Sharp JW-22CU Programmable Logic Controller CPU Module

Sharp JW-22CU is a CPU module in Sharp’s JW20H series of programmable logic controllers, serving as the central processor for a JW-series PLC setup and coordinating logic execution with attached I/O modules through a built‑in communications port designed for inter-unit JW-series networking. It supports up to 512 input/output points and offers a programming capacity of up to 7.5K words, enabling mid‑scale automation tasks when paired with compatible memory units such as RAM JW-21MA and EEPROM/EPROM options. As a CPU module, the JW-22CU is intended to be used in a JW-series control rack alongside memory and I/O boards to form a complete automation system. Programming and configuration are commonly performed with JW‑300SP software over RS‑232C using a PC, with typical connection settings referenced in Sharp’s JW-series guidelines (for example, 19200 baud, 7 data bits, even parity, 1 stop bit). The JW-22CU is designed to support inter‑device communication within the JW ecosystem, enabling coordinated control across multiple CPUs and peripherals in industrial environments.
