Configured for high-speed sequence processing and high-density logic execution in CS1 Automation Systems, the Omron CS1H-CPU67H (CS1H-CPU67H CPU Unit) provides direct physical/electrical execution.

Model Nomenclature Breakdown

• CS1H System Architecture: Denotes high-performance CPU processing unit designed for CS1 backplane racks.
• CPU67 Memory Capacity: Identifies maximum program capacity allocation supporting 250k steps and 448k words of data memory.
• H Processing Variant: Represents high-speed execution engine with accelerated instruction execution times.

Mechanical and Electrical Specifications

Backplane Velocity and Execution Engine Dynamics

The unit features a dedicated internal processing architecture optimized for deterministic program execution and backplane bus communication velocity. High firmware flash compatibility allows synchronous data exchange across multi-rack expansion configurations without causing CPU scan overhead. Direct execution logic handles high-volume instruction routines while maintaining tightly governed task execution cycles across complex automation networks.

Included Package Components

• 1 x Omron CS1H-CPU67H CPU Unit
• 1 x System Battery (CPM2A-BAT01 / CJ1W-BAT01 pre-installed or enclosed)
• 1 x Operating Manual Insert

Cabinet Installation & Wiring Directives

• Power Interruption Requirement: Ensure all primary rack power supplies are completely isolated before mounting or dismounting the CPU unit.
• Mechanical Latching: Align the CPU module guide rails with the backplane slot and press firmly until the locking levers snap into position.
• Grounding Considerations: Connect the protective earth (PE) terminal on the power supply unit to a dedicated ground system using minimum 2 mm2 copper wire to minimize high-frequency noise.
• Serial Port Shielding: Ensure communication cables connected to the built-in RS-232C port use shielded twisted-pair conductors with grounded outer braiding.

Hardware Technical Q&A

• Can the CS1H-CPU67H module be swapped out while the backplane power supply remains turned on?

  No, the CPU unit requires complete de-energization of the backplane rack prior to physical removal or insertion.

• How is the user program retention maintained during an extended system power-off state?

  Program and data memory are maintained by an internal lithium backup battery mounted behind the front compartment cover.

• What current load does the CPU unit draw from the internal rack backplane logic bus?

  The processor draws 0.82 A at 5 VDC directly from the internal logic supply rail of the backplane.

• What interface cables are supported on the primary built-in peripheral port?

  The peripheral port connects directly to programming devices or host computers via CS1W-CN226 or CS1W-CN626 dedicated programming cables.

• How are system fault conditions diagnosed locally on the module front panel?

  Status indicators including RUN, ERR/ALM, INHC, and PRPH/COMM provide real-time operational status and hardware fault indications.

• Is expansion memory supported on the CS1H-CPU67H CPU processor?

  Yes, memory cards (Flash Memory or Memory Cards) can be installed in the dedicated slot to store backup programs and data files.

• Does the CPU unit support multi-rack expansion hardware layouts?

  Yes, the processor manages local expansion racks connected via CS1W-IC102 or CS1W-II102 expansion interface modules.

• How is the inner memory cassette backed up against data corruption?

  Program files can be transferred to non-volatile flash memory or stored on a Memory Card via execution from CX-Programmer.
