Analog Input Functions and Operating Procedures Section 3-6
Example 1 In this example, the conversion data from only one input is read. (The unit
number is 0.)
Example 2 In this example, the conversion data from multiple inputs is read. (The unit
number is 0.)
For details regarding conversion value scaling, refer to Scaling on page 446.
3-6-2 Conversion Time/Resolution Setting
Bits 08 to 15 in DM word m+18 can be used to set the conversion time and
resolution for the CJ1W-AD041-V1 and CJ1W-AD081-V1 to increase speed
and accuracy.
This setting applies to analog inputs 1 to 8 (1 to 4 for the CJ1W-AD041-V1),
i.e., there are not individual settings for each input.
Note When DM Area settings have been carried out using a Programming Device,
be sure to either cycle the power supply to the PLC, or turn ON the Special I/
O Unit Restart Bit. The contents of the initial settings in the DM Area will be
transferred to the Special I/O Unit when the power is turned ON or the Special
I/O Unit Restart Bit is turned ON.
