Omron CJ2M-CPU32 CPU with built-in EtherNet/IP port CPU Ver.2.1 EIP Ver.2.1

1. Overview of the Omron CJ2M-CPU32

The Omron CJ2M-CPU32 is the performance leader in the Omron CJ2M series. Housed in a compact 90 × 65 × 66 mm body, it integrates a high-speed processor capable of executing 5k-step LD instructions in just 0.04 μs. The system can be expanded to accommodate up to 40 CJ series modules, effortlessly managing 2,560 I/O points. It features a built-in 256k-step program capacity, 448k-word data memory, and 32k-word retentive memory, providing ample space for complex recipes, data logging, and floating-point operations. It also features a USB 2.0 programming port and RS-232C communication ports, enabling one-touch online debugging, remote monitoring, and program upgrades, eliminating the capacity bottlenecks of traditional PLCs.

Motion control has evolved. The CPU32 features four axes of high-speed pulse output, with a single axis speed of up to 1 MHz, supporting linear and circular interpolation and synchronized electronic gearing. Four 1 MHz high-speed counters and interrupt inputs enable seamless length measurement, position capture, and flying shear tracking. A built-in EtherNet/IP port allows direct access to SCADA, MES, and cloud gateways, enabling seamless collaboration among robotics, servo, and vision systems. When used with the CJ series EtherCAT expansion module, servo cycles can be compressed to 1 ms, ensuring millisecond-level accuracy for high-speed production lines in industries such as packaging, lithium batteries, and consumer electronics.
