What is the difference between the SCDAD system and the DCS system?
Thread Content
Solve? As far as we know, many facilities use this SCDAD system, while DCS is more commonly used in refining and petrochemical industries. So what are the differences between these systems? And what is the relationship with other control systems such as Zhejiang University’s Zhongkong? Thank you.
The SCDAD system focuses on data collection, with control being secondary； The focus of the DCS system is control.
Well, SCADA can be considered a part of DCS.
DCS is a distributed control system, focusing primarily on control. SCADA stands for Supervisory Control and Data Acquisition, with a focus on data acquisition. The ECS100\ECS700 products from Zhejiang University Zhongkong are hardware devices; they can be referred to as DCS or SCADA. Here we call it SCADA, using the ECS700. In some devices, what is used is called DCS; it’s also ECS700.
SCADA systems are primarily used in oil and gas field projects, and are suitable for long-distance pipelines and stations. The field controllers consist of PLCs and RTUs, etc., and are mainly used for data collection, switch control, scheduling management, etc. DCS focuses on PID control, sequential control, complex control, etc
DCS: distributed control system; SCADA: supervisory control and data acquisition system. DCS is primarily used in installations for controlling processes such as single-loop, cascade, batch, and segmented control； SCADA is primarily used for the control of long-distance pipelines, oil and gas fields, as well as valve rooms; the controllers include PLCs and valve room RTUs, and its main functions are data collection, switch control, and scheduling management
