OMRON CJ2M-MD21 CPU Units, Pulse I/O Modules
OMRON CJ2M-MD21 CPU Units, Pulse I/O Modules
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 CJ2M-MD21
• 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.
