Temperature Sensor Units Section 7-5
Converted Analog Data
“m” is the last input word allocated to the CPU Unit, Expansion I/O Unit, or
Expansion Unit connected immediately before the Temperature Sensor Unit.
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~W10.13 turns ON at the
time of open-circuit detection.
DIP Switch Setting
SW1 OFF K
SW2 OFF °C
SW3 NC
SW4 OFF Thermocouple
SW5 ON Analog
SW6 ON 1 to 5V/4 to 20mA
