The Omron CS1W-CLK23, also cataloged as the CS1W-CLK23 Controller Link Unit, operates as a dedicated hardware component for deterministic network data exchange within Omron CS1 Series PLC backplanes.

Hardware Architecture & Suffix Breakdown

• CS1W: CS Series CPU bus unit system classification code.
• CLK: Controller Link dedicated communications function designation.
• 2: Medium variant identifier denoting wired shielded twisted-pair physical layer configuration.
• 3: Optical/Electrical hardware generation revision designator.

Operational Parameters

Backplane Bus & Network Determinism

The unit interfaces directly with the CS1 CPU backplane bus communication velocity framework, processing high-speed data links and message services concurrently. Backplane power utilization remains optimized at 0.33 A under standard 5 VDC bus operation, limiting heat dissipation across adjacent slots. Network synchronization relies on token-ring passing over shielded twisted-pair cabling, maintaining deterministic updates across nodes while preventing bus contention during heavy messaging traffic load. Firmware flash compatibility ensures reliable protocol handling across varying CS1 CPU processor generations.

Kit Packaging Contents

• 1 x CS1W-CLK23 Controller Link Unit
• 1 x Terminal Block Connector (Mounted)
• 1 x Instruction Sheet

Physical Installation Protocol

• Ensure the CS1 PLC rack system main power supply is completely switched off prior to inserting or removing the module.
• Mount the unit securely into a designated CS1 CPU Bus Unit slot, ensuring the backplane connector locks flush without forced angle entry.
• Terminate the wired shielded twisted-pair cable using the correct impedance rating and ground the shield wire at a single point to prevent ground loops.
• Set the rotary unit number switches on the front panel to an unassigned node address within the 1 to 126 range before powering on the system.

Technical Support FAQ

• Does the CS1W-CLK23 support hot-swapping on an active backplane?

  No, power to the CPU rack must be completely disconnected before inserting or removing the module to prevent backplane bus damage.

• What is the total current draw of this module from the backplane?

  The unit draws 0.33 A at 5 VDC from the internal CPU rack backplane power supply.

• What is the maximum number of CS1W-CLK23 units per CPU rack?

  A maximum of 8 Controller Link Units can be mounted to a single CS1 CPU Unit, provided power budget constraints are met.

• Can this unit run on a duplex optical fiber network setup?

  No, the CS1W-CLK23 model is designed exclusively for non-duplex wired shielded twisted-pair media architectures.

• How many unit numbers are allocated to this module on the backplane?

  The unit allocates exactly 1 unit number on the CS1 CPU Bus Unit address map.

• How should cable shielding be terminated on the terminal block?

  Connect the shield braid directly to the designated shield terminal and tie it to functional earth at one central grounding point.

• What communication services run simultaneously on this unit?

  The hardware supports both cyclic data link updates and asynchronous explicit message servicing over the same network cable.

• What firmware requirement exists for backplane compatibility?

  The unit operates with standard CS1 CPU system firmware; verify node switch settings match system configuration software settings.
