Follow the procedure outlined below when using Analog Input Units.
Installation and Settings
1,2,3... 1. Set the operation mode to normal mode. (See note 1.)
2. Select voltage/current input using the switch at the back of the terminal
block. (See note 2.)
3. Wire the Unit.
4. Use the unit number switch on the front panel of the Unit to set the unit
number. (See note 3.)
5. Turn ON the power to the PLC.
6. Create the Input tables.
7. Make the Special Input Unit DM Area settings.
• Set the input numbers to be used.
• Set the input signal ranges.
• Set the number of mean processing samplings.
• Conversion time and resolution
8. Turn the power to the PLC OFF and ON, or turn ON the Special I/O Unit
Restart Bit to ON.
When the input for the connected devices needs to be calibrated, follow the
procedures in
Offset Gain Adjustment below. Otherwise, skip to Operation
below.
Offset and Gain Adjustment
1,2,3... 1. Set the operation mode to adjustment mode. (See note 1.)
2. Select voltage or current input. (See note 2.)
3. Turn ON the power to the PLC.
4. Adjust the offset and gain.
5. Turn OFF the power to the PLC.
6. Set the operation mode to normal mode. (See note 1.)
Operation
1,2,3... 1. Turn ON the power to the PLC.
2. Ladder program
• Read conversion values or write set values by means of MOV(021)
and XFER(070).
• Specify the peak hold function.
• Obtain disconnection notifications and error codes.
Note 1. Setting the Operation Mode
The operation mode can be changed either by setting the DIP switch on
the rear panel of the Unit or changing the DM Area settings. When normal
mode is set both in the DIP switch and in the DM Area settings, the Unit
operates in normal mode. If adjustment mode is set in either or both of the
settings, the Unit operates in adjustment mode. The operation mode selec-
tion setting is allocated in DM word m+18 for CS1W-AD041-V1 and CS1W-
AD081-V1 and in DM word m+19 for CS1W-AD161.
2. Selecting Voltage/Current Input
With the CS1W-AD041-V1 and CS1W-AD081-V1, remove the terminal
block and set the DIP switch located at the back. With the CS1W-AD161,
