8 – Configuring Points
184 R400
To define a format for this:
1 Define an unscaled data format.
2 In the Field Value section select INT2 from Data type, and set the Start bit
to 0 and Width to 16.
3 Select Signed value. (Do not select Swap words or Swap bytes.)
4 Enter NaN in Minimum and Maximum.
5 In the Conversion section select Linear. Set the node values as follows.
Example 2
A device stores values in two 16-bit registers in little-endian format. The value
stored is an IEEE floating point number. However, the response curve of the
instrument that generates the value is shown in the following figure.
To define a data format for this:
1 Determine the nodes you need to define to obtain the desired accuracy. In
this example, you decide to define four nodes, as shown in the following
figure. (The first node is at 0,0.)
