Product Description

Omron CJ-series CJ2M CPU Units Pulse I/O Modules CJ2M-CPU31 32 33 35 CJ2M-CPU11 CJ2M-MD211

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.

Battery Error Detection This function detects an error when a battery is not connected to the CPU Unit or when the battery voltage drops.
CPU Bus Unit Setting Error Detection This function detects an error when the model of a CPU Bus Unit in the registered I/O tables does not agree with the model that is actually mounted in the PLC.
Special I/O Unit Setting Error Detection This function detects an error when the model of a Special I/O Unit in the registered I/O tables does not agree with the model of Unit that is actually mounted.
Option Board Error Detection *13 This function detects the errors in Serial Option Board mounting status.
Fatal
Error
Detection		 Memory Error Detection This function detects errors that occur in memory of the CPU Unit.
I/O Bus Error Detection This function detects when an error occurs in data transfers between the Units mounted in Rack slots and the CPU Unit and detects when the End Cover is not connected to the CPU Rack or an Expansion Rack.
Unit/Rack Number Duplication Error This function detects an error when the same unit number is set for two or more Units, the same word is allocated to two or more Basic I/O Units, or the same rack number is set for two or more Racks.
Too Many I/O Points Error Detection This function detects an error when the total number of I/O points set in the I/O tables or the number of Units per Rack exceeds the specified range.
I/O Setting Error Detection This function detects an error when the number of Units in the registered I/O tables does not agree with the actual number of Units that is mounted, or an Interrupt Unit has been connected in the wrong position, i.e., not in slot 0 to 4.
Program Error Detection This function detects errors in programs.
  Instruction
Processing
Error Detection		 This function detects an error when the given data value is invalid when executing an instruction, or execution of instruction between tasks was attempted.
Indirect DM/EM
BCD Error
Detection		 This function detects an error when an indirect DM/EM address in BCD mode is not BCD.
Illegal Area
Access Error
Detection		 This function detects an error when an attempt is made to access an illegal area with an instruction operand.
No END Error
Detection		 This function detects an error when there is no END instruction at the end of the program.
Task Error
Detection		 This function detects an error when there are no tasks that can be executed in a cycle, there is no program for a task, or the execution condition for an interrupt task was met but there is no interrupt task with the specified number.
Differentiation
Overflow Error
Detection		 This function detects an error when too many differentiated instructions are entered or deleted during online editing (131,072 times or more).
Invalid
Instruction Error
Detection		 This function detects an error when an attempt is made to execute an instruction that is not defined in the system.
User Program
Area Overflow
Error Detection		 This function detects an error when instruction data is stored after the last address in user program area.
Cycle Time Exceeded Error Detection This function monitors the cycle time (10 to 40,000 ms) and stops the operation when the set value is exceeded.
System FALS Error Detection (User-defined Fatal Error) This function generates a fatal (FALS) error when the user-defined conditions are met in program.
Version Error Detection This function detects an error when a user program includes a function that is not supported by the current unit version.
Memory Card Transfer Error Detection This function detects an error when the automatic file transfer from Memory Card fails at startup.
Main-
tenance		 Simple Backup Function This function collectively backs up the data in CPU Unit (user programs, parameters, and I/O memory) and internal backup data in the I/O Units.
Unsolicited Communications A function that allows the PLC to use Network Communications Instruction to send required FINS commands to a computer connected via a Host Link
Remote Programming and Monitoring Host Link communications can be used for remote programming and remote monitoring through a Controller Link, Ethernet, DeviceNet, or SYSMAC LINK Network. Communications across network layers can be performed.
Controller Link or Ethernet: 8 layers
DeviceNet or SYSMAC LINK: 3 layers
Automatic Online Connection via Network Direct Serial
Connection		 This function enables automatically connecting to the PLC online when the CX-Programmer is directly connected by a serial connection (peripheral (USB) port or serial port).
Via Networks This function enables connecting the CX-Programmer online to a PLC that is connected via an EtherNet/IP network.
Security Read Protection using Password This function protects reading and displaying programs and tasks using passwords.
Write protection: Set using the DIP switch.
Read protection: Set a password using the CX-Programmer.
FINS Write Protection This function prohibits writing by using FINS commands sent over the network.
Unit Name Function This function allows the users to give any names to the Units. Names are verified at online connection to prevent wrong connection
Hardware ID Using Lot Numbers This function sets operation protection by identifying hardware using the user programs according to lot numbers stored in the Auxiliary Area.
