Breaking down a machine into systems based on both functionality and resources can simplify design and maintenance, a concept explored in a recent column from
Control Design.
For controls engineers, this approach means that power, pneumatics, motion, communications, alarms, MES feedback and SCADA setups can be modularized, allowing for easier management and reuse of code and hardware configurations.
The concept of using open programmable logic controllers (PLCs) to standardize utility handling across different machine builds is highlighted as a way to streamline the process. This modularization extends to the functionality of the machines, facilitating templated solutions that can be applied consistently.
Furthermore, the article explores the evolution of control systems from traditional relay-based setups to modern, edge computing and Industrial Internet of Things (IIoT) driven environments. It discusses how the rise of Industry 4.0 is transforming PLC-oriented control systems by integrating advanced computing and artificial intelligence, reducing the PLC's role as instrumentation is managed remotely.
