3.4.1 Sampling processing

MELSEC-A

The A/D conversion is performed successively for the analog input, and the converted digital output values are stored in the remote register.

The processing time to store the digital output value into the remote register after the sampling processing differs depending on the number of A/D conversion enabled channels.

(Processing time) Number of A/D conversion enabled channels) 1 (ms)

Maximum conversion speed

[Example] When three channels, channels 1, 2, and 3 are enabled for conversion: 3×1 = 3 (ms)

3.4.2 Moving average processing

The specified count of digital output values imported per sampling time are averaged to find a value, which is then stored into the remote register.

Since average processing is performed with data shifted per sampling, the most recent digital output value is available.

Average processing can be performed without changing the conversion speed.

Use moving average processing count setting (address RWwm+2) to set the number of moving average processings.

The count can be selected from among four types: 4, 8, 16 and 32 times.
