Description

Optimizing process throughput in advanced factory automation loops, the Omron CJ1G-CPU45H functions as a highly reliable central processing engine within the SYSMAC CJ1 controller families. It offers rapid-cycle execution speed and robust memory allocations to handle sophisticated motion profile mappings, sequential batching, and high-density industrial control matrices. Designed with a loopless, backplaneless form factor, this CPU mounts directly to adjacent I/O modules to conserve space within high-density control panels.

Key Features

Extensive Program Space: Accommodates complex operational logic with 60 Ksteps of program capacity.
Broad Input/Output Handling: Resolves and executes data mapping for up to 1280 individual local and remote I/O points.
High-Speed Processing: Minimizes sequence scan times with optimized execution of basic and advanced instructions.
Data Storage Flexibility: Features 128 Kwords of system data memory (composed of 32 Kwords of DM and 3 EM banks of 32 Kwords each) for continuous data logging and recipe management.
Dual Built-In Communications: Outfitted with an RS-232C port and a peripheral port for concurrent HMIs, programming terminals, and serial devices.

Applications

Multi-axis pick-and-place packaging systems
Automated raw material batch processing
Automotive assembly cell coordination
Main water supply pumping and treatment panels

Alternative Models & Compatibility

The CJ1G-CPU45H serves as an equivalent direct-drop replacement for legacy CJ1G-CPUxx series units. When replacing non-H series controllers, verify that instruction timing differences are evaluated in your existing CX-Programmer routines. If upgrading to CJ2M controllers, please review memory card type differences (CompactFlash vs. MicroSD) and reconfigure option board allocations accordingly.

Application Pitfalls & Engineering Notes

Because this CPU draws up to 0.91 A directly from the 5 VDC internal system bus, ensure the power supply unit (e.g., CJ1W-PA202) has sufficient remaining overhead to support adjacent high-current analog and communications modules. Avoid placing high-temperature producing modules directly next to the CPU unit to prevent localized heat build-up, which can shorten the operating lifespan of the internal backup battery.

Commissioning & Wiring Tips

Set DIP switches situated behind the front compartment cover prior to mounting. Switch 5, for instance, dictates the RS-232C serial port communication protocols; toggling this switch bypasses standard PLC setup parameters to force the port into direct Host Link (SYSWAY) configuration for easy troubleshooting retrieval. Always verify that the Functional Ground (FG) terminal on the master power supply rack is bonded directly to a low-resistance earth ground to shield the CPU from transient electrical noise.

Installation Guidelines

CRITICAL WARNING

Ensure all main AC and field-side DC power sources are completely de-energized and locked out before inserting or removing the CPU unit from the DIN rail assembly. Attempting live removal will cause permanent chip damage to the CPU bus interface or lead to unpredictable machine behavior.

Align the interlocking plastic connectors on the side of the CPU with those of the adjacent power supply module.

Carefully push the modules together until they click, then secure the yellow locking sliders located at the top and bottom of the unit to lock them together.

Hook the assembly onto the DIN rail, snap it flatly into position, and mount end-plates to secure the rack structure against vibration.

What is the internal 5 VDC bus current consumption of this module?

The module draws 0.91 A from the 5 VDC internal system bus. Ensure your system power supply module has adequate current output capacity to support this draw plus all other connected I/O units.

How do you recover serial communications when standard settings are unknown?

Toggle DIP switch 5 to the ON position. This overrides programmed serial parameters and forces the built-in RS-232C port into default Host Link mode for tool connection.

Can I replace an older CJ1G-CPU45 unit with this H-variant?

Yes, the H-variant is backward compatible. However, verify that high-speed instruction changes or cycle times do not interfere with critical process loops or timing calculations in your CX-Programmer logic.

What memory medium is used for external backups?

The CPU unit includes a dedicated memory slot designed to accept standard industrial-grade CompactFlash cards for backup, data logging, and parameter storage.
