What are the main components of a typical Rockwell Automation control system?

A typical Rockwell Automation control system is fundamentally composed of a programmable logic controller (PLC), various input/output (I/O) modules, software such as RSLogix and FactoryTalk, and Human-Machine Interface (HMI) systems. The PLC serves as the brain of the control system, responsible for executing control logic and managing the operation of the entire system. I/O modules are essential for interfacing between the PLC and the physical world; they convert sensor signals into data that the PLC can process and vice versa.

The software components, particularly RSLogix for programming and FactoryTalk for visualization and monitoring, are integral as they provide the tools needed for control logic development and system management. The HMI allows operators to interact with the control system, providing a user-friendly interface to monitor and control processes.

In contrast, the other options address components outside the core Rockwell Automation control system. While PCs, network switches, and servers can provide supportive infrastructure, they do not specifically form the main control system itself. Robots, conveyors, and production lines are related to automation but do not represent the control system's components directly. Lastly, raw materials, finished goods, and logistics pertain to supply chain management rather than control system structure. Thus, option B
