The Omron CS1H-CPU63H, also cataloged as the CS1H-CPU63H CPU Unit, operates as a dedicated hardware component for high-speed central processing and sequential ladder execution within SYSMAC CS1-series platforms.

Architecture and Processor Classification

The CS1H-CPU63H is a high-speed central processing unit within the Omron SYSMAC CS1 architecture. The CS1H prefix identifies high-performance CPU hardware, while the 63H designation specifies a 20 Kstep program memory and 64 Kword data memory capacity. This engine supports system expansion up to 7 racks and 5,120 local I/O points.

Technical Performance Parameters

Backplane Communication Velocity and Deterministic Execution

The internal processor manages bus arbitration to preserve high backplane bus communication velocity across expansion chassis. Optimized logic execution enhances overall I/O density scaling and maintains absolute hardware firmware flash compatibility across special I/O cards, motion modules, and communication units.

Shipping Package Content

• 1 x Omron CS1H-CPU63H CPU Unit

Field Mounting and Wiring Protocol

• Isolate all incoming power feeds to the PLC rack before mounting or extracting the CPU module.
• Insert the lower module alignment tabs into the backplane slots before locking the upper retention latch.
• Connect RS-232C communication cable shielding directly to the panel earth bus to mitigate serial line interference.
• Keep protective covers fitted over unused peripheral ports and memory card slots to prevent airborne particle contamination.

Technical FAQ

• What is the basic LD instruction processing speed of the CS1H-CPU63H unit?

  The processor executes standard basic LD instructions in 0.02 us for deterministic scan times.

• How many expansion racks can be controlled by the CS1H-CPU63H processor?

  The module manages up to 7 expansion racks, controlling up to 5,120 direct addressable I/O bits.

• Is hot-swapping supported for the CS1H-CPU63H on an active backplane?

  No, live hot-swapping is prohibited; backplane power must be isolated prior to unit insertion or removal.

• What communication interfaces are integrated on the CPU front panel?

  The CPU features one built-in RS-232C serial communication port and one Omron peripheral port.

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

  The processor provides 20 Ksteps of user program memory and 64 Kwords of internal data memory space.

• What power load does the CS1H-CPU63H draw from the 5 VDC backplane rail?

  The unit draws 0.82 A at 5 VDC directly from the rack power supply module via the backplane bus.

• How is volatility managed for data memory during control panel power losses?

  Internal RAM variables and real-time clock functions are sustained by an internal lithium battery.

• What ambient operating temperature limit applies to enclosure installations?

  The processor functions continuously in ambient enclosure temperatures ranging from 0 to 55 deg C.
