The FactoryTalk View Bar Graph object provides you with a graphic indication of analog signals. In addition, we will set thresholds to change the color of the bar graph. By the same token, you could use a Gauge object. <\/a>The object you use simply depends on the preferred appearance of the display. In this example, we will measure the temperature of a bearing. In this case, we prefer the bearing temperature to be between 100 and 180 degrees Fahrenheit. If the temperature is below 100 degrees, the gar graph will be yellow. Obviously, if the bar graph goes above 180, we want the color to be red. Similarly, a temperature between 100 and 180 will be green.<\/p>
