Omron: Modular PLC (CJ2M Series)

CJ2M for basic machine automation

The CJ2M Series is ideal for packaging and general machine automation needs. Connectivity is assured thanks to the built-in USB port and the choice of Ethernet and RS-232C/422/485 interfaces on the CPU.

  • Always accessible through standard USB port

  • Standard Ethernet port with EtherNet/IP Data Link function

  • Wide range of program capacities from 5K steps to 60K steps

  • Serial option board

  • Dedicated function block memory ensures efficient execution of function block software modules

CJ-Series Power Supplies, Expansions

Power and flexibility

CJ systems can operate on 24 V DC power supply, or on 100 - 240 V AC mains. For small-scale systems with mainly digital I/O a low-cost small-capacity power supply can be used. For systems with many analog I/Os and control/communication units, it may be necessary to use a larger power supply Unit.

Depending on the CPU type, up to 3 expansions can be connected to the CPU 'rack', giving a total capacity of 40 I/O units. The total length of the expansion cables of one system may be up to 12 m.

CJ-Series Digital I/O Units

8 to 64 points per unit - input, output or mixed

Digital I/O units serve as the PLC's interface to achieve fast, reliable sequence control. A full range of units, from high-speed DC inputs to relay outputs, let you adapt CJ1 to your needs.

CJ units are available with various I/O densities and connection technologies. Up to 16 I/O points can be wired to units with detachable M3 screw terminals or screwless clamp terminals. High-density 32- and 64- point I/O units are equipped with standard 40-pin 'flat cable'-connectors. Prefabricated cables and wiring terminals are available for easy interfacing to high-density I/O units.

CJ-Series Analogue I/O and Control Units

From basic Analogue I/O to advanced temperature control

CJ offers a wide choice of analogue input units, fit for any application, from low-speed, multi-channel temperature measurement to high-speed, high-accuracy data acquisition. Analogue outputs can be used for accurate control or external indication.

Advanced units with built-in scaling, filtering and alarm functions reduce the need for complex PLC programming. High-accuracy process I/O units support an extensive range of sensors, for fast and accurate data acquisition. Temperature Control units relieve the PLC CPU of PID calculations and alarm monitoring. These functions are handled autonomously by the unit, offering control performance and autotuning functions similar to stand-alone temperature controllers.

CJ-Series Position / Motion Control Units

Add motion control to any CJ-Series PLC

From simple position measurement to multi-axis synchronized motion control, CJ-Series offers a full range of units:

  • Counter Units gather position information from SSI- or incremental encoders. Actual positions are compared with internally stored target values.

  • CJ2M CPU Units have dedicated positioning functions that can be used by installing up to 2 Pulse I/O option modules.

  • Position- and Motion Control Units equipped with EtherCAT, can control multiple drives through a single high-speed link. Message routing through multiple communication layers allows the attached drives to be configured from any point in the control network.

CJ-Series Communication Units

Open to any communication

The CJ-Series provides both standardized open networks interfaces, and cost-efficient high-speed proprietary network links. Datalinks between PLCs, or to higher-level information systems can be made using Serial or Ethernet links, or the easy-to-use controller Link network.

Omron supports the 2 major field networks, DeviceNet and PROFIBUS-DP. For high-speed field I/O, Omron's own CompoBus/S offers an unsurpassed ease of installation. Fully user-configurable Serial and CAN-based communication can be used to emulate a variety of application-specific protocols.

EtherNet/IP units provide data link functions to share large amounts of data between PLCs. The new PROFINET-IO controller together with the SmartSlice modular I/O system offers ethernet-based I/O with controller- and network redundancy.

CJ-series I/O Modules - HighSpeed Counting

Detect high-speed machine or process motion for positioning

CJ-Series High-Speed Counter module accepts input pulse frequencies that allow precise control of fast machine motion. Each bidirectional counter can be configured independently as a simple counter, circular counter, or linear counter according to the application.

  • 2 digital inputs, 2 digital outputs and 30 soft outputs

  • 50 kHz counting with open collector voltage input

  • 500 kHz counting with RS-422 line driver

  • Maximum response time of 0.5 ms guarantees high-speed closed loop control of applications
