Abstract: Programmable Logic Controllers (PLCs) are used to control industrial machinery such as AC servos, general-purpose inverters, and sensors. They are widely used in factory automation systems for manufacturing and processing lines, machine tools, and industrial robots. Peripheral units of module type PLC include a variety of products to match the specific requirements from end users, while the proliferation of development resources has be-come an issue. To solve this problem, Renesas overs a peripheral unit platform based on the RX Family, which covers a broad performance range (32MHz to 240MHz) and a multitude of peripheral functions. This helps reduce the amount of development resources needed. For block type PLC, RX64M product provides a one chip solution with large capacity RAM, Ethernet, USB, SDCard I/O integrated, leading to both performance rise and BOM size reduction.

Keywords: PLC, Renesas, RL78, RAM, RX Family.
