PyXGT 1.1

Python connect to PLC LS

Python connect to PLC LS by TCP XGT Server

LS protocol(LS electric Communication Protocol) implementation by Python. LS protocol enables you to operate PLC from computer.

from PyXGT.LS import plc_ls

connect to PLC

conn = plc_ls("192.168.1.10",2004) #PLC LS IP and port: 2004 (TCP XGT server)
