      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • Four independent communication channels let FS-USI-0001 connect the Safety Manager controller to Ethernet and serial systems while retaining separate communication diagnostics.
      Communication: Two Ethernet and two serial channels
      Processor: Motorola 8260 communication processor
      Design: Non-conformal-coated FS variant
      FS-USI-0001 is the non-conformal-coated Universal Safety Interface for the Safety Manager controller chassis. A Motorola 8260 processor handles communication to external devices and other Safety Managers. The interface separates external communication handling from the controller safety functions; the complete configured system determines the permitted communication paths.

      Channels A and B use auto-ranging 10/100 Mb Ethernet through RJ45 connectors and the applicable UCOM-HSE connection arrangement. Channels C and D are general-purpose serial channels using 10-pin AMP connections with the applicable DCOM-232/485 arrangement. Module EEPROM retains specific information including two MAC addresses and the hardware revision. The design has 8 Mbyte Flash, 4 Mbyte local SRAM and 256 kilobyte shared RAM.

      Transmit and receive LEDs report channel activity, while the status indicator distinguishes normal operation, hardware error and power-down or booting. A dedicated watchdog can take communication channels offline on failure. The USI-0001 design supports insertion and removal in a running system without interrupting the application program; communication availability and site procedures still require planning. V1.1 and V1.2 design improvements are revision-specific and must not be assumed for an unidentified unit.
      Controller platform reference: Safety Manager. Match the installed hardware and configuration.
      Technical downloads for FS-USI-0001: an original Honeywell reference excerpt and an Apter Power installation planning guide.
      The listed architecture applies to USI-0001. The supplied FS-USI-0001 identity does not state a revision; V1.1/V1.2 improvements and revision-specific approvals or ratings require the actual unit marking. The planning guide is prepared by Apter Power; apply the complete manufacturer instructions and the stated applicability boundaries.
      System and supply context: The listed architecture applies to USI-0001. The supplied FS-USI-0001 identity does not state a revision; V1.1/V1.2 improvements and revision-specific approvals or ratings require the actual unit marking. Accessories are included only when itemized in the quotation.

      Platform applications: The following applications describe Safety Manager functions. Match the complete FS-USI-0001 identity to the installed system before selecting a replacement.
      Prepare FS-USI-0001 against the installed configuration and applicable Honeywell instructions. Plan isolation and the resulting interruption of system operation before replacement.
      Preserve revision identity

      Read the full FS-USI-0001 marking and hardware revision before applying revision-specific requirements.

      Match external interfaces

      Confirm the UCOM-HSE or DCOM arrangement and cable type for each used channel.

      Preserve network configuration

      Record MAC-related configuration, addressing and the approved communication topology.

      Plan communication interruption

      Hot swap support does not maintain an unplugged communication link; assess the connected systems before removal.

      Check diagnostics

      Review status, Tx/Rx activity and watchdog-related faults before returning the communication path to service.

      Validate system behavior

      Verify intended data exchange and the approved control-program handling of communication failure.

      Technical notes

      Installation relationship: Channels A and B use auto-ranging 10/100 Mb Ethernet through RJ45 connectors and the applicable UCOM-HSE connection arrangement. Channels C and D are general-purpose serial channels using 10-pin AMP connections with the applicable DCOM-232/485 arrangement. Module EEPROM retains specific information including two MAC addresses and the hardware revision. The design has 8 Mbyte Flash, 4 Mbyte local SRAM and 256 kilobyte shared RAM.

      Configuration: The listed architecture applies to USI-0001. The supplied FS-USI-0001 identity does not state a revision; V1.1/V1.2 improvements and revision-specific approvals or ratings require the actual unit marking.

      Technical reference: Honeywell Safety Manager Hardware Reference, EP-SM.MAN.6284, Release 151, Issue 1.0 Revision 2.

      • Which Ethernet rates does FS-USI-0001 support?
        The two Ethernet interfaces automatically select between 10 and 100 Mb operation.
      • Which connector arrangement is used by FS-USI-0001?
        Ethernet uses RJ45 connections; the serial channels use 10-pin AMP connections with the applicable serial interface arrangement.
      • What memory architecture is used by FS-USI-0001?
        The design includes 8 Mbyte Flash, 4 Mbyte local SRAM with error detection and correction, and 256 kilobyte shared RAM.
      • How does FS-USI-0001 report communication and hardware state?
        Separate Tx and Rx indicators show channel activity. The status LED is green for no detected hardware error, red for a hardware error, and off during power-down or booting.
      • Can FS-USI-0001 be removed while the controller is running?
        The USI-0001 design supports hot swap without interrupting the application program. Plan the loss of its communication paths and follow the approved system procedure.
      • Does FS-USI-0001 identify a specific hardware revision?
        No revision is included in the supplied model string. Check the unit marking before applying V1.1 or V1.2 design-improvement statements or revision-specific ratings.
