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.
