Vùng nhớ thanh ghi bit đặc biệt trên plc delta

 

Tác dụng của vùng nhớ thanh ghi bit đặc biệt trên plc delta

Giống như các hãng plc khác thì Delta cũng cung cấp cho người lập trình viên plc một số vùng nhớ thanh ghi bit đặc biệt quy định một chức năng cụ thể để có thể sử dụng trong quá trình viết chương trình. Thường thì vùng nhớ, thanh ghi, bit đặc biệt này sẽ nằm trong vùng nhớ M và D nên các bạn cần chú ý không sử dụng hai vùng nhớ vượt quá giới hạn để tránh bị trùng chéo lên vùng đặc biệt làm ảnh hưởng đến giá trị tính toán trong khi lập trình.

Đối với mỗi dòng plc delta khác nhau thì sẽ hỗ trợ vùng nhớ thanh ghi bit đặc biệt khác nhau do sự khác nhau của tập lệnh, các bạn tham khảo chi tiết trong manual của từng dòng để biết chính xác địa chỉ của vùng nhớ thanh ghi và bit đặc biệt này.
