I need a function or method to check Modbus Server is available or not

sourceperl commented 2 years ago 
import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = sock.connect_ex(('localhost', 502))

if result == 0:
   print('server is alive at localhost:502')
else:
   print('server is dead')

sock.close()
