Averaging Processing - Mitsubishi Electric MELSEC iQ-R User Manual

Averaging processing

Common
The A/D converter module performs the averaging processing on digital output values for each channel. The averaged values
are stored in the buffer memory.
The following three types of averaging processing are provided.
• Time average
• Count average
• Moving average
Time average
Medium speed
The A/D conversion is performed for the setting time and the averaging processing is performed on the total value excluding
the maximum and the minimum values. The averaged values are stored in the buffer memory.
■Setting time
The setting range of the time (for averaging) is 1 to 5000ms.
■Number of processing times
The number of processing times within the setting time changes depending on the number of channels where the A/D
conversion is enabled.
• Number of processing times (times) = Setting time/Sampling cycle
Ex.
The following shows the number of processing times with the setting below.

Setting time
8 (ms)/(4 (CH)  0.01 (ms)) = 200 (times)
Conversion is processed 200 times and the mean value is output.
