SYSMAC CJ-series CJ2M CPU Units, Pulse I/O Modules

CJ2M-CPU3

/-CPU1

/-MD21

Since 2001, CJ1M-series PLCs are in

control of a wide variety of

applications worldwide.

The accumulated experience and

advancements in technology now

result in CJ2M; fully compatible, yet

fully new.

• Increased performance, and increased memory capacity

• Up to 40 I/O unit on any CPU

• Pulse I/O Modules add position control functions to any CPU

• USB for plug-and-play access to the PLC

• All models available with or without Ethernet port

• Choice of serial port plug-in modules

Features

• Five variations in program capacity from 5K steps to 60K steps; scale the CPU to your application needs.

• Faster processors; LD instruction execution time is reduced to 40 ns, floating point trigonometrics in less than 1 μs.

• Optional Pulse I/O Modules can be mounted to enable positioning functions for up to four axes. The module provides high-speed counters,

interrupt inputs and pulse train/PWM outputs. (CJ2M CPU Units with Unit Version 2.0 or Later)

• Faster Function Block calls and execution, faster interrupt handling, less overhead time.

• Added execution memory for Function Blocks allows structured, object-oriented programming even in entry-level CPUs.

• General-purpose Ethernet port supports EtherNet/IP tag-based data links, connection to Support Software, communications between PLCs,

FTP data transfers, and more (CJ2M-CPU3@).

• Standard USB port on all models allows Support Software to connect directly through standard USB cable.

• A Serial Option Module can be mounted to add RS-232C or RS-422A/485 communications ports (CJ2M-CPU3@).

• Compatible with all existing CJ1 power supply-, I/O-, control- and communication units.
