Is there another way to connect with PLC such as using profibus address or MPI

[ilmi]

Hello..,, currently my plc connected to PC via profibus, is it possible to access the PLC data if I installed python and snap7 lib inside the PC. If possible how should I setup the connection.

I already try to setup the connection like this :

profibus_address = 2
baud_rate = 187500
timeout = 1000

plc = snap7.client.Client()
plc.connect('PROFIBUS',profibus_address, baud_rate, timeout)

but I still get the error.

Thanks for you're help

Hi @ilmi
Snap7 does not support profibus. It only supports s7comm over tcp
Let me guess, ChatGPT gave you this code? :)

By the way, take a look at the pyprofibus library

Closing as answered. Snap7 only supports S7comm over TCP/IP. It does not support Profibus or MPI.
