Omron CJ1M-CPU23 Ver. 4.0 CJ-series PLC CPU Unit
Number of I/O points - 640
Maximum number of Expansion Racks - 1 Rack
Maximum number of connectable Modules - CPU Rack: 10 Modules, Expansion Rack: 10 Modules
Program capacity 20 Ksteps
Data memory capacity 32Kwords (DM only, no EM)
LD instruction processing speed - 100 ns
Buit-in ports - Peripheral and RS232C port
Mountable options - Memory Card (compact flash)
Built in I/O - 10 inputs and 6 outputs
Inputs: 4 interrupt inputs (pulse catch); 2 high-speed counter inputs (Phase differential: 50 kHz; Single phase: 100 kHz) Outputs: 2 pulse outputs (2 points for positioning, 100-kHz speed control, and PWM output)
Same instruction set as the more powerful CJ1G/H
Completely compatible with all CJ1 I/O
Up to 64 MB flash memory available for many timesaving programming uses
Serial PLC Link allows simple communication among 9 CJ1 PLCs (1 master, 8 slaves)
A pulse I/O instruction takes advantage of positioning capabilities in the CPU22 and the CPU23
Easy terminal block connection for built-in I/O (CPU22 and CPU23)
CPU22 and CPU23 have built-in pulse catch inputs which will detect pulses that are quicker than the CPU cycle time
