【Question 1】Do SIS and DCS valves need to be set up separately? Can SIL1 and below be shared? 【Answer】1）Refer to “Design Specifications for Safety Instrumented Systems in the Petrochemical Industry” (GB/T 50770-2013): Measurement and actuators are best set up independently. When control valves are shared, it should ensure thatSIS takes priority. 2）Refer to “Acceptance Specifications … Read more
Industrial control systems generally refer to a variety of control systems, including Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), and Programmable Logic Controllers (PLC), among others. 01 Five-Layer Architecture The classic hierarchical model of industrial control systems in the international standard IEC62264-1 divides typical industrial control systems into five levels based … Read more
In the field of industrial automation, DCS (Distributed Control System) and PLC (Programmable Logic Controller) are the two most common control systems. Although they overlap in certain functionalities, their design philosophies, architectures, and application scenarios differ significantly. This article will detail their differences and help you understand how to choose the appropriate control system. 1. … Read more
Industrial control systems sound impressive, but in reality, they are just a combination of hardware and software aimed at making machines operate according to our intentions. Whenever networks are involved, security issues are always present. Stop clinging to the “five-layer architecture”; today we will explore how many security vulnerabilities are hidden within these seemingly robust … Read more
