The E33NRHA-LNN-NS-00 can enhance process manipulation in a variety of ways. The fundamental PID control algorithm of the new automation system is more refined than that of the previous system, and the response speed is faster, which can improve the control of all the normal PID circuits. The self-tuning of the PID loop is generally built-in, which then provides better initial values for the tuning parameters, and also facilitates continuous adjustment and improvement.

In addition to the basic PID algorithm, the modern automation system includes other conditioning control options, such as enhanced PID and user-defined instructions. The enhanced PID uses the speed algorithm of the PID equation, that is, the loop is changed by deviation to change the output. User-defined instructions (custom instructions created by users) are used to encapsulate commonly used functions or device controls.

The new automation system also has built-in advanced process control (APC) functions such as model-based functional blocks and fuzzy logic. These features can be used to create a user's own APC application. The key components of these tools are canonical custom functional blocks that can be interlinked in a variety of ways to develop APC applications. The combination of specification and custom APC functional blocks allows users to control loops that cannot be conditioned to an acceptable level by a simplified PID or other conditioning control methods (e.g., enhanced PID or user-defined instructions).

Compared with the previous DCS, the new automation system has enhanced alarm and event processing functions. This improves operator performance and provides more valuable data to engineers responsible for plant operational profiling and performance improvement.

Improvements to alarm handling include the ability to prioritize alarms, then reduce the number of alarms and make it easier to determine the root cause of alarms. Factory personnel can use time-stamped alerts and event detailed lists to parse process disturbances and other anomalies. With such profiling, root causes can be identified more quickly and maintenance personnel can correct problems at the source.

The new automation system also allows non-programmers to create reports that provide data in an easy-to-understand format. Simple, easy-to-understand reports help you better understand plant performance and improve operations. It is generally not easy to create reports using previous DCS.

In terms of performance, compared with the previous DCS, the new automation system can reduce the occurrence of faults. In addition, vendors are constantly adding new features and capabilities to their automation system products, and these additions (especially software-related upgrades) are often available or even free of charge.
