I tried to enumerate the plc through nmap s7-enumerate and I got this output

Starting Nmap 7.60 ( https://nmap.org ) at 2020-05-01 21:15 IST Nmap scan report for 172.17.0.2 Host is up (0.000092s latency).

Is there a way to change attributes like serial no , module type , system name and also add plant identification?

Hi! These parameters are hard coded into snap7. I found in the code, that they was just recorded from a real Siemens hardware. I can also see where this bytes are stored, src/core/s7_firmware.h, but I have no way to create an additional function in my code in order to change them.
