Problems with Snap7 and Pyhton with S7-1200 #153

Closed geproelec closed 4 years ago

geproelec commented 4 years ago

HI,

I'm trying to communicate with a S7-1200. The ping from PC to S7-1200 is OK

My code is the next:

import snap7

IP = '192.168.0.1' RACK = 0 SLOT = 0

plc = snap7.client.Client() plc.connect(IP, RACK, SLOT)

print(plc.get_cpu_state())

And the error is the next:

========================================= RESTART: C:/Users/JUAN/Desktop/programas71200.py ========================================= Traceback (most recent call last): File "C:/Users/JUAN/Desktop/programas71200.py", line 7, in plc = snap7.client.Client() File "C:\Users\JUAN\AppData\Local\Programs\Python\Python38-32\lib\site-packages\snap7\client.py", line 38, in init self.library = load_library() File "C:\Users\JUAN\AppData\Local\Programs\Python\Python38-32\lib\site-packages\snap7\common.py", line 54, in load_library return Snap7Library(lib_location).cdll File "C:\Users\JUAN\AppData\Local\Programs\Python\Python38-32\lib\site-packages\snap7\common.py", line 46, in init raise Snap7Exception(msg) snap7.snap7exceptions.Snap7Exception: can't find snap7 library. If installed, try running ldconfig

Could you help me with this issue?

Thank you

Hi Jean,

The python code is missing the snap7 package it is using to connect to the PLC. Installing the python snap7 code is not enough.

The exception says you are missing the snap7 library. Now you need to install it and make sure python can find it.

So: Install the snap7 library. From sourceforge.

And/Or switch to Linux! :)

Cheers,

Stephan.
