Every beneficial, advantageous, and affordable automation solution we develop is based on market analysis and trends. Our engineers take the time to inquire about and get it complete the process sometime recently starting any plan or development. The editor of Automation.com, Bill Lydon, distributed an essay titled “PLC vs. DCS – Competing Process Control Logic” in October of that year. The differences he perceives between the two control platforms are listed below: Book a call with us now:
PLC
Common Applications
Material dealing with, water treatment, motor controls, adjustment of plant operations, air compressor controls, bundling, and other non-core handle capacities are included.
Control Architecture
Loose component architectures in the programming model make it simple to add functions using both hardware and software.
Price
No Significant Difference in opposition to DCS.
Enterprise Interface
The majority of PLC applications are associated with business venture systems for data trade and synchronized operations, catching up to DCS in later a long time.
Asset Management
PLCs are playing catch-up.
APC Advanced Process Control
Adding features and breaking into process control.
Total Production Optimization
Attainable with loosely coupled software additions.
Sensor/Control Network Communications
PLC systems typically use less difficult Foundation Fieldbus and HART interfaces. They frequently use third-party hardware and software, with configuration requiring extra work.
DCS Backbone Network
PLC systems make use of open, published protocols that are intended to handle a variety of applications, including motor control, process, and basic discrete, synchronized motion control. PLC suppliers keep including redundancy options. One Ethernet backbone can be used to connect all control functions (process control, discrete, motion control, safety; etc.)
Skid & Packaged Systems
Vendor of skids provides. Field engineering is typically needed to configure and maintain.
DCS
Common Applications
Core processes (food, pharmaceutical, refining, etc.)
Control Architecture
Model for Configuration HMIs, custom applications, multi-disciplined controllers for logic, sequential, and process control, and business integration on a single platform.
Price
No Significant Difference Competitive with PLC.
Enterprise Interface
Since many years prior, DCS systems have been coordinated into the trade, adjusting to both the Purdue Demonstrate and more recently, the ISA95 standard.
Asset Management
Integrated software ought to be made accessible for all gadgets and resource administration standards.
APC Advanced Process Control
Offer a variety of tools for control loop optimization and more complex substitutes to boost PID control performance.
Total Production Optimization
An emerging role is real-time software modeling and control optimization.
Sensor/Control Network Communications
DCSs have suitable interfaces to various industrial automation networks as well as highly developed and integrated Foundation Fieldbus and HART interfaces.
DCS Backbone Network
Process networks including Foundation Fieldbus and HART as well as PLC-focused networks like DeviceNet, Profibus, and Modbus are connected to controllers in DCS systems, which are connected to the process DCS backbone. Although open networking standard groups like ODVA and PI International have established solutions for their protocols, especially with the push for networked machine safety, DCS systems typically offer backup solutions that are simpler to implement.
