Figure 2.12A - Typical Thermistor Input Connections
Using the Slope and Intercept, it is simple to calculate the actual temperature based on the analog input reading, the slope and the
intercept. The calculation in the ladder diagram is:
Temperature = (Analog Input x Slope) + Intercept
Figure 2.12B illustrates this calculation in a ladder diagram format. For this example, the analog input (AN0) is also being averaged using the AVG function block. Please note: All the variables must be in a REAL format for the calculations of the MULT and
ADD function blocks.
