X-Gateway which GSD file for Profibus slave?

I want to communicate with existing (I think?) AB7634 with net2=Profibus slave.
It was installed approx 2008, so I think on HMS website I have to look in “X-Gateway Classic” area.
On website, under Classic, I found HMS_1013.GSD and HMSB1013.GSD.
I know it depends on firmware version.
How can I find out what firmware customer has??

Customer connected to unit with config software, and shows version, but I wonder if that is only version of the config software.

What is the serial number of the Anybus?

Here it is:

That gateway has 3.14.01 firmware.

Here is the correct GSD: HMSB1013.GSD (4.3 KB)
