AVE (average)

The AVE instruction calculates a running average over a number of defined samples and stores the value at each cycle.
Operation details:
  • The defined number of samples (N) cannot exceed 127.
  • When setting or changing the value for N, set RUN to FALSE, then set it back to TRUE.
  • If the RUN command is FALSE (reset mode), the output value is equal to the input value.
  • When the maximum number of stored values is reached, the first stored value is erased by the last one.
  • Using floating-point data types could result in inaccurate calculations due to the rounding limitations inherent in floating-point mathematics.
Languages supported: Function block diagram, ladder diagram, structured text.
This instruction applies to the Micro810, L20E, L50E, and L70E controllers.
