Input Settings and Conversion Values
Input Numbers
The Analog Input Unit converts analog inputs specified by input numbers. To
specify the analog inputs to be used, turn ON from a Programming Device the
D(m) bits in the DM Area shown in the following diagram.
Setting 0: Not used.
1: Used
• CS1W-AD041-V1: Inputs 1 to 4
• CS1W-AD081-V1: Inputs 1 to 8
The analog input sampling interval can be shortened by setting any unused
input numbers to 0.
Sampling interval = (1 ms) x (Number of inputs used) (See note.)
Note
Use 250
µ
s instead of 1 ms is set to a conversion time of 250
µ
s and
resolution of 8,000.
The conversion values in words for inputs that have been set to “Not used” will
always be “0000.”
For the DM word addresses, m = (unit number x 100)
Input Signal Range
Any of four types of input signal range (–10 to 10 V, 0 to 10 V, 1 to 5 V, and 4
to 20 mA) can be selected for each of the inputs.
CS1W-AD041-V1/AD081-V1
To specify the input signal range for each input, set from a Programming
Device the D(m + 1) bits in the DM Area as shown in the following diagram.
Note
There are only four inputs for the CS1W-AD041-V1.
