The Omron CS1G-CPU44H, also cataloged as the CS1G-CPU44 CPU Unit, operates as a dedicated hardware component for central logic execution and system backplane routing within CS1-G industrial rack controller systems. It processes instruction execution cycles, manages local expansion bus lines, and handles memory registers across connected rack racks. The unit executes programmed operations directly without reliance on external coprocessor modules.

Part Number Code Breakdown

• CS1G: Designates standard CS1-G series programmable controller platform architecture.
• CPU44: Identifies CPU module processing capacity tier with 30K step program memory and 1280-point I/O capacity limits.
• H: Denotes high-speed instruction execution engine hardware revision.

Physical & Technical Specifications

Backplane Synchronization & Hardware Compatibility

The module interface coordinates backplane bus communication velocity Licences protocol traffic to ensure synchronous I/O scan updates across all connected rack slots. Optimized firmware flash compatibility maintains signal timing alignment when communicating with specialized network and motion control modules, while high-density I/O density scaling preserves execution deterministic behavior across the rack backplane.

Included Package Hardware

• 1 x Omron CS1G-CPU44H CPU Unit
• 1 x Protective Connector Port Cover
• 1 x Hardware Instruction Sheet

Cabinet Installation & Wiring Directives

Module Mounting & Backplane Attachment

• Align the upper and lower guides of the CPU unit with the leftmost slot on the CS1 backplane.
• Push the module firmly into the backplane connector until the locking tab engages fully.
• Secure the backplane frame to the metallic enclosure mounting plate using M4 screws to ensure low impedance ground connection.

Communication Wiring & Interference Control

• Use double-shielded twisted-pair cables for peripheral and RS-232C serial port connections.
• Connect the cable shield drain wire directly to the protective earth terminal at a single ground point.
• Maintain a minimum clearance of 200 mm between communication wiring lines and high-voltage power conduits.

Frequently Asked Questions

• Can the CS1G-CPU44H unit be installed or replaced while the backplane is energized?

  No. Main power supply to the rack backplane must be completely shut off prior to removing or inserting the CPU module.

• What memory type retains user programs during prolonged system shutdowns?

  Program memory and DM data are retained in flash memory backed up by an internal lithium memory battery.

• What is the maximum I/O point expansion capacity supported by this CPU model?

  The CS1G-CPU44H manages up to 1280 local and expansion rack digital and analog I/O points across the platform.

• How is system power supplied to the CPU module internal circuitry?

  Power is drawn directly from the 5 VDC bus supplied by the dedicated power supply unit mounted on the rack.

• What mounting method is required for the CS1G-CPU44H controller assembly?

  The unit mounts directly onto a dedicated CS1 series CPU rack baseplate secured within an enclosure.

• How do status LEDs indicate CPU module diagnostic fault conditions?

  Front panel LEDs display operational states including RUN, MONITOR, ERROR, and ALARM for real-time diagnostics.

• Does this unit feature integrated serial communication interfaces?

  Yes, the unit provides a peripheral port and an RS-232C port for programming devices and serial equipment.

• Is additional firmware configuration required when replacing a CS1G-CPU44 module?

  Ensure system DIP switches match the original unit settings and verify firmware compatibility with existing units.
