Allen-Bradley · Logix and SLC PLC

What does F014 mean?

This fault signifies a general command execution failure, specifically highlighting a PLC-3 histogram overflow. This indicates an issue with data collection exceeding buffer limits within a PLC-3 system, preventing the command from completing.

Common Causes

  • Data collection parameters exceeding the PLC-3's histogram buffer capacity.
  • PLC-3 processor internal execution error preventing command completion.
  • Legacy PLC-3 system limitations encountering high data rates.

Repair Steps & Checklist

  1. 1

    Verify PLC CPU and memory utilization to identify potential resource exhaustion.

  2. 2

    Inspect PLC diagnostic buffers and error logs for additional related faults or warnings that may provide context.

  3. 3

    Review the PLC-3 histogram configuration parameters, such as buffer size, sampling rate, and trigger conditions, for misconfiguration.

  4. 4

    Check network traffic and communication load on the PLC-3's network interface to identify potential overload sources contributing to data overflow.
