Configuration implementation considerations for distributed control systems

There are many manufacturers that have designed and built distributed control systems (DCSs) and there are several methods that can be performed to make the plant implementation process more efficient.

Once the necessary research and proper investigation of interface circuitry for field instruments is done, the configuration process is more reliable and cost-effective for the client-especially during a plant turnaround with time restraints. Courtesy: MaThere are many manufacturers that have designed and built distributed control systems (DCSs) with a large selection of features and enhancements to choose from. No matter what the control systems platform's structure is the tag name/point name implementation methodology is basically the same. There are some things that can be done before the actual plant implementation is done onsite to make this process more efficient. Once the necessary research and proper investigation of interface circuitry for field instruments is done, the configuration process is more reliable and cost-effective for the client-especially during a plant turnaround with time restraints.

The control systems engineer is familiar with the software connections and the main DCS parts through the control system configuration. To understand what type of devices an engineer will be interfacing with, the following considerations are noted:

These are some of the basic configuration parameters that are used no matter what DCS platform is been used. Keep in mind that a particular control system will have similar descriptions, but in principle, they convey the same information.
