What is the role of control logic in an automation system?

Control logic is fundamental to automation systems because it defines the operational rules and conditions under which the system operates. This includes specifying how different components of the system should behave in response to various inputs and changes in process variables. By establishing these rules, control logic ensures that processes run efficiently and in a controlled manner, aligning with desired specifications and performance criteria. It dictates how the system should respond to different scenarios, such as normal operational states, alarms, and fault conditions, thereby providing a framework that governs the interactions between various elements of the automation system.

In automation systems, safety protocols are important, but they are often a subset of the broader operational rules defined by control logic. Data logging functions, while essential for monitoring and analysis, are more about collecting information than controlling system operations. Similarly, enhancing user experience in Human-Machine Interfaces (HMIs) is valuable for interaction with the system, but it does not directly relate to the fundamental functioning dictated by control logic.
