    GE Fanuc Genius I/O Troubleshooting

    A Genius Block has two LEDs that indicate vital diagnostic information regarding the Block and the field circuits that are connected to it.

    • 'Unit OK' LED
    • 'I/O Enabled' LED
    • At startup, both LEDs shall be powered ON (Steady RED Light).

    Details concerning these LEDs are indicated in the subsequent sub-sections.

  • STEP 2 - Healthy Genius Block

    A Genius Block that does not communicate with the Genius Bus Controller (in other words with the PLC) shall exhibit the following characteristics:

    • 'Unit OK' LED - Steady ON State
    • 'I/O Enabled' LED - OFF State

    Corrective Action

    • Cycle Power to the GBC.
    • Verify CPU is RUN/ENABLED.
    • Verify Genius Bus Connection is intact and terminated properly.
    • Verify Baud rate of the GBC and all Genius Blocks (usually indicated on the blocks as a sticker) are the same.
  • STEP 4 - Genius Block with Forced Channel(s)

    Environmental Specifications

    Genius I/O blocks meet the following specifications for vibration, noise, and ambient temperature.

    Vibration

    Genius I/O blocks are compact and sturdy; they perform well in conditions where vibration is a factor. All Genius I/O block designs are vibration-tested (according to Mil-Std 810C and IEC 68-2-6) to meet the following specifications:

    • 5 to 10 Hz .200 in displacement (peak to peak)
    • 10 to 200 Hz at 1 g
    • Shock: 15G

    Noise

    Genius I/O blocks are resistant to noise levels found in most industrial applications when installed according to accepted industry practices. This includes proper separation of wiring by voltage and power levels.

    Blocks are tested to the following noise specifications:

    • Radiated: FCC part 15, section J, class A, Computing Devices
    • Received: NEMA ICS 2-230

    ANSI/IEEE C37.90 (Relay and relay systems associated with Electrical Power Apparatus)

    Temperature

    I/O blocks operate reliably in temperatures up to 60C (140F). Temperatures are measured adjacent to the block at the bottom of the Electronics Assembly. Between 35C and 65C (95-149F) each 10C reduction in the ambient temperature increases the electronics Mean Time Between Failures by a factor of two.
