RatioLimitsInv (Status1.11)

Invalid Ratio Clamping Limits

Allen-Bradley · Logix 5000 Controllers

What does RatioLimitsInv (Status1.11) mean?

This fault indicates invalid ratio clamping limits. This occurs when RatioLLimit is less than 0 or RatioHLimit is less than RatioLLimit for the PIDE instruction. The PPID instruction's Sts_ErrRatioLim is set when Cfg_RatioLoLim is greater than Cfg_RatioHiLim. Note that PPID does not set this error condition when Cfg_RatioLoLim is less than 0.

Common Causes

  • RatioLLimit parameter configured to be less than 0 (PIDE)
  • RatioHLimit parameter configured to be less than RatioLLimit (PIDE)
  • Cfg_RatioLoLim parameter configured to be greater than Cfg_RatioHiLim (PPID)

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Access the PIDE or PPID instruction configuration within the programming software

  2. 2

    Verify RatioLLimit (PIDE) is set to 0.0 or a greater value

  3. 3

    Verify RatioHLimit (PIDE) or Cfg_RatioHiLim (PPID) is numerically greater than RatioLLimit (PIDE) or Cfg_RatioLoLim (PPID)

  4. 4

    Ensure Cfg_RatioLoLim (PPID) is less than or equal to Cfg_RatioHiLim
