Function Hierarchy The MAT operator adheres to the typical rules of formula calculation:
First, MAT solves any SQRT, e^x, integral, differential, linear, and polynomial
functions in a left to right order unless overridden by brackets.
Next, it performs multiplications (*), divisions (/), additions (+), and subtractions (-) in
this order unless overridden by parentheses or brackets.
Change Existing Formula In the Control strategy work space, click the MAT icon using the right-hand mouse
button. The Mathematical Editor dialog box displays with the formula. Use the
highlight-and-change techniques as explained in the previous procedure to modify
formula as desired.
In the Switching logic work space, click the analog input condition that is the result of
a formula. The Mathematical Editor dialog box displays with the formula. Use the
highlight-and-change techniques as explained in the previous procedure to modify
formula as desired.
Digital Conversion To use digital point information in a formula, first convert the data into analog values.
The easiest way to do this is to connect the digital point to the XD1 input of the SWI
control icon. Set the X2 input of SWI to 1.00. Set the X3 input of SWI to 0.00.
Connect the SWI output to an analog flag. The MAT editor can use the analog flag
in formulas.
A drawback to this method is that the analog flag is internal only and is not visible to
the user.
Parameter Number
Descriptions Parameters exist for the square root, logarithm, integral, differential, polynomial, and
linear functions only. The following list gives parameter numbers for the square root
and logarithm functions only. See the appropriate section for the other functions
(INT, DIFT, POL, and LIN).
