Functions of the input module

Table 3 describes the functions of A/D conversion module.

Table 3 – Performance specifications

Function Item

Details

Channel Run/Stop setting

Specify Run/Stop of the channel to execute A/D conversion.

If the unused channel is set to Stop, the Run time can be

reduced.

Input voltage/current range

setting

Specify analog input range to be used.

Four input ranges are available for voltage input module while

two input ranges are available for current input module.

Output data format setting

Specify digital output type.

Four output data formats are provided in this module.

A/D conversion methods

Sampling processing: This is performed if A/D conversion type

is not specified.

Filter processing: This is to introduce delay when there is a

noise or sudden change of input value.

Average processing: Average A/D conversion value based on

frequency or time output.

Function to detect input

disconnected

The user program detects if an analog input with the range of 1

~ 5V (4 ~ 20mA) is disconnected.

The following are the three A/D conversion functions.

•

Sampling processing

•

Filter processing

•

Average processing
