New entrants in the programmable logic controller (PLC) and programmable automation controller (PAC) market are diversifying the landscape with platforms based on CoDeSys IEC-61131, C/C++ and Python, Control Design reported.
While these new systems offer flexibility in programming languages, their applicability varies. CoDeSys-based solutions are preferable for factory-floor and machine-building projects due to their robust interfacing capabilities, whereas C/C++ implementations are less ideal for industrial applications requiring frequent human interaction.
Notably, hardware innovations such as Raspberry Pi and Arduino are gaining traction, offering unique form factors and versatile programming environments. These platforms, although unconventional, are becoming popular due to their cost-effectiveness and expansive connectivity options, including Ethernet, Wi-Fi and USB.
These microcontroller-based systems display IIoT and edge computing capabilities ideal for industrial automation. For example, the Arduino-based Portenta Machine Control PLC, with its array of digital and analog I/Os and communication ports, presents a comprehensive monitoring and control solution.
However, its minimalistic CoDeSys implementation may pose challenges in human interfacing and troubleshooting. Similarly, Raspberry Pi's 64-bit quad-core processor and support for multiple operating systems, including Windows, make it a versatile option for IIoT systems.
