I have an old machine at a customer with problems regarding enable signals and it seems there is an faulty spindle drive unit. 

The card number: 6SN1121-0BA13-0AA0

As soon as I put the connector with the enable signals in (pin 9,663,65,81), the complete system goes down (central enable signal on the ER-module on pin 9 goes down).

Before changing the card I would like to save the parameters. On display I see 000 - 399; and a lot of them have subparameters so writing them down is a lot of work.

How can I backup these parameters? I tried SimoCom A and SimoCom U with a serial cable (pin 2,3,5)  but they don't work. Packages are too new?

Thanks for the information! I've found the mentioned software and will make the cable and going to try.

But If it doesn't work with the cable, and I have to remove the eprom, Is it still possible for a repair shop to repair the faulty card?

I hope they can repair the card.

It has been followed up with 3 newer cards since the build of the machine. The latest version is partially compatible according to Siemens Service. Problem: I do not know what the differences are. Is it only the software? or perhaps different values in parameters? or other connections on the front?

The 6SN1121-0BA13-0AA0 has been followed up with the 6SN1121-0BA11-0AA1, then with the 6SN1118-0NH01-0AA0 (partially compatible), then 6SN1118-0NH01-0AA1 which can be ordered on special request in Germany. Delivery time unknown...
