I'm trying to build a communication between a plc s7 1200 and an rpi 3, I have installed snap7 but when executing this code I get the following error:
no module named snap7
This is my code:
from time import sleep
import snap7
from snap7.util import *
import struct
plc = snap7.client.Client()
plc.connect("192.168.12.73",0,1)
area = 0x82 # area for Q memory
start = 0 # location we are going to start the read
length = 1 # length in bytes of the read
bit = 0 # which bit in the Q memory byte we are reading
byte = plc.read_area(area,0,start,length)
print "Q0.0:",get_bool(mbyte,0,bit)
plc.disconnect()
