Flagship PLCs with Built-in Multifunctional Ethernet Port
Small, Fast, Flexible:
The CJ2 CPU Units inherit and improve CJ1 features while also adding EtherNet/IP as a standard feature for high-speed, high-capacity Ethernet-based networking.
Features

  1. High-speed, high-capacity EtherNet/IP is built into every model.
  2. The CIP communications protocol is supported for direct access to multivendor devices.
  3. Tag memory provided for easy access from host PCs and PTs.
  4. Even more program memory and data memory.
  5. Superior high-speed control performance: LOAD instructions execute in 16 ns, SINE instructions in 0.59 |is.
  6. The more advanced motion control by the lower cost: Synchronous Unit Operation
  7. Increased I/O throughput speed by Immediate refreshing instructions with direct processing.

This function detects errors in tag memory.

 

 

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.

 

 

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 3.

 

 

Program Error Detection

This function detects errors in programs.

 

Fatal Error Detection

 

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.

 

Fatal Error

System FALS Error Detection (User-defined Fatal Error)

This function generates a fatal (FALS) error when the user-defined conditions are met in program.

 

Detection (Continued from

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.

 

Memory Self-restoration Function

This function performs a parity check on the user program area and self-restoration data.
