What specifications are available for reference when participating in the design of DCS configurations?

I need help: what specifications can be referred to when participating in the installation team to configure a pilot-scale platform? Thank you
Software configuration does not require reference to specifications; whereas for hardware design, it is necessary to follow the design specifications for distributed control systems. It also depends on the industry – is it chemical engineering or metallurgy? Or is it some other industry? The standards in the petrochemical sector are higher; you need to be clear about that. You can refer to SH3092-2013, the Design Specification for Distributed Control Systems in Petrochemical Industries. For the software configuration, you simply need to implement the functions as specified in the design drawings provided by the design institute, such as interlock logic, alarm setpoints, and automatic control loops.
HG/T 20573-2012 Design Specifications for Distributed Control System Engineering; HG/T 20700-2014 Design Specifications for Programmable Controller System Engineering; HG/T 4599-2014 General Technical Requirements for the Configuration of Instrumented Distributed Control Systems in Chemical Plants; SH/T 3092-2013 Design Specifications for Petrochemical Distributed Control Systems
First, one must become familiar with the process flow and control procedures; this involves thoroughly understanding PID diagrams, logic diagrams of instrument interlocks, instrument loop diagrams, and lists of instruments. Next, one must master both the hardware and software of the DCS being used. Typically, DCS configuration consists of three main components: hardware configuration, network configuration, and configuration of user control programs.
