Running a simulink model from python script using TCP/IP

3 views (last 30 days)
import socket, struct
import matlab.engine
import os
eng = matlab.engine.start_matlab()
TCP_IP = 'localhost'
TCP_PORT = 30001
BUFFER_SIZE = 1024
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((TCP_IP, TCP_PORT))
print('Waiting for Simulink to start')
s.listen()
print("Waiting for connection")
-------------------------Stops at this point--------------------------------------------------------------
eng.sim('TCP')
conn, addr = s.accept()
print("Connection Accpeted")
print('Connection address: ', addr)
for i in range(51):
msg1 = struct.pack('>d', i)
conn.send(msg1)
print('sent data:', i)
data = conn.recv(BUFFER_SIZE)
print(data)
conn.close()
I am trying to run a simulink model which sends and receives data from python. The connection fails when I run the model through python scipt. Can anyone help me with the same.
