			Tín hiệu analog là dạng tín hiệu vô cùng quan trọng và phổ biến trong các công trình công nghiệp với Siemens và TIA PORTAL các kỹ sư sinh viên có thể xử lý được tín hiệu này trên kia hỗ trợ sẽ không phải viết các hàm các khối dài như các môđun đời cũ của PLC khác hiện nay.Tín hiệu analog đo về có 2 dạng tín hiệu: dòng điện và điện áp . Để xử lý chính xác chúng ta cần hiểu được sơ đồ đấu dây phần cứng của nó
