For 0 to +10 V, 0 to +5 V K0 to K+32000
For +1 to +5 V K0 to K+25600
For 0 to +20 mA K0 to K+32000

3.4.4 Input Processing Timing
■
Timing when data is retrieved in the operation memory (WX)
● Analog input values for all channels are converted into digital values in units of 1 ms.
● Converted digital values are retrieved into the operation memory at the I/O refresh timing.
● Analog input value conversion is not synchronized with I/O refresh of the operation memory.
Therefore, the latest data is retrieved into the operation memory at the I/O refresh timing.
