Temperature Sensor Unit
•
Setting the Temperature Range
Set the temperature range with the rotary switch on the front panel of the Temperature Sensor
Unit. If the rotary switch is set to 1 for a CP1W-TS001 Temperature Sensor Unit, the temperature
range is 0.0 to 500.0°C.
•
Temperature Data Storage Format
Temperature data is automatically stored in words in the Input Area allocated to the Temperature
Sensor Unit as an Expansion Unit using four-digit hexadecimal.
Example: 100°C is stored as 0064 hex.
•
When the range code is a decimal number to one decimal point, the value is multiplied by a
factor of 10 and converted to a hexadecimal number without a sign, then stored as binary
data.
Example: 500.0°C multiplied by 10 is 5000 decimal. This is converted to 1
388
in hexadecimal
and stored.
•
If the temperature is negative, it is stored as signed hexadecimal.
Example: -200°C is stored as FF
38
hex.
z
PIDAT Instruction
The PIDAT instruction treats the PV as unsigned hexadecimal data (0000 to FFFF hex). Signed data
cannot be used, so if the temperature range includes negative values, apply scaling with the APR
instruction.
