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
