SYSMAC CJ-series CJ2M CPU Units CJ2M-CPU3@/-CPU1@ CSM_CJ2M-CPU3__-CPU1_DS_E_1_2 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 units on 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 • User-friendly programming, faster debugging CJ2M-CPU3@ CJ2M-CPU1@ 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. 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. 1 CJ2M-CPU3@/-CPU1@ Ordering Information International Standards • The standards are abbreviated as follows: U: UL, U1: UL (Class I Division 2 Products for Hazardous Locations), C: CSA, UC: cULus, UC1: cULus (Class I Division 2 Products for Hazardous Locations), CU: cUL, N: NK, L: Lloyd, and CE: EC Directives. • Contact your OMRON representative for further details and applicable conditions for these standards.

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. 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 Security This function detects errors in programs. 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. 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.
