The Omron CS1H-CPU65H, also cataloged as the CS1H-CPU65H CPU Processor, operates as a dedicated hardware component for high-speed program execution and system I/O scanning within SYSMAC CS1H PLC architectures.

System Variant Breakdown

• CS1H Product Class: High-performance CPU architecture engineered for large-scale industrial control configurations.
• CPU65 Capacity Level: Standardized memory mapping providing 60 Ksteps of instruction space and 128K words of data memory.
• H Processing High-Speed Subsystem: Advanced processor core capable of 0.02 us BASIC/LD instruction processing speeds.

Physical and Electrical Specifications

Deterministic Execution and Backplane Velocity

The module incorporates high-speed logic execution handling to maximize backplane bus communication velocity across local and expansion racks. Firmware flash compatibility ensures synchronized cyclic scanning, enabling extensive I/O density scaling up to 5120 points without introducing instruction timing jitter during complex arithmetic calculations.

Rack Mounting and Hardware Guidelines

• Power System Isolation: Always disconnect primary AC power from the rack power supply unit prior to inserting or removing the CPU module from the base plate.
• Mechanical Latching: Seat the processor fully into the CPU slot and lock the top and bottom retention levers to secure structural and electrical ground bonds.
• Port Strain Relief: Secure RS-232C and peripheral interface cables to structural panel clamps to prevent physical strain on internal solder joints.
• Ambient Thermal Control: Maintain a 50 mm vertical clearance above and below the rack assembly to facilitate natural convective cooling.

Frequently Asked Questions

• Is hot-swapping permitted for the CS1H-CPU65H unit on active backplanes?

  No, removing or inserting the CPU processor while the system is energized disrupts backplane bus logic and causes immediate CPU stop faults.

• How does the unit maintain program memory during external power outages?

  An onboard lithium battery provides continuous backup power to maintain user RAM and clock registers when primary power is removed.

• What supplies operating current to the CPU module?

  The processor draws 1.10 A at 5 VDC directly from the internal backplane bus powered by the primary rack power supply module.

• What maximum expansion rack limit applies to this CPU configuration?

  The unit supports connection to a maximum of 7 expansion racks using dedicated CS1 expansion bus cables.

• What status is indicated by a solid red ERR/ALM LED?

  A solid red light indicates a fatal hardware or memory execution error that immediately halts program execution.

• Can the RS-232C port operate simultaneously with the peripheral port?

  Yes, both integrated ports function independently for concurrent peripheral tool connections and host link communications.

• How is I/O density scaling managed across expansion racks?

  The processor automatically maps physical I/O words across connected expansion racks up to the system maximum of 5120 bits.

• What shielding measures are required for peripheral cable runs?

  Use double-shielded twisted-pair cables with 360-degree ground clamps connected directly to the control panel earth bar.
