Specifications Section 2-1
4. Data Exchange with the CPU Unit
Note The resolution/conversion time setting and operation mode setting
are supported only by version-1 Analog Input Units.
5. Input signal ranges can be set for each input.
6. Voltage input or current input is selected for the CS1W-AD041-V1 and
CS1W-AD081-V1 by using the voltage/current switch at the back of the ter-
minal block. Voltage input or current input is selected for the CS1W-AD161
by wiring the connector terminals. Voltage/current selection for input rang-
es 1 to 5 V or 4 to 20 mA can be set in DM word m+52.
7. Use the analog input voltage/current value within the specified input signal
range. Exceeding the specified range may result in malfunction.
8. With Analog Input Units, the resolution can be changed from 4,000 to
8,000 and the conversion time changed from 1 ms to 250
µs in DM word
m+18 for CS1W-AD041-V1 and CS1W-AD081-V1 or in DM word m+19 for
CS1W-AD161.
9. The following are adjusted at the factory.
CS1W-AD041-V1/081-V1: Voltage inputs
CS1W-AD161: Voltage inputs and current inputs
Calibration conditions: Recommended Terminal Block-
Connector Conversion Unit used. (The factory calibration
for a current input can be made effective by setting DM
word m+52.)
To use current inputs with the CS1W-AD041-V1/081-V1 or to use the
CS1W-AD161 with products other than the recommended ones, adjust the
offset and gain as required.
10. A/D conversion time is the time it takes for an analog signal to be stored in
memory as converted data after it has been input. It takes at least one cy-
cle before the converted data is read by the CPU Unit.
11. Input disconnection detection is valid only when the 1 to 5-V or 4 to 20-mA
range is set. If there is no input signal for when the 1 to 5-V or 4 to 20-mA
range is set, the Disconnection Detection Flag will turn ON.
