Application Examples
This chapter provides two application examples to help you use the
thermocouple input module. They are defined as a:
•
basic example
•
supplementary example
The basic example builds on the configuration word programming
provided in chapter 6 to set up one channel for operation. This setup
is then used in a typical application to display temperature.
The supplementary example demonstrates how to perform a
dynamic configuration of all four channels. The example sets up an
application that allows you to manually select whether the displayed
thermocouple input data for any channel is expressed in °C or °F.
Basic Example Application Setup (Display a Temperature)
This example indicates the temperature of a bath on an LED display.
The display requires BCD data, so the program must convert the
temperature reading from the thermocouple module to BCD before
sending it to the display. This application will display the temperature
in °F.
