Omron CJ1M-CPU23 Ver. 3.0 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
Omron CJ1W-DRM21 CJ-series DeviceNet UnitFeaturesAllows control of up to 32,000 points (2,000 words) per master, and ensures a high degree of simultaneity between data.Can be used as both a master and a slave at the same time.Equipped
with settings and monitor functions aimed at improving both design and
startup efficiency. Achieve maximum performance by using in combination
with a Configurator.Files of master and slave settings can be
uploaded and downloaded using memory cards, allowing effective debugging
and easier setup.

Omron CJ1W-ETN21 ver. 1.3 CJ-series Ethernet UnitTestedFeaturesUse Ethernet to implement various communications protocols.Implement
FINS message communications using UDP/IP or TCP/IP with a user
application on a host computer or with Support Software, such as the
CX-Programmer.Use the clock on an SNTP server to automatically
adjust the clocks in the PLCs connected to the Ethernet network. (An
SNTP server is required separately.)An FTP server is built in,
so files can be used to transfer PLC data between network PLCs and
workstations or personal computers with an FTP client.Email can
be used to send commands to the PLCs, or triggers can be set so that
the PLCs will send PLC data or Ethernet Unit status to a host computer.The
standard UDP/IP and TCP/IP protocols are supported to enable
communications with a wide range of devices, workstations, personal
computers, and Ethernet modules from other manufacturers.The SMTP/POP3/SNTP servers enable the use of host names instead of IP addresses. (A DNS server is required separately.)
