registers can be set in the Fault Status group box with
the associated input boxes and Write buttons. This data
is input in hexadecimal format only. The master-initiated
fault-detection cycle can be run from the Fault Status
group box by selecting the corresponding button. Note
that if using the Manual Timing Mode that once Step 1
has been selected it must be followed by selecting Step 2.
Graphing
This GUI comes complete with a very simple graphing
tool located in the Graphing/Data tab (Figure 2). The
Graphing/Data tab plots the polled values in a graph.
Polled values are collected any time the Polling feature
is active. Three data options can be displayed; the
calculated Resistance Value, the temperature calculated

using the Simple Linearizing Method, or the temperature
calculated using Callendar­Van Dusen Equation with
IEC 751 coefficients and the user-supplied RTD nominal
0°C resistance. The Simple Linearizing Method is the
straight-line approximation, as defined by the equation
shown on the Registers tab in the RTD Resistance
Register group box. Click the desired checkbox to plot
the collected data. The graph displays the latest 10,000
polled values and when the polled count reaches 10,000,
the graph deletes the oldest polled values and adds a new
polled value. To reset and clear all collected data, select
the Clear Graph button. To save all the data graphed to a
comma-separated value (.CSV) file, press the Save Data
button and provide a folder and filename.
