Kết nối không dây giữa PLC và HMI bằng thiết bị Moxa AWK

Giải pháp này sử dụng bộ phát không dây công nghiệp Moxa AWK-1131A đóng vai trò Access Point (AP) và bộ AWK-1137C đóng vai trò Client để kết nối không dây giữa PLC và HMI thông qua giao tiếp Ethernet. Đây là giải pháp lý tưởng cho các nhà máy cần kết nối linh hoạt, tránh kéo dây phức tạp.

1. Mô hình kết nối

Kết nối PLC với HMI qau wifi bằng Moxa AWK-1131A và AWK-1137C

  • AWK-1131A (AP): Gắn vào PLC qua cổng Ethernet RJ45.
  • AWK-1137C (Client): Gắn vào HMI qua cổng Ethernet RJ45.
  • Kết nối không dây giữa hai thiết bị qua chuẩn Wi-Fi IEEE 802.11n.

2. Ưu điểm của giải pháp

  • Loại bỏ dây tín hiệu giữa PLC và HMI.
  • Linh hoạt trong thay đổi vị trí HMI trong xưởng.
  • Hỗ trợ giao tiếp liền mạch với các giao thức như Modbus TCP, Ethernet/IP,...
  • Tốc độ cao, độ trễ thấp, phù hợp cho giám sát và điều khiển thời gian thực.
  • Thiết bị công nghiệp, chịu nhiệt, chống nhiễu cao.

3. Ứng dụng thực tế

Giải pháp này được sử dụng trong các nhà máy CNC, dây chuyền đóng gói, hệ thống SCADA, hoặc bất kỳ ứng dụng nào yêu cầu kết nối linh hoạt giữa thiết bị điều khiển và giao diện người vận hành.

4. Cấu hình cơ bản

  1. Cấu hình AWK-1131A ở chế độ AP, đặt SSID và mật khẩu bảo mật WPA2.
  2. Cấu hình AWK-1137C ở chế độ Client, kết nối đúng SSID.
  3. Đảm bảo địa chỉ IP của PLC và HMI cùng dải mạng.
  4. Kiểm tra kết nối bằng lệnh ping hoặc giao diện HMI.
