定期检查MODBUS TCP设备与客户端的连接状态

import socket
import time


# 设备信息
ip_address = '192.168.10.11'
port = 5020


def check_connection(ip, port):
    try:
        client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        client_socket.settimeout(1)  # 设置超时时间为1秒
        client_socket.connect((ip, port))
        client_socket.close()
        return True
    except Exception as e:
        return False


try:
    while True:
        connection_status = check_connection(ip_address, port)

        if connection_status:
            print("设备连接成功.")
        else:
            print("设备连接失败！")

        time.sleep(1)  # 暂停5秒后继续循环

except KeyboardInterrupt:
    # 当用户按下Ctrl+C时，终止循环并关闭连接
    pass

# 关闭连接
# client_socket.close()
