DCS and PLC have been competing for 40 years, let’s take a look at the differences and applications first!
The topic of DCS and PLC has been debated in the industry for at least 40 years. To understand what everyone is debating, it is necessary to understand the differences between DCS and PLC, objectively understand these fundamental differences, and rationally choose to apply DCS and PLC based on products and needs. 1. DCS focuses…
What is the difference between DCS system and PLC control system?
1. What is the difference between DCS system and PLC control system? DCS tends to control a large number of circuits and is widely used in large-scale control in the process industry, characterized by a large processing capacity. PLC was developed from relay circuits, while DCS was developed from local instrument screens. With the development…
PLC和DCS控制系统有何区别
01 The origin is different. PLC is born for discrete sequential control. We first developed a generation of programmable controllers using relay control devices. With the development of integrated circuit technology and computer technology, there are now five generations of PLC products. DCS was born for continuous process control. It is based on microcomputer processing,…
Eight essential martial arts and mental techniques for advanced appearance skills
Safety is something that every chemical instrument operator must always bear in mind! In chemical production, various materials often undergo various forms of physical or chemical changes in a liquid or gas state, continuously in closed containers and equipment, under different conditions such as high temperature, high pressure, and deep freezing; In addition, many media…
Do you know about the release of safety related standards for these functions?
Background: The System and Functional Safety Subcommittee SC10, under the National Standardization Technical Committee for Industrial Process Measurement and Control (SAC/TC124), actively establishes China’s own functional safety technical standard system, promotes the further implementation of functional safety/SIS related technologies in the process industry, and improves the level of safety control in the process industry. After…
Smart oilfield, lightning protection solution on oil and gas pipelines
The petroleum and petrochemical industry plays a crucial role in the development of the national economy. As one of the pillar industries in China, the production process involves a wide range, including oil extraction engineering, petroleum refining, oil and gas transportation, and so on. With the promotion of policy support and energy transformation needs, modern…
The difference between SIS and ESD, DCS, PLC
SIS：Safety Interlocking System（Safety Instrument Syetem）； ESD：Emergency Shutdown System ； DCS：DistributedControlSystem； PLC：Programmable Logic Controller ； SIS is a safety instrument system, ESD is an emergency stop system, and ESD is a part of SIS. SIS includes three parts: on-site instruments, logic solvers, and actuators, all of which are designed for safety. Conventional ESD systems are only…
CPCI-680 Magnetic Design of Giant Magnet Resistance Multi coil Position Sensor
Multi turn sensors essentially combine magnetic write and electronic read memory with traditional magnetic angle sensors to provide high-precision absolute positions. The magnetic writing process described in “Multi turn Position Sensor (TPO) with true power on capability and zero power consumption” requires the use of specific operating windows to maintain the incident magnetic field. If…
0504994880 Good supply chain management starts with research and development selection
And this involves supply chain management issues. In the electronics industry, supply chain management runs through the entire process of product selection, design scheme, trial production, mass production, etc., which will directly affect the development efficiency and competitiveness of products. If supply chain management is done well during the product development and selection stage, it…
