Regarding DCS maintenance issues
Thread Content
What level is required for DCS maintenance work, and which specific DCS technologies need to be mastered?
Very skilled in local area networks, and expert at DCS programming.
One needs to have strong logical skills; at the very least, they should be familiar with the production process.
One must be proficient in computers, familiar with network structures and principles, understand the workings of DCS systems as well as the types of signals used in automation systems. It is necessary to have a thorough understanding of the functions of all the hardware components of the DCS being maintained, as well as the interface operations of its software – this includes creating logic diagrams and configuring control strategies, drawing flowcharts, and performing tasks such as loading and backing up files. In addition, it is important to know the key aspects of daily maintenance and repair of DCS systems.
One must be proficient in networking, logic, engineering, and computers
DCS technology involves the “4C”: Computer, Communication, Display (CRT), and Control. Computers: Involves hardware knowledge (basic concepts and knowledge of analog circuits, installation, maintenance), as well as software knowledge (knowledge of digital circuits, programming languages, and good programming habits). Communications: Primarily involves basic communication concepts. Control: Mainly relates to theories of automatic control and self-regulation ；
