5. Taswirar Fasaha: Jagorar Haɗa Tsarin Mataki Zuwa Mataki
Nasarar haɗa tsarin tana bi hanya mai tsari. Bisa gogewar ayyuka, ga muhimman matakai:
- Mataki na 1 – Lissafi & Duban Dacewar Kayan Aiki: Yi lissafin dukkan nau’in PLC (Rockwell, Siemens, Schneider) da nau’in DCS (ABB, Emerson, Yokogawa). Duba irin ladabbin sadarwa (protocols) da suke goyon baya (Modbus TCP, Profinet, EtherNet/IP, OPC DA/UA).
