Omron CJ2H CPU Processing and Communication

The CJ2H-CPU64 executes the PLC application through its CPU processing engine and communicates with connected devices through supported serial interfaces. The specified 0.016 us minimum basic-instruction execution time applies to the instruction execution layer, while the 100 us overhead value represents CPU processing overhead.

The controller provides 2560 I/O bits and supports 128 cyclic task flags. Function-block capacity is specified at 2048 definitions and 2048 instances. Memory-card capacities of 128 MB, 256 MB, and 512 MB provide removable storage options for applicable CJ2 system configurations.

Serial communication parameters include half-duplex transmission, start-stop synchronization, selectable baud rates from 0.3 kbps through 115.2 kbps, and a maximum transmission distance of 15 m under the specified interface conditions.

Field Installation Guidelines

Install the CPU in the CJ-series PLC rack according to the applicable Omron hardware configuration.
Maintain the specified grounding resistance of less than 100 ohm.
Verify the 5 VDC system supply and the 0.42 A specified CPU current consumption.
Confirm rack configuration and I/O allocation before transferring the application.
Install memory cards only in the configuration and orientation specified by Omron.
Do not remove a memory card while the CPU is performing an active memory operation.
Configure serial communication parameters consistently between the CPU interface and connected equipment.
For communications using the maximum specified 15 m transmission distance, use suitable industrial communication cabling and follow Omron wiring requirements.
Verify firmware and CPU unit compatibility before transferring or restoring a PLC project.
Keep wiring separated from high-energy switching conductors to reduce electrical interference.

Frequently Asked Questions

Q: What supply voltage does the CJ2H-CPU64 use?
A: The supplied specification identifies 5 VDC as the CPU supply voltage and specifies a current consumption of 0.42 A.
Q: How much user memory is provided?
A: The CJ2H-CPU64 provides 50K steps of user memory for PLC application programming within the CJ2H CPU architecture.
Q: What is the basic instruction execution time?
A: The minimum specified execution time for basic instructions is 0.016 us. Actual application scan performance depends on the program and system configuration.
Q: What I/O capacity is specified?
A: The CPU supports 2560 I/O bits. Actual usable I/O capacity depends on the CJ-series rack configuration and installed I/O units.
Q: Which memory-card capacities are supported?
A: The supplied data lists 128 MB, 256 MB, and 512 MB memory cards. Compatibility should be checked against the applicable CJ2H CPU firmware.
Q: What serial communication speed is supported?
A: Selectable baud rates range from 0.3 kbps to 115.2 kbps. The interface uses half-duplex communication with start-stop synchronization.
Q: What is the maximum specified communication distance?
A: The supplied specification gives a maximum transmission distance of 15 m. Cable type, electrical noise, and interface configuration affect practical communication performance.
Q: What grounding resistance is specified?
A: The supplied specification requires grounding resistance below 100 ohm. The installation should follow Omron grounding and wiring requirements for the CJ-series system.
