Startup Operation
After power is turned ON, approximately 1 s is required for the first conversion
data to be stored in the input word. During that period, the data will be 7FFE.
Therefore, create a program as shown below, so that the ladder can start to
operate with valid conversion data in input words.

Programming Example
The following programming example shows how to store the input data of
CP1W-TS003 (4 inputs) in D0 to D3, and W10.00 to W10.03 turn ON at the
time of open-circuit detection.
