Age-old batch and continuous processes that involve manual intervention and data logging are being phased out by newer tech like real-time monitoring with IoT. A key part of this step-up is distributed control systems (DCS) that connect multiple industrial processes and enable automation.
Modern industrial processes call for enhanced process control in a manner that is seamless, safe, scalable, and reliable. Only by integrating individual system components with platforms such as IoT and implementing centralized automation can modern industries be future-proofed. The cornerstone of enabling seamless process automation, integration, and more is the Distributed Control Systems (DCS).
Let’s check out exactly how the distributed control system by ABB, a leading automation parts distributor, enhances efficiency, reliability, and operational control.
Understanding Distributed Control Systems (DCS): What Is a DCS and How Does It Work?
Distributed Control Systems, or DCS, are computerized systems that are at the center of industrial operations. They provide top-down control and coordinate with the various sub-processes in an industrial system (both batch and continuous) in real-time.
The core components of a DCS system are controllers, operator stations, and communication networks.
Unlike centralized systems, where the main server manages all aspects of the system, DCS are made of several interconnected systems. This makes the industrial system more resilient, scalable, adaptable, and potentially better performing.
The question is this: how does it differ from PLCs?
The answer: PLCs work on a smaller scale, i.e., they are capable of handling one to a small number of industrial processes. Though they are getting an increasingly sophisticated design, are rugged, and designed for industrial extremes, they do not have the scalability or capacity to run an entire plant. This is where DCS comes in.
Comparison with Other Automation Solutions: ABB DCS vs Other PLC Systems and SCADA
The key differences between DS, PLC, and SCADA can be better explained with the help of the following table:
| System | What it Involves | Advantages | Disadvantages |
| ABB DCS | Data acquisition and storing, system security and diagnostics, device control, and alarms | Offers data storage, system redundancy, preemptively prevents overloads, processing, and provides preventive maintenance | Expensive, high maintenance requirements, needs regular software and hardware upgrades |
| PLC | Takes input data (signals) from connected field devices and sends outputs (to actuators) to implement process control | High reliability, low maintenance requirements, easy to troubleshoot, and quick response times | Lacks modularity |
| SCADA | Receive and process data from field devices, offer an HMI, and proprietary protocols to enable smooth data transfer | Provides real-time access to data, alongside remote access and trend monitoring for better analytics and efficiency | Requires a high skill level, may have compatibility issues |

Common Pitfalls to Avoid
Further, be sure to watch out for the following pitfalls when it comes to installing a fresh DCS system:
- Poor pre-integration planning.
- Not accounting for the exact industrial requirements.
- Neglecting cybersecurity measures.
- Not regularly opting for software and hardware updates.
DCS Implementation Checklist: Do’s and Don’ts to Follow
Some of the do’s and don’ts to account for before installing a DCS are
| Do’s | Don’ts |
| ● Define the scope of work for the DCS. ● Choose a technology that aligns with your needs. ● Opt for a robust system. ● Ensure that it offers the necessary security controls. ● Test for functionality and performance. ● Document all configuration changes. ● Involve the end users in the process. ● Monitor and optimize the DCS as required. ● Ensure regular data backup to prevent loss. | ● Overlook scalability in favour of other factors. ● Ignore training the end-users. ● Rush through the installation process. ● Cut corners on testing during implementation. ● Make the DCS an isolated system. ● Assume that the installed DCS will be compatible with legacy systems. ● Ignore cybersecurity measures that protect the system. ● Fail to plan for regular maintenance. |
