You can try to use LECPython module, I think this is a great choice for you.

from LECPython import LECPython
from time import sleep
 
lecp = LECPython()
res = lecp.SiemensS7NetConnection("S200", "192.168.0.2", 102, 0x02, 0x03, "CDAB", True, 2000)
 
if res["IsSuccess"]:
    plc = res["Content"]
    print("Connection success")
else:
    print("Connection error")
 
# Read memory flag M1
r = lecp.ReadNodeValues(plc, "V1104.0", "bool", 1)
print("M1: ", r["Content"])

# Read output V1064.0
r = lecp.ReadNodeValues(plc, "V1064.0", "bool", 1)
print("Q1:", r["Content"])
