Configured for central logic execution and sequential scan processing in SYSMAC CS1 platforms, the Omron CS1H-CPU64H (CS1H-CPU64H CPU Processor) provides direct physical/electrical execution.

Memory & System Scaling Architecture

The CS1H-CPU64H constitutes a core central processing unit within the Omron SYSMAC CS1 architecture. The CS1H prefix denotes high-performance CPU hardware, while the 64H suffix specifies a 30 Kstep user program capacity combined with 64 Kwords of data memory. This hardware profile supports up to 7 expansion racks and 5,120 local I/O bits.

System Specifications

Deterministic Network Bus & System Execution

The internal processing core drives determinism across local and remote racks, optimizing backplane bus communication velocity across high-density I/O configurations. Balanced cycle timing maintains high I/O density scaling while preserving complete hardware firmware flash compatibility across network cards and special function units.

Package Configuration

• 1 x Omron CS1H-CPU64H CPU Processor

Cabinet Mounting and Hardware Wiring Protocol

• Ensure the backplane power supply is fully de-energized before inserting or releasing the CPU unit from the rack slot.
• Align the lower edge guide pins into the CPU slot before pressing the upper retention clip firmly into place.
• Ground the RS-232C cable shielding directly to the enclosure single-point ground plate to prevent noise coupling.
• Keep the front panel peripheral port protective cover installed when programming cables are disconnected.

Frequently Asked Questions

• What is the basic LD instruction processing speed of the CS1H-CPU64H processor?

  The processor executes basic LD instructions in 0.02 us, allowing high-speed system scan cycle timing.

• What memory limits are available for user programs and data storage?

  The hardware provides 30 Ksteps of ladder program memory and 64 Kwords of internal data memory space.

• How many expansion racks can be connected to a CS1H-CPU64H system?

  The unit supports connection of up to 7 expansion racks, handling up to 5,120 direct I/O address bits.

• What communication interface options are integrated directly on the front panel?

  The front interface features one dedicated RS-232C serial port and one Omron peripheral interface port.

• Can the CS1H-CPU64H processor unit be hot-swapped during system operation?

  No, hot-swapping is strictly prohibited; backplane power must be turned off prior to CPU installation or removal.

• What backplane power budget does the CS1H-CPU64H draw from the rack power supply?

  The CPU module draws a nominal current load of 0.82 A at 5 VDC directly from the internal backplane.

• How is system data memory retained during prolonged power outages?

  Internal RAM data memory and real-time clock functions are maintained by a replaceable lithium battery unit.

• What operating temperature range is permitted inside the control panel cabinet?

  The CPU unit functions within an ambient panel operating temperature range of 0 to 55 deg C.
