  1. Hello,

    What are the retentive area’s of memory? Is retentive memory eeProm or battery backup?
    Can you have 2 types of AI 4 x NTC 10K & 4 x 0-20mA?
    Can you use GX Works 2 to program?

  2. Muy buenas estimad@s en la linea LK3U veo que tiene para celula de pesaje pero mi duda es: que tan exacta es, cual es la velocidad de refresqueo(HZ) y si tiene algun video o ejemplo real para mas informacion. gracias saludos

  3. Xin chào,

    Cho mình hỏi thời gian thực của các dòng PLC LE3u, LK3u, Fk3u và HMI Kinseal thì loại nào chạy đúng nhất trong 4 loại thiết bị mình vừa nêu ra. Vì có luồng ý kiến PlC hãng chạy đúng với thời gian thực nhất, nhưng cũng có ý kiến HMI tốt hơn. Vì vậy, mong rằng bạn giải đáp thắc mắc này cho mình !
    Xin chân thành cảm ơn.

  4. – Vì sao tốc độ baud của PLC LE3U, LK3U và FK3U là 38400bps
    – Nhưng khi truyền thông RS485 với HMI Kinseal 7.3inch, thì tôi chỉnh tốc độ baud của HMI là 38400kps sẽ báo lỗi truyền thông ! Nhưng mà tôi chỉnh lại 9600kps thì lại không báo lỗi ?
    Vậy lý do gì mà PLC và HMI không thể truyền thông với nhau ở tốc độ 38400kps ?
