am selected COM1 without problems.
5. But I do the transmission speed test and can not find anything.
6. Also in the diagnosis of PC COM-Port.USS.1 I do the test and can not find anything.

Supposedly my RS232 cable is correct (I have tried several tests).
And the configuration of the COM port in "device manager" also looks correct.

What am I doing wrong??

Zhanks!

Likely an issue with your USB to RS232 adapter.  Many of them just don't function well with automation and controls.  Which one are you using?

Are you 100% certain it installed as COM1?

I'm 100% sure that it was installed as COM1.
I tested a pair of RS32 cables. I do not think it's that.

I have tested the following possibilities with STARTER:

DEVICE (STARTER, SCOUT) -> PC COM-Port.USS1
DEVICE (STARTER, SCOUT) -> USB.S7USB.1
S7ONLINE (STEP 7) -> PC COM-Port.USS1
S7ONLINE (STEP 7) -> USB.S7USB.1

Also with the Drive Monitor:
S7ONLINE (STEP 7) -> PC COM-Port.USS1
S7ONLINE (STEP 7) -> USB.S7USB.1

Unsuccessfully. I think that in all cases the LED of the USB-RS232 blinks me as if it were working.

I have even tried a computer with a serial port (no need for RS232) but I do not see the option PC COM-Port.USS1 in the PG/PC interface
