6-1-3 Structure of ST and Example
Using general expressions, ST programming requires no special knowledge.
Remember the following two rules:
(1) Use a colon and an equals sign (:=) to assign a value to a variable.
(2) Statements must end with a semicolon (;).
Example
An example of the statement to calculate the distance between two points using Pythagoras'
theorem is shown below.
Just apply the formula.
■ Formula
𝐋𝐞𝐧𝐠𝐭𝐡 =
�
(𝐗𝟏 − 𝐗𝟎)
𝟐
+ (𝐘𝟏 − 𝐘𝟎)
𝟐
■ ST program
Length := SQRT((X1-X0)**2+(Y1-Y0)**2);
* SQRT: Square Root
