4-4. Reading Averaged Value

4-4. Reading Averaged Value
The temperature data measured by the thermocouple input unit is automatically converted to normalized and Celsius
data. These data are averaged over five times inside the thermocouple input unit and the averaged values for each
channel are stored in the shared memory as:
Shared memory
address (word units)
K28
K29
K30
K31
K40
K41
K42
K43
J Averaged value reading program
Celsius data stored in the shared memory of the thermocouple unit is read by executing the F150 (READ)/P150
(PREAD) instructions as follows.
Condition:
- Thermocouple input unit slot position: Slot 2 position
- Number of enabled channels: 4 channels (CH0 to CH3)
Program example 1
- Type of data read : Averaged value of Celsius data (addresses K28 through K31 of the shared memory)
- CPU registers for storing normalized data: DT30 to DT33
